Never let making brakes get in the way of a nice Chianti

Thread revival : TPU test report for the 3D print nerds amongst us. Bambu's 'TPU for AMS' is really good. 68d, shiny and slippery like PLA but with some 'squish', you can control that with walls and infill too. I like 5 walls, 40% infill. But don't use that earlier model I shared for TPU, New version distributes the loads better on the softer material. I'll share v3 on makerworld when I remember to take some photos.

Whistler parking lot 1 reporting in - I just saw @Jason_Schroeder roll past on a very production looking norco DH race bike 🤘

Why? do you not like the unwanted attention?

Don't just base sizing off of XL vs XXL as a lot can be just marketing. When you cross reference geo charts, you'll find XL's from some brands that are bigger than XXL's from other brands.

Commencal quietly dropped the Tempo "V2" with the only revision being they got rid of the headset cable routing. (praise be!)

To make that XL Trek 32" fit me, I'd need about an 80mm positive stem and 50mm riser bars. I know there aren't that many people who are 6'6"+, but surely there are more of them than there are 5'2" people who would actually buy that bike, right?

The link loaded for a second but I can't access it anymore. Man, that thing was hideous. I love the chainstay length but they can keep everything else, especially the 32s. Give us that f/r ratio on a 29er!

I would love to see their kinematic charts for that one. It looks like it is pretty low leverage, 55mm stroke for 135mm of travel, 2.4 average leverage rate

Respectfully, the mass grave that I've filled over the years with cooked brake pads and rotors, broken rear wheels, and punctured tires and inner tubes from riding steep trails tells me that my center of mass has a much stronger relationship with my rear wheel than what you've depicted in that free body diagram. The main difference being bumps and holes. as opposed to the endless monochromatic smooth grade that's implied by the instantaneous snapshot of your freebody diagram.
