Talking with another framebuilder bro today. He seemed to not know about 110×12 hubs and axles for the front of narrow gauge bikes. I got a little bit mad. Everyone should know. The market is currently flooded with fancy 100×12 wheels and exotic forks for road and gravel bikes. Cheap and expensive bikes are the … Read more100×12 should never have existed

The winter time in Northern California is a great time to really visualize the pathetic tuning skills of most mountain bikers and roadies in the dirt. Regular rain and winter storms cover the ground with water and mud. This extends for 3-4 months. It’s painfully obvious as each rider goes by, on the wet and … Read moreReal Fenders

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 moreDutch Masters

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 moreScott Parsley vs the World

This post is about something few people hear but many need to. You are not an expert on bikes. You aren’t. No matter what you’ve convinced yourself, you’re not. Recently, in a discussion on a bicycle frame-builder Facebook group, a common thing happened. A guy named ‘Timm Sima’ (?) started commenting within a thread. This … Read moreActually, you’re not a bike expert

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 moreEnerpac for less

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 moreGX-OGLE

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 moreThe PVD Juvenile Skateboard

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 moreGXP Helicoil

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 moreCTX700 Shock Swap

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 moreCTX700 Small Bits

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 morePVD 41 to 56 cone

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 around corners. Now, it’s inspiring further exploration in design. This … Read moreI don’t make bicycles. I make weapons systems.

My new CTX700DE has proven to be a pretty awesome motorcycle. It’s super comfortable, easy, and fun to ride. It even takes the hard roads well thanks to the super low center of gravity. I’ve been slowly fixing the various problems with the bike and tuning what is good. One of the most glaring problems … Read moreThe second most important part of the suspension system

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 moreWonder Woman

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 moreBird of Prey flat bar

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 moreKrunk

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 moreHow to understand race results

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 moreKeep it radio

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 moreNever make when you can buy

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 moreIn defense of quick releases.

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 moreStaggered rim drilling

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 moreWhat is this that we’ve become?

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 moreFlat Mount Centerlock Issues

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 moreSuper Deluxe Re-valve

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 more2018 PVD Bird of Prey

Warning! The dimensions that I present here still need final testing. There may be some configurations that are challenged. This is true in the current market and the problems that exist now do carry through to what I’m proposing.  I’ve been doing a ton of work with disc brake standards lately. For my own new … Read moreDisc brake mounting systems
