Sticky Pedals

by

I’ve been working with the HT AE05 pedals lately. I just upgraded the pins. Now I’m looking at the spin. Out of the box, these pedals are very bound up. They have an insane amount of resistance to them. I wanted to figure out how to improve that. These are simple bushing pedals with a … Read more

Downgrading the shifter

by

I’ve made it clear that I’m not a fan of the new SRAM Transmission system. I’ve found that it shifts very poorly. It’s painfully slow. The shifter ergonomics are terrible. There’s no clearance under the new stealth master cylinder reservoirs for a better clamp. And the shifter pod perch is very weak. That’s a lot … Read more

Finders Keepers

by

finders, keepers; losers, weepers I have a several general rules that I follow when I’m riding trail. One of them (and the topic today) is that I stop to pick up any small parts that I see on the ground. Even if they are fairly beat or weathered. I do that. Why? The logic is … Read more

HT AE05 Pins

by

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

All-Road Upgrades

by

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

Trannies

by

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

Numerical Suspension Modeling

by

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

The Adam Prosise Interview

by

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

The PVD Mount

by

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

T47 Shim Rings

by

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

PVD-RSD SRAM 8-Bolt Spider

by

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

2023 PVD Northrop M2-F2 All-Road

by

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

Permeable Prints

by

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

Plastic Printed Tube Blocks

by

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

2023 MADE Show – The Chris King Party

by

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

2023 MADE Show in Portland

by

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

Narrow Cranks for the Stumpjumper

by

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

Bingham’s New Shop!

by

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

PVD FM to PM Adapter

by

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

142mm MTB is back!

by

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
