I said in the last post that I was going to be making some nicer pins for my new HT AE05 pedals. These were made from stainless steel M4x8 set screws. A basic 4mm x 34.7 degree taper. Sets up for a nice 1.5mm tip. The performance gain here is that it is now a … Read more
Yesterday, I made a couple of changes to my all-road bike, the 2023 PVD M2-F2. I figure that both of them were worthy of comment as this is always a work in progress. The all-road platform is fairly exciting for me to work with. The ‘answer’ to the puzzle is relatively undefined in the bike … Read more
Back on November 2, 2023, Transition bikes dropped their new hardtail bike, the TransAM. This is a bike carrying a name that they’ve used for hardtail models many times in the past. While I try to keep up with comments on some of the more interesting products that come onto the market, I just didn’t … Read more
I’m probably known best these days for my hardtail mountain and all-road bikes. What some may not know is that I have a long history riding and tuning suspension bikes and sport motorcycle. I’ve had big enduro bikes and downhill bikes. I’ve changed shims, fluid, and springs to alter the performance of these systems. This … Read more
This is a project that I had been working on last year. It’s a fixturable sine bar for use on fixturable fabrication tables. Sadly, I got distracted before finishing it but it might be at some point. For that reason, I delayed posting on it until now. With a good design and an hour at … Read more
There’s a funny thing in the world of fixturing. Most of the pin holes on the smaller side of the range for metalworking rasters are 5/8″ or 16mm. In the wood working world, they use 3/4″. This is frustrating as there are some nice products that would work fine for some light duty work. So, … Read more
Last week I posted here about the new bicycle frame fixture (Samantha) that I’ve been designing and am hoping to produce. I mentioned that I was wanting to produce a fork fixture that fits in with the rest of the ecosystem. Well, in the interest of economy and ensuring that any extended considerations of the … Read more
The skate truck project continues to move forward in the background of the other big projects and developments. Nothing ever stops. Movement is important. Initial designs for the G6 started almost as the G5 trucks got finished. I had a lot of ideas that I wanted to get ‘on paper’ when I was setting them … Read more
2024-10-25 update is HERE Thanks to our evolutionary push to modern bike design, back in mid-2020 I brought the PVD Cyberdyne bicycle frame fixture into the world. Since, I produced designs for the SKYNET (2021) and WOPR (2022) frame fixtures. Now, in 2023, we have the big update. Samantha !! The first 3 fixture designs … Read more
I can’t remember exactly when Adam Prosise first showed up on my radar. It was maybe 4 or 5 years ago. I’m not sure. It was clear that he was something else. Adam really stands out in a crowd, literally and figuratively. He’s tall, 6’4″. He’s excited. He’s in the game. Chances are, you may … Read more
In my effort to make some video content, I decided to share some discussion on frame fixture design and development. I need to figure out a way to produce this kind of content without having to do too much (or any) editing. I figured some things out on this run of videos. I need to … Read more
Last night I got a call from Ronen. He was finally getting around to mounting post mount calipers to his all-road bike. We have special conditions in Marin and the way Ronen and I use our all-road bikes push lightweight flat mount caliper brakes to their limit. Since I’m old and fat, I made the … Read more
I’ve decided to share a couple of my dimensioning templates for others to use. I’m thinking that this can move some others forward in an easy way. One of the more powerful components within BikeCAD Pro are the templates that a user is able to construct, save, and share. Custom title blocks, notes, paint schemes, … Read more
It was time to take another look at a ‘problem’ long in the making. Holding crap to a bicycle frame. In the bicycle world, we’ve been using a system to hold water bottles to a bicycle developed sometime in the 1930’s(?). Little has been done since. A hole is drilled in the tube and threaded … Read more
These are hard to get items. I wish that that wasn’t the case because they are very important. Few discuss them. In this case, these are 50mm x 47mm x 1mm stainless steel shims for T47 bottom brackets. I need to get a few 0.5mm as I needed one today. Broad strokes still work and … Read more
Mountain bikes and all-road bikes are some of the harder bikes to design and build. Squeezing frame members around tires and drivetrain parts compound into many other problems to solve. One of the primary ways of alleviating this is to provide as much clearance on the outside of the bike as can be made. This … Read more
Better. Stronger. Faster. I had two heroes when I was very young child. Mohamed Ali and Steve Austin. Ali was amazing. Steve ‘was’ an astronaut and more. It’s been quite a while since I’ve been able to put serious development time into the all-road platform. It was mid-2021 when the majority of the work on … Read more
I’ve discussed (2) some of the particularities in additive metal manufactured parts in my bikes and skateboard designs. It’s strange stuff. Since it isn’t (in a macro sense) a uniform homogeneous crystalline structure, it has some strange failure properties. It’s globular. I think of it like Styrofoam. It’s quite stiff and strong but when it … Read more
In a way, one of the nice things about additive manufacturing is the long wait to get the parts. We don’t really like that wait but it’s a fact and hard to change. It takes between 20 and 30 days to get my parts from the printer from when I send off the models. Since … Read more
This is some seriously nerdy stuff. Since I haven’t seen any folks discuss it so, once again, I have to. I’ve just sent files to the printer for a new all-road bike for me. After most of the real work had been done, I began fine tuning and evaluating my expectations and decisions. This last … Read more
This was the MET Gala of the framebuilding world. I’ve been to a lot of parties at these shows, this was something else and the best yet. Everyone was there. The place was PACKED and HYPED! A few weeks before the show, the MADE organizers let us know about a couple of industry parties that … Read more
The 2023 MADE Bike Show in Portland, Oregon this past week was set to be quite an event. Announced about a year ahead, people seemed to be getting more and more amped as the date approached. In the weeks prior, the socials buzzed with hype and excitement. Everyone was getting ready and had something special … Read more
This is a quick one while I’m busy modeling the new bike and about to head up to Oregon to do some press at the MADE show. Back when we were assembling Windy’s Stumpjumper one year ago, there was one detail that I didn’t address. It was the Q172 Shimano FC-7100 SLX 170mm cranks. While … Read more
Colorado road trips are pretty great! Last year we rode at Trestle Bike Park and this year we got to ride Keystone Bike Park. I was stoked for this as most folks I talked to agreed that Keystone was the gnarlier of the two. That proved to be quite true, it’s an awesome hill. As … Read more
This is an exciting new tool for me and worth taking a look at if you build bike frames! I’ve been needing this tool since I started building my own bikes. I probably could have even used it before that. I finally got around to designing and producing it. I’m sure that many others will … Read more
Warning! Some of the information below has been superseded by new information. This was the last detail that needed to be sorted for the PVD Millennium Falcon build. I had left the rear brake adapter to the end of the project as I figured that I had something to work. I hadn’t . Little details … Read more
Ronen and I were discussing some details for a few of his upcoming frame building projects. He is fresh off a success in building (almost) 100% of his new Raven Caw in his own workshop. Like the Sith (see: Rule of Two), he has the twin to my Cyberdyne frame fixture. He’s just got a … Read more
Windy and I were on the road. We were cutting through southern Utah on our way to the front range. We had to decide if we were going to go through Gunnison or Durango on the way to Salida before going north. I enjoy Durango and it’s generally a good stop and we chose to … Read more
While everyone is learning how to work with the new SRAM Transmission Drivetrain, issues arise. The trim adjustment needs to include a wider range for some reason. It’s too narrow, even when using parts within spec. Don’t ignore the high torque that is put on the mounting screw for the derailleur. 35 Nm (310 in-lb, … Read more
Every time I build a bicycle, I try to take something (or many things) to a higher level. I didn’t see a detail until after I got my recent bike, the Millennium Falcon, back from paint. I wish that I had thought of it in time. I had decided to add some reinforcement washers under … Read more
