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 … Read more
What Happens when you put mineral oil (HSMO) in a set of brakes designed for DOT fluid? A lot of people have been talking about how nice the new SRAM Guide brakes are. About how these quad-piston brakes seem to work almost as well as Shimano twin-piston brakes. For years, Avid and SRAM brakes were some … Read more
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, … Read more
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 … Read more
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 … Read more
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. … Read more
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 … Read more
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 … Read more
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. … Read more
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. (The image below shows a post mount pad set vs a flat mount pad set) F03C (Y8J79802A) used to be the metal-type pad used in the calipers. Now, J04C (Y8LW98030) is … Read more
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, … Read more
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. … Read more
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 … Read more
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. I don’t ride at Rockville very often and this gave me a great excuse. Surprisingly, it came out that I had won my class and … Read more
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 … Read more
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 … Read more
I got a new camera chassis this weekend so Ronen and I did some shots on Saturday. A nice little trail in Marin. Great for photo practice. I got a Canon 7D Mark II. It’s supposed to be amazing and it seems that way. I need to get a lot better at taking photos to … Read more
I went to the Access 4 Bikes member appreciation party yesterday hosted by City Cycle in Corte Madera. A nice event with lots of beer and great tacos. Plenty of talk about singletrack and who’s keeping bikes off them. Here are some photos that I took. Just snapping folks. I got a little demotivated when I … Read more
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 … Read more
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 … Read more
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 … Read more
***9/4/2015*** Parts sold by Nova Supply have been corrected and no longer have this problem. I probably should have posted this back in mid April when I found this. I was giving some folks time to react. Time ran out today. The Allotec C-43-1 142×12 DT modular dropouts are being used by more and more people … Read more
I’m a pretty dumb guy. Really. I learn new things every day that make me step back and say, “Dam Pete! You’re a dumb mutherfucker! You should have seen that long ago. It’s obvious.” I get kinda down sometimes. I feel like I’ll never catch up to what’s going on. I have to try and … Read more
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 … Read more
Recently, I got some military tape, embroidered nameplate material (militarynames.com) for some fun stuff. Some velcro name tape was for my two bags that have 6″ velcro locations & some simple sew-on name tape for other items. The sew-on tape is very cheap so I could get a few of them for very little. Here, … Read more
The second annual Tamarancho Endor Flow Trail Chainless race is in the books. The race is a part of Bike Monkey’s Tamarancho Dirt Classic weekend. Last year’s race was super fun, amazing, challenging, and a thrill. It was the first legal gravity race in Marin County since the last Repack race in 1984. Major props! This … Read more
Years ago, at an early Maker Faire in San Mateo, I was lucky enough to see and touch an early test mule and prototype for what is now the Lit Motors C1 vehicle. It was so cool. It had gyros and batteries and computers and sensors. It balanced on it’s own and corrected itself when … Read more
***Warning: This post involves me spewing hatred*** Fashion is a terrible thing sometimes. Some people want to own bikes like you get from yard sales or from the dump and claim it to be the greatest thing since sliced bread. It seems to be a thing and people will pay a lot of money to … Read more
Two years ago, the Endor Flow trail at Camp Tamarancho was finished and heralded one of the biggest changes in mountain biking for our area that I’ve seen. In the two years following the ribbon cutting, local riders and riders around the country have been demanding simple to ride, smooth trail free of any rocks, … Read more
