Hole punch

February 9, 2016

Hole punches need to be in your tool box. So often problems with number plates and a host of other race day issues can be elegantly solved with even a cheap hole punch. I can’t count how many times I’ve wished to have one in my hand at just the right moment.

A cheap punch is ok but a good one is even better. I finally invested in a pair of serious iterations. I got a pair of long reach punches. 1/4″ and 1/8″. Very cool. Perfect for race number plates and a whole lot more.

McGill Utility #300 Series 1/4″ Round, MCG303
McGill Utility #300 Series 1/8″ Round, MCG301

There are even lots of fun shapes you can get if you like.

Anyway. Make sure you have some kind of hole punch in you race box.


These are nice. They can reach well into the center of a full size number plate.



JIS Cross Head Screws and Drivers

February 9, 2016

JIS – Japanese Industrial Standard I work on a lot of Japanese machines. Motorcycles, bicycle parts, cars, and electronics. A lot of people do the same. Here in the United States, many mechanics and technicians use the incorrect tools and cause issue to the fasteners of these machines. It’s a shame. Japanese produced goods use […]

The wonderful world of torque

January 23, 2016

I’m a very lazy mechanic. I don’t want to do any more work or pay any more attention than I need to when I’m repairing something or tuning a system. Because of that, like most mechanics, rather than use a torque wrench on every bolt I turn I’ve learned a feel for the metal, parts, […]

Paying in

January 11, 2016

Yesterday was a fun ride. Getting my injured knee back up to speed has taken longer than I thought. I folded my left knee sideways snowboarding a couple of weeks ago. I think it’s fine but the pain and swelling have persisted and give me doubts. Anyway, I felt good on Sunday and we took […]

An AngleSet for an AngleSet

January 8, 2016

Following my last post where I was able to adapt and move forward in development, I produced an offset insert for the 55mm Euro lower headtube on my new 2016 Scott Genius LT. One of my goals is to see how long I can run this thing so it goes super fast down hills. It’s interesting how […]

55mm to 49mm Headset Adapter for Scott

January 2, 2016

While putting my new 2016 Scott Genius LT together, I learned about yet another industry ‘standard’. The ZS55. Not 56, 55. WTF? The headset on this frame is ZS44/28.6 top and ZS55/40 bottom. ZS55 is a rather rare size. There seems to be no good reason for this divergence. This is referred to as European Standard. […]

Going full enduro

December 21, 2015

My riding in the past year and a half or two has changed quite a bit. I’m now 46 and my strength and stamina isn’t what it was in the past. Training hard still resulted in slower climbing and shorter rides. The truth is that I wasn’t born to be a real athlete and years of […]

The pro and the schmo. Dusting off some old school tricks.

December 1, 2015

Ronen Sarig is a total noob. Julien Absalon is one of the best XC racers there is and a World and Olympic champion. The two have one very uncommon (in a modern sense) thing in common. They both have tied and soldiered spokes on their bicycle wheels but for different reasons. Julien Absalon (BMC) has wire tied […]

The rides of early November 2015

November 24, 2015

We’ve been hard at work on riding our Bay Area trails. The theme of 2015 seems to be to ride the trail bike like a DH rig. Crush rocks. Smash everything. A trip to Pacifica, Stafford, and yet another trip to Rockville was the score for this weekend. Quite the diverse selection. Loam, jumps, and rocks. […]

Shimano Brake Pads

November 18, 2015

With the introduction of the 8000 & 9000 offroad groups, Shimano has changed it’s brake pads for mountain and post mount road cooling fin type.

A weekend of going big

November 17, 2015

This weekend ended up having to turn out like this I guess. A thrill ride of adrenaline. Just what I like when I’m out having fun. A week ago, I was on a small group ride in Marin. We were on a section of trail that is about as basic as it gets. Wide, groomed, […]

Maxle, Maxle, Bo-baxle

November 12, 2015

Here’s a fun little hop up for your haggard older Maxle Lite fork. I love Rockshox forks. The post Reba era has been good to the brand and they only get better. Now, everything has through-axles. Until recently, the lighter forks got Maxle Lite through axles. This was great. A much stiffer and easier fork. […]

In the past weeks, I’ve rebuilt 3 reverbs. A Reverb A1 for a friend and two Reverb Stealth A2s of my own. I’d done a few others in the past, especially when they first came out and there were all kinds of issues and a learning curve for most. Traditionally, 90% of all Reverb issues […]

Yesterday I raced the Rockhopper Enduro in Rockville Regional Park. It was a great event that raised funds for local high school league racing. The weather and conditions were perfect.

Rockville rocks.

October 30, 2015

Since hearing about it, I had been thinking about entering the Rockville Rockhopper Enduro that happens on Halloween day. I try to do a few races a year, just to keep honest. Recent years, that’s meant downhill, flow, and cyclocross. Finally an easy to attend enduro close to home. Typically, they are 4-12 hours of driving […]

2015 SuperPro JMP/Oakland CX

I had a great time this weekend at the SuperPro JMP/Oakland CX race. It might be my only cross race this season so it was nice not to be racing around in a junkyard parking lot. This was such a nice location. This was the first bike race (ever?) in the Joaquin Miller Park. We didn’t […]

1×11 speed chains

On a recent build, I used the new SRAM GX 1×11 drivetrain. It’s cheap and seems fairly solid. It’s not super light but it gives me a chance to use a proper 1×11 configuration in a situation that it could be an asset. I used a KMC X11L chain. I’ve been using KMC chains for […]

I went and hung out at the DFL race in Bayshore last night. Dirty cross racing in a toxic hell hole of a place. The Bayshore Train Yard is not a safe place for man or beast. Lots of flat tires on the course during the race and a few spills in the main corner but […]

Live fast, die young, or grow old trying.

Urban bikes are odd things. They have to do very particular things for each particular user. Grocery getters to cross town commuters. Fashion victims to bomb squads. They take on rolls like we all to, generally categorizable but highly individual. I ride all over the bay area while commuting but mainly through San Francisco. I like […]

Eyes on the prize

July 13, 2015

I did some work on finding a better scope position for my 223 bolt rifle. The scope was a bit far away from my cheek weld position. I brought it back about an inch and a half. It’s so much nicer now. Very relaxed and comfortable setting up with no straining or struggling. The base […]

I’ve been riding mountain bikes since about 1990. Before that I had spent a year or so as a bicycle messenger and before that a skateboarder (both in Boston). Mountain bikes were pretty mangy before the 90’s. They slowly evoved until the big advancement leap started around 2010. In 1990, I was hired at Fat […]

Bad engineering

Braking finesse

March 15, 2015

Setting up brakes on bicycles can sometimes be an exercise in utter frustration. Several factors contribute to setup issues. People will reuse poorly worn pads, use bent rotors, over fill resoviors and just mismatch parts. One issue most overlooked is the geometry of the caliper mount. Some people do take the time to machine the […]

Booming with the big boys

March 9, 2015

The time finally came (again) to have a big trail bike. This happens every now and then. The pendulum is always swinging. Sometimes you want to ride the 29er hardtail and sometimes the DH bike. Often, you want something in the middle…but what is that? After 14 months on the Anthem 27.5 (mod), I wanted […]

Late last October (2013), I had a pretty bad crash on my Yamaha Majesty Scooter. I was headed home from work around 5pm on Park Presidio in SF heading North to the bridge and then Marin. Just as I was passing Geary Boulevard, I was momentarily distracted and didn’t see traffic stopping short ahead of me […]

Garmin 510 case swap

May 12, 2014

Recently, I went to mount my Garmin Edge 510 to one of my bikes. It twisted in all wonky so I looked further. I must have broken a mounting tab from the back of my on a recent ride. I had to fix it. I use GPS data all the time to track my progress, routes, […]

Bike to work day 2014. Keeping it real in SF.

May 7, 2014

People have a lot of excuses. Excuses are one of the limitless resources I know. So many people craft and build lives that require a car then complain about having to use one as well as care and feed it. It’s silly. Build the life you want and find ways of keeping true to your heart. […]

11 Speed – The offroad.

April 16, 2014

This past week, at the Sea Otter Classic, Shimano officially unveiled their new premier off-road group-set. The XTR M9000. Attempting to directly compete and regain traction against SRAM’s now dominant XX1 group, the new Shimano group has eleven speeds and a single chainring option. There are some differences with how the rear derailleurs function. The […]

Sea Otter 2014. Jumping sharks with fat bikes.

April 14, 2014

I went down to Sea Otter again. I raced the downhill and spent most of my energy on practice and the race. I was able to get some time in the pits and booths for some pics. There are several things to mention. XTR Front Derailleur – Truly amazing. I’m a fan of 2X shifting […]

2014 Sea Otter DH Bike & Race

April 10, 2014

2014. It’s time for another Sea Otter Classic. It’s always such a great weekend and so much fun. If you’ve never gone and raced then you are really missing out. Don’t just go, race! It makes a difference. You become part of the show and it’s a whole different thing. The weather looks to be […]

NAHBS 2014, Charlotte

March 19, 2014

I love going to the North American Handmade Bicycle Show (NAHBS). Now in it’s tenth year, this show is an event where some of the most dedicated, inspired, and serious bicycle crafts people display and sell their work. Also, it’s a place where the geeks and aficionados can meet with the crafts people, to not […]

The fender and the mudguard

March 14, 2014

Due to the drought that we’ve been facing in California, this post is coming up a lot later in the season than I would have expected. We finally have a little bit of rain and the trails no longer resemble dry summertime conditions. The slippery dusty hard trails has been replaced by soft slop and […]

Engin Ti Road Dropout

March 4, 2014

This is something sweet that we’ll see at NAHBS. Drew Guldalian, of Engin Cycles, is one of the finest frambuilders in the United States. A 3 time winner of Best Mountain Bike prize at NAHBS. He’s, in my opinion, a framebuilder’s framebuilder. Like the folks at Firefly or Carl Strong, the work he does contributes […]

Bikes change. We change. Trails change.

March 2, 2014

Over the years and more subtly throughout the year, how your bike fits you and how you fit your bike will change. This change isn’t just the simple  bio-mechanical fit, but also how you relate to and use the bike. It is a commonly held myth in the cycling world that the ‘fit’ of a […]

Reverse engineering curves – The Sagitta

February 17, 2014

Here’s something fun and useful. I love when I get to get all math-y… A long time ago (2006), I put a blurb up on my wiki. It was a re-post from long ago that I had posted onto a skateboarding message board, probably back in 1998 or so. My web site, wiki, and now […]

The bird is down (or How a bike frame should fail)

February 14, 2014

I build bikes, I tune bikes, and I ride bikes. I design them to work just right and then I ride them and find out if they really do. As a constructor, I’m ensuring that what’s on the paper matches what gets painted but most importantly, that what get’s painted isn’t going to get somebody […]

Hadley Singlespeed hub

Skinny little bitch

February 8, 2014

I had some old Independent 101 mm skate trucks laying around and a set of wheels collecting dust. I figured I’d put them to work. An Indy 101 mm truck is very narrow. Typically, you’d be using side set wheels in a modern context to make these work for anything but a child’s board. I […]

The ‘guide’ ring.

February 7, 2014

Skinny cranks

January 17, 2014

Here’s one of my favorite new bike setups. Skinny multi-speed mountain bike cranks. XX1 cranks with two chainrings and a guide ring. This setup is  going on my Firefly 29er Hardtail and I just did it on my Anthem 27.5. I’ll have just 7mm of clearance from the fat Ti chainstays. Sick! Enough, I hope. I’ve been a Shimano guy […]

Hipster pants…or something like them.

January 14, 2014

I’ve got a real problem with hipsters. They completely lack authenticity but they are also compelled to blaze this into everyone’s faces and with such arrogance hidden beneath faux irony. Everything they do seems to be for show and they suck the life out of anything that was once cool. Then, when the corpse of the […]

Bean Can Top Tube Armor

December 27, 2013

Ever have a buddy destroy a fancy carbon frame in a crash for something as silly as the handlebars smashing the top tube. It’s an epidemic. Fuck that. For the past few years I’ve been struggling with fit on my mountain bikes. Even with my own designed bikes, I know where I want the grips to […]

Firefly Fe Road Dropouts

These went live today. So cool. It’s been interesting watching all of this unfold. A year or so ago, I designed a pair of titanium road dropouts for Firefly Bicycles. They turned out pretty good. Everyone was really stoked on how they looked and worked within the bike. Recently, Jamie contacted me about a pair […]

The Butcher revisited

November 19, 2013

The long term update. Three years ago, I put together a new Santa Cruz Butcher APP bike. I was looking for a super tough, cheap, simple play bike that I could do anything with. That turned out to be quite the learning curve for setting up longer travel trail bikes. The way that I initially put […]

Finishing the job right

October 31, 2013

There are right ways of doing a job and wrong. People talk about this a lot but somehow few really stick to it. Recently, while trying to solve some gearing issues, I ordered a custom chainring from Warhawk Industries. I wanted to get a 32t and 34t ring in 80BCD. I ordered the part with 2.5 […]

Spider attack!

I’m a Shimano fan. Some things about Shimano just can’t be argued; they make the best brakes, pedals, and cranks….PERIOD. I’m also a big fan of RockShox forks, Truvativ stems, posts, and bars. My big problem is that lately I’ve been buying SRAM cranks. Sorry, I do love Shimano cranks. Many years ago, Shimano introduced […]

Drilling holes in perfectly good bike frames

October 4, 2013

Things have been changing a lot with modern mountain bike specifications. Dropper posts, long front centers, cable routing, and 142mm rear spacing to name just a few things. When it comes to dropper posts, it’s settled that internal or ‘stealth’ routing is the standard and preferred way of doing things. Bike frames that are just a year or two […]

I’m not easily impressed when it comes to seeing bikes out in the wild.

Shadow+ short cage issues

The new Shadow+ clutch system is an incredible addition to an already incredible 10-speed drivetrain (Dyna-Sys). Originally, the 10-speed offroad shifting was better than any other off road system they’d produced to date. Light, precise shifts with the most rare of […]

Putting a skateboard together…properly

Tactical dog leash

August 19, 2012

I had a little sewing party in my kitchen on Friday night. I had two things to do; fix the strap on my messenger bag and make a neat dog leash thing. I was derailed from completing the strap as my ‘unsticher’ tool broke. So I put more energy into the leash. It was to […]

Weight loss of scooter tires due to wear.

August 17, 2012

I just changed out my insanly worn out tire from my 2001 Honda Reflex 250 scooter. It’s such an amazing commuting machine. I had to get it back up and running asap. Nothing can really match this thing for the job it does. I could live without my motorcycle but not my scooter. I decided […]

27.2 to 27.0 Seatpost Modification

August 15, 2012

My friend Donald Reni has a problem. He owns a Bridgestone bicycle. Other than that, he’s got another problem. This is supposed to be a shit bike. A shit bike is what I call a bicycle that you can ride and lock up around the city worry free. It’s not fancy, it’s not worth much, […]

The Zee short cage problem

August 11, 2012

Shimano has recently issued the new Zee line of parts. Essentially, Zee is just SLX for downhill and gravity bikes. Zee is a very nice line of parts and essentially makes up for the problems with the Saint line of parts – cost and weight. Don’t get me wrong. Saint is awesome. I use many […]

Bicycle gears

August 9, 2012

This post was inspired by a conversation that I had the other day when I bumped into my friend Cameron Falconer at Java Hut in Fairfax prior to the each of us leaving on a ride. I was on my neat Firefly 29″ bike and he was on his road bike. Somehow the discussion of gearing […]

Textiles are the new black.

July 28, 2012

To manage all the gear that goes to the range when I’m  shooting, I finally broke down and bought a proper range bag. I searched around and found that one of the most recommended bags is in fact one of the cheapest. The MidwayUSA Competition Range Bag ($44.99, #259680). I got one. It’s a fantastic […]

Dealing with a spare tube

July 23, 2012

Here’s a cool thing. I was having a discussion with Chris Ioakimedes this past Sunday. He had a tube in his pocket, still in the box. It turned out that we both usually leave them in the box so that they don’t get damaged. It seemed like such a bulky awkward way of dealing with this issue. […]

When I talk about a longboard…

July 20, 2012

When I talk about a long skateboard, I’m usually talking about something very different from what most people are talking about these days.   Let me first make a clarification. There is a longboard that is used in real skateboard racing, downhill and slalom. I’m not talking about competitive skateboards used in these specific racing […]

The hair trigger

July 11, 2012

Not really, just some fine tuning. This is my first real “cuttin’ metal” modification to my AR-15 platform. I’m playing with the stock trigger mechanism trying to make it work well. Similar to my work with motorcycles, I’m trying to focus on modifications and cash outlays that actually make a difference and return on the […]

The 2012 Rock Shox SID RLT on my new 29″ mountain bike needs tuning. Because of my injured hand, I’m really not hitting the front end as hard as usual and it’s resulting in a ride that is too harsh and not using all of the travel. I’m going to change the oil in it to a […]

The toy gun. Lot’s of bang for less.

July 6, 2012

The goal of putting this gun together was to ease my way into the AR-15 system while having a rifle that would be cheap to shoot a lot and usable at the local indoor range. A 22LR system is obviously the way to go here. I also wanted to keep the gun light as I […]

Gun tuning with springs and oil

Sorry Lorri

April 3, 2012

This is an apology to Lorri Lee Lown. I was wrong about something and insisted that I was right. I argued that the increased friction caused by heavier riders and the increased drag due to their larger size overcame the increased downward forces generated from gravitational pull compared to smaller lighter riders making the heavier slower.

SPRINGS…cause it’s spring!

March 31, 2012

Ask anybody that has studied physics about springs. They’ll tell you about Hooke’s Law, the linearity of coil springs, and brush them off as the most simple topic. They probably got great grades. Some of them probably got masters degrees or PhDs. The problem is is that they don’t know what they are talking about […]

It’s happened again… I joined up with the guys at Firefly Bicycles to get another dropout done. This time it’s for road bikes. Firefly makes a lot of extremely elegent and fast road bikes. The craftsmanship put into them is borderline obscene. The pride the owners of these bikes take is about the same. Any […]

You don’t know anything unless you’ve measured it…

You never know anything unless it’s been measured. That’s the rule any engineer lives by. Most people think of suspension systems and tuning them as some sort of voodoo or black art. The #1 problem with these folks is that they really never understood the role that springs play in the system or how springs work in a […]

Spring perch slippery shims.

March 9, 2012

When a spring in a shock is compressed two things happen; the spring twists and the spring cocks. When this happens, the spring needs the freedom to do this otherwise the restriction results in mechanical friction in the shock, slowing it down in an uncontrolled and unpredictable way. In motorsport, you would use a hydraulic […]

Headspace Shims!

February 23, 2012

I just made a few of these little dandys. They are shims that are placed within the split bolt of the Ruger 77/22 to adjust the chamber headspace. A 22LR firearm should be headspaced to the absolute minimum to get the most accuracy possible from the gun. Many guns will come with far too much […]

It’s a gun slightly more expensive than it’s competition, but it’s got a great reputation for use, it’s made in America, and it looks awesome. Plus, it’s super light […]

Today I stumbled on the proverbial pot of gold for bike folks, an early Wicked Fat Chance at a local pawn shop.  The bike apears to be a late 80’s or very early 90’s frame. It’s still got the pressed in BB bearings that were phased out in 1991. Honestly, I don’t need it but […]

“Adjustable suspension” by Fox

Sadly they were on cross bikes while I was on the mountain bike intent on trail riding. The ride – Tenderfoot: Cypress: 777: Gravity Car: Railroad Grade: West Point Inn: Railroad […]

Trails don’t suffer fools gladly.

August 5, 2010

I ride my mountain bike on single track trails. These trails, I keep assuming, are my friends. I spend time with them. I love them. I fix them when they are hurt. I work hard to keep a quality relationship with them. I forget to think about what the trail thinks about me. What does the […]

Riding the wrong bike.

July 26, 2010

Anybody that knows me will already know that I am the first to question a person’s equipment choice on a bike ride. I question actively, vocally, and (in my mind) friendly way. One major tenant of mine is that cyclocross bikes are stupid bikes. They excel in only two situations; cyclocross races and mixed terrain […]

Countries that suck!

July 23, 2010

#1 on my list is, of course, England. Top reason: BSC (60°) thread, special case, 13/32″ x 26 tpi. Let’s just call this the Sturmey-Archer thread from hell. It’s doesn’t conform to SAE, ISO, JIS, DIN or any other modern standard. It’s not even Whitworth (55°), which you might imagine. It’s a special case, used only by […]

Brooks Saddles?

July 21, 2010

What is up with Brooks saddles? 1. Heavy as hell – The lightest saddle that they make is the B15 Swallow Ti. 370 grams. Mind you that is the lightest one. Most of their line weighs in at 500 grams or more. Much more if it’s got springs on it. 2. Lame looks – Honestly […]

Cream Puff

July 18, 2010

The Pedal Panties party: The Pedal Panties girls threw an even on Union Street. It was fun. The best thing for me, not being their target audience, were the cream puffs. I love creampuffs.

The old school.

July 15, 2010

Anybody that knows me can attest to my hatred of the ‘old school’. I’m not talking about doing a massive front-side boneless one or a huge g-turn, a miami hopper or a simple ally oop. I’m talking about old school technology and peoples concepts that this garbage was somehow better than what we have today […]

Soil Saloon SF, 2010#2

July 9, 2010

Last night I went to the Soil Saloon race with Michelle at Golden Gate Park. http://soilsaloon.com/ What a great night and great event. The Soil Saloon folks really know how to host a really great time. Since I was again not racing (lamo!) and since Michelle decided not to ride a good bike to the […]

Two dogs.

July 7, 2010

Having one dog around is awesome. Two is even better. Here Maggie is posing with another dog at Stray Bar where we go for Smarty Pants Trivia Night on Tuesdays. There are usually at least 3 dogs on the scene and sometimes a few more. Later in the night a brown pitbull named Rufus showed […]

“Home is where the heart is.” It’s so true. Home is a place you know when you are there. I was feeling that this weekend on a mountain bike ride in Marin. I was on a section of singletrack waiting for the dog to catch up to me, just hanging out in the middle of […]

SF loves to close it’s streets!

July 5, 2010

One thing I love about San Francisco is that this city will close down a street or entire part of town for almost any reason. On any given weekend throughout the summer you will find several miles of “Closed for Party” road. This July 4th was the 2010 Filmore Jazz Festival. 12 solid blocks of […]

PVD Plustwentyfive Headset

July 4, 2010

I was helpping to prepare Max Houtzager’s Downieville All-Mountain race bike and we came upon a setup issue. A good fork for the race was 25mm shorter than the fork his 2010 Specialized Enduro Carbon was designed for. This created a major problem because as fast as Max is up and down the hill, he […]
