Today is my day to eat some crow. Attentive readers will know of my work on brake caliper mount locations and a tool for attaching flat mount caliper bosses in the correct location. I’ve been pretty proud of this work. It cleans up a big mess. Devin Bodony of Lichen Precision, a machinist bro that … Read more
More photo stuff… With Canon’s release (Fucking finally) of a DSLR driver for webcam use in the age of COVID-19, we have entirely new practical uses for photo gear. Quality webcam use has become very important to looking professional. You should put some thought into this. Good lighting is important. Some headphones. A decent background. … Read more
After all the drama of the winter injury season has subsided and the lazy days of COVID-19 are here, I finally got back to the fork test video that I had intended to do on the day I broke my clavicle….and then big toe. Originally, I had intended to do this filming with a GoPro … Read more

That’s right. Pimpin’ ain’t easy. I try to look very closely at all aspects of my riding. That’s not restricted to my bike or the trails that I’m on but also what I’m wearing. Anything can be optimized! What do you need? Make that happen. I’ve talked in the past about the need to cut … Read more
In photography and filmmaking, the joke is often made that “it can be fixed in post” to justify doing very low quality work. It’s true that there are a several small issues that can be fixed after the image has been captured. Some colors can be shifted, a smudge removed, subtle white balance changes, the … Read more
This came up in a discussion the other day. I figured that I’d bring it up here as it is current in what I’ve done in a recent design. I’ve been working with my klunker platform enthusiastically and have just produced the Supermarine Spitfire which was building on the Sopwith Camel. It makes use of … Read more
Here we are, well into 2020. The bike industry has just two products to sell: ebikes and all-road bikes. Nothing else matters. Those are the money makers and all that folks are really paying attention to. Everybody is trying to stake a claim. On February 15th, I saw a few images on someone’s Instagram that … Read more
Just touching base on what has been keeping me busy recently. After the Supermarine Spitfire crash, I took a deeper look at the materials that I use in my handlebars. A greater safety factor was needed at the cost of a little bit of flex. Some of these bars have been in service for next … Read more
This is an important thing for novice modelers and designers to think about. It’s tied up in this example. While drawing up a tool I was thinking of making, I chose to give it a knurl as it was a handle and that is what you do. Knurls provide grip. We see them all around … Read more
Here’s a problem some may have come across when setting up a high performance bike. It’s a little tricky. I needed to actuate a OneUp dropper post using an older style BikeYoke Triggy lever that used the 4.3mm (diameter) x 4.4mm (long) derailleur cable end at the lever. Typically, for this seatpost, we will clamp … Read more
Supermarine Spitfire. Today is new bike day. I try to raise my bar when I build a new bike. Each has to be an improvement on the past. Better, faster, funner. Whatever it takes just push farther. Maximize, minimize, optimize. There’s so much room for development. This is another next level bike where few see … Read more
The current trend in bicycle marketing is to talk about frame reach, the horizontal distance from the bottom bracket axis to the center of the top of the headtube. The ‘long’ in long/low/slack is for “longer reach” or “longer top tube”. Although this is just flagging that they don’t understand much about what they are … Read more
It was Thanksgiving a few days ago. Thanksgiving is one of only a few real holidays in the United States and it’s probably the most important. Important, as it’s not about turkey or shopping or even your crazy aunt and uncle. It’s about gratitude and that’s some good shit. I always try to focus on … Read more
POST: 2020/02/15 – An attempt has been made to refine the content you see here in a newer post. This should help a bit as it is clearer and more straightforward. Last year, PinkBike published an article describing Lee McCormack’s concept of fitting bikes using his Rider Area Distance (LLB-RAD) method of bike fitting. McCormack … Read more
It’s time for the Philadelphia Bike Expo! I wanted to be there this year but lots of important work got in the way. The design for this tool was done a couple of weeks ago. The tool was supposed to be finished before PBE and show to folks in real life but thanks to late … Read more
Generally, I like the motto “Move fast and break things.” It’s punk rock. It’s what tech needs to do. It pushes hard, fearlessly. It’s better to take the risk now than just pudder along doing the same old thing. Move the ball forward! This, except when things do get broke…and it took forever to do … Read more
I got these new brakes from the UK just before a hard BREXIT hit on Halloween. What an insane situation for a trade company. Spooky AF. #thanksobama The moving target that is mountain bikes never fails to disappoint. Everything has changed and will again. We can’t rest. Generally, things keep getting better. I’ve been saying … Read more
At Eurobike a few weeks ago, SRAM made public their Universal derailleur hanger (UDH) concept. There was a bit of hype from the marketing shills. None of it made much sense. The problems that all of the marketing people were saying it solved really aren’t legitimate problems or serious consumer problems. I didn’t think much … Read more
I use alloy nipples when I build mountain bike wheels for myself. It’s a real weight savings right where light weight really counts. They’re really the only choice for performance use. But, they break and you fix them. Your wheels are light. Simple. Over the years, I’ve learned a few tricks… It’s the details that … Read more
I had an issue a few weeks ago that I’m getting around to talk about just now. There’s a reason for that. It’s because I now have the part that I need for my all-road bike to work again….and this is bullshit. I had a pretty good crash a few weeks ago. Bad for my … Read more
侘寂. Imperfection is sometimes a strange kind of perfection. We’ll see a hot rod, motorcycle, or bicycle and it is such a terrible thing in the details but in that, it’s fantastic. Producing something like that takes time, wisdom, and a little bit of luck. Knowing just what blemishes bring out the soul of something … Read more
Every cyclist has to to fix a flat tire. For that, there’s IRON! Not all tire irons are the same. Most are terrible. I’ve been handling these things for a pretty long time. Every now and then you find some that just work well. In the bicycle world, tire levers (irons or spoons) are treated … Read more
A couple weeks ago, I was at an event mingling with many notable California bicycle frame builders and part designers in the custom frame building community. It was a great event where we did a lot of talking about the work of one man. He will be missed. One of these conversations was with a … Read more
I recently needed to remove a fussy T25 drive screw from a SRAM XX1 crank. Despite both the screw and tool looking in good shape, the tool kept camming out of play, rounding edges, and was turning into a terrible situation. I didn’t understand why this was happening but it was time for evasive action. … Read more
This may not seem like much but it’s pretty exciting for me. Bending tubes is an important part of making things out of metal. Everyone that works with metal needs a bender of some sort or is looking to find one. I’ve had one for a long time, an old DiAcro #4 but because of … Read more
I’ve been pestering people and challenging them to make a proper bi-plane bar for the past year or so. We need these for progressive all-road geometries. Nobody understands, blank looks were all I got. I wanted the carbon guys to step up but it was too much for them. I was forced to do it … Read more
“It’s tough to make predictions, especially about the future.” ― Yogi Berra My projects are going to slow down a bit. I’ve gotten pretty busy with a lot of summer duties. I have a bender cart in the works and a few little things going. Still, I wanted to post a few projects that have … Read more
