Dutch Masters

I’m not a hipster. Really. I hope not. Anyway, I came across this thing on Craigslist the other day. A De FietsFabriek Bakfiets Classic dutch cargo bike. The ad explained the big problem. It had a broken kingpin but the rest of the bike was otherwise all there. A fix had been attempted that had failed … Read more

Scott Parsley vs the World

I know folks all over and going way back. Social media lets me see some of the cool stuff they do. Every now and then I see something they think up and I’m force to face palm myself. Obvious simple solutions that nobody sees until someone does. A month or so ago, Scott Parsley from … Read more

Enerpac for less

Everyone would love to own a full set of Enerpac hydraulic tools. For any mortal, that’s not going to happen. I’m lucky. I have an Enerpac A258 bech press, RC1010 cyclinder, and P392 2-speed hand pump. I’ve wanted to build on this for years but didn’t need or want expensive parts for cheap tasks. Everyone … Read more

GX-OGLE

You may know who Joshua Ogle is. He’s a pretty well known guy from the US bike making scene as he’s been making things for a very long time. One of the reference personalities for sure. Jericho Bikes (long since gone) is what he may be best known for when he was building frames in … Read more

Going faster…with mirrors

Going faster on a motorcycle is an interesting proposition because we need to also talk about when and where we are going faster. As a commuter in the traffic rich San Francisco Bay Area, my speed lane-splitting is very important to me as I spend an awful amount of time in that state. The CTX700 … Read more

The PVD Juvenile Skateboard

I’ve done a lot with skateboards over the years. More than most. With the addition of a pair of sisters, ages 4 and 5, in our household I had a new project. A skateboard for a child. Many would say, aren’t all skateboards for children? No. Most skateboards in the market are sized for 17 … Read more

GXP Helicoil

Under normal circumstances most folks wouldn’t bother with such a repair. They would just throw these cranks away. This isn’t one of those circumstances. This is different. I also don’t like to waste money and know exactly what I want. This part will be repaired. (I also like good content here) I have a couple … Read more

That tool you’ve wanted for about 35 years.

You know how you’ve been doing something for a long time? Like, a really, really long time. I’ve been doing skateboards for that long. I’ve wanted a tool since I started. I finally made it. It’s a drilling fixture for baseplate holes in skate decks. I’ve actually needed this several times in the past few … Read more

CTX700 Shock Swap

The Honda CTX700 is a pretty awesome bike. I fall in love with it a little more every time I ride it. Still, it has issues. The rear suspension being one of the more glaring. Why is it so bad? A few reasons; it’s a lower priced bike, it suffers under Honda’s “we did it … Read more

CTX700 Small Bits

I’ve been picking away at making my CTX700 the bike it can be. Here are some of the updates on that. Gearing: I have been riding the 15/41 gearing on the bike for quite a while now. It’s great. The bike now gets up and gets down to business on the Northern California back roads. … Read more

PVD 41 to 56 cone

Here’s a cool tool. It’s a replacement #745 Radial Centering Cone on the Park Tool #HTR-HS Head Tube Reaming and Facing Handle. It more optimizes use of the tool for bores from 41mm to 56mm without the need for a Park Tool # 750.2 Oversized Centering Cone Adapter (which doesn’t actually come up to a 56mm … Read more

I don’t make bicycles. I make weapons systems.

NOTE: This bike was updated in 2020. See post HERE. This bike was yet another journey into the creative pain cave. It was not something I had wanted to do. It was something I had to do. The war must be fought and we need the best tools. This is the magic bullet that goes … Read more

Wonder Woman

Some bikes can stop a whole show. At Interbike 2018, the annual US bicycle trade show, that’s exactly what this one did. Over and over you’d hear, “Did you see the Wonder Woman bike?”, “Did you…?” No other bike got more attention. It was an amazing piece of work by Nick Lee Airbrushing. The quality … Read more

Old man bikes

It’s time for my entry into the world of old man bikes. The sport bike kid has grown old. Still riding, just differently. I commute by motorcycle/maxi to San Francisco about 4 days per week these days. About 20 minutes on the highway and 25 minutes in real traffic. Highway in the afternoons is all … Read more

Bird of Prey flat bar

It was time to really test the Bird of Prey on dirt and in a more aggressive urban sense. Just a few mountain bike rides on it. Hopefully another few before it gets road tires for getting to work. Enough time for a general fit and gearing. 36t gear and 10-50 gearing to keep it … Read more

Krunk

The PVD Red Baron has long been the king of all the klunkers. Krunker. The dankest and rawest bitch in town. The bike isn’t a rehashing of old aesthetics. It’s a real modern ‘low’ performance bike. It flys down trail and feels good doing it. The original build was intended as an experiment on what … Read more

How to understand race results

Ok. The winner is the winner and second place is the first loser. We learned that a long time ago. Have you looked any deeper into your race results? Were you actually “mid-pack”? A top rider? Shitty? Sure, you can see what order you came in but knowing more about the race isn’t often discussed. … Read more

Keep it radio

On August 1, 1981, a brand new cable station, MTV, aired the first of many music videos in it’s programming. They were to be the first 24/7 music television station. They weren’t the first to air music videos to homes but they were the first that claimed to be all about music and their accompanying video … Read more

Never make when you can buy

The general rule in the machine shop is to never make when you can buy. With some exceptions, you’re usually doing yourself a huge disservice by choosing to make something that is otherwise available commercially at reasonable prices. There are some exceptions to this but often you’ll end up spending more money than it would … Read more

In defense of quick releases.

I’m not a big fan of the recent trend of tooled axles in all bikes. It has a place, but most of the time it’s a nuisance. They look clean. They are slightly lighter. But that’s really not everything when it comes to the use value of a bicycle. In real use most road going … Read more

Staggered rim drilling

Now that I’m back from my Whistler trip and ready to replace the brutalized rim of the rear wheel on my bike, I’m looking into the spoke lengths needed to do the job. The Chromag BA30 rim has a nipple stagger of about 5.2mm, 2.6mm to either side. This threw a wrench into my usual … Read more

What is this that we’ve become?

Here’s the question: Do you need a downhill bike? In other words, have enduro bikes progressed to the point of usurping their larger brothers? About fifteen years ago, if you were going to ride at a properly set up bike in a park like Whistler or Northstar, you’d have to be on a real downhill … Read more

Flat Mount Centerlock Issues

There’s an issue that the modern bicycle mechanic needs to address; When working with flat mount calipers and centerlock rotors and 12mm axles, a MTB large spline lockring can’t be used as they cause interference with the caliper or brackets with many front forks and adapters. The more streamline type are used. Instead of the … Read more

Super Deluxe Re-valve

In my RockShox Super Deluxe RT w/Remote Trunnion shock (205 x 60mm. Trunnion/8×30) in my 2018 Kona Process 153 29 DL/AL, I felt I needed more compression damping. I’d constantly blow through all my travel when big trail riding. That left nothing in reserve for DH riding. With a trip to Whistler coming up and … Read more

2018 PVD Bird of Prey

It has been a little slow posting here in PVD land. Not because nothing has been going on. Exactly the opposite. So much that my head is spinning. A new bike. All-road 3.0. This bike has been the largest scale bike project that I’ve done in a while. So many details to be designed, engineered, … Read more

Disc brake mounting systems

Warning! Some of the information below has been superseded by new information.  I’ve been doing a ton of work with disc brake standards lately. For my own new bike and because recent proposed “standards” needed correction. This post is intended to pass on what I’ve come up with and communicate to the industry a path … Read more

PVD FM140 Variant

Warning! Some of the information below has been superseded by new information.  Here’s another post in the never ending saga of the new FM140 mount I’ve been working on. I decided to go with a special variant to work better with SRAM calipers. SRAM calipers are shifted about 0.3mm outboard. Along with some manufacturing and … Read more
