Product Story

When it comes to flat-mount brakes, perfect tolerances matter, and these adapters are as precise as it gets. That being said, we’ve slotted the mounting holes a  little, so you can adjust your caliper if need be. Mounting hardware included.

We also sell Rear Flat Mount Adapters HERE.

Since we’re bringing back framebuilding parts, w Since we’re bringing back framebuilding parts, we figured we may as well make another batch of Permanent Pivots. These elegant CNC machined stainless steel brake bosses allow you to remove the pivots from any PAUL rim brakes, and mount your brakes directly to the boss for a super clean, simple aesthetic. These have been very popular when framebuilders are designing a bike around Racer and Racer-M brakes, which would be locked into PAUL brakes anyways, but you can also use them for any of our Canti and V brakes. Available on the website now!
It’s been many years since we’ve offered these It’s been many years since we’ve offered these single-speed/track dropouts, but we now have a limited run of 100 pairs available for those of you building 10mm axle singlespeed/track frames. The knurled self-nesting adjusters and locknuts make it super easy to center your wheel and dial in chain tension, then put the wheel right back where it belongs after re-installing it. Available on our website now!
Big thanks to everybody that stopped by to see us Big thanks to everybody that stopped by to see us at @seaotterclassic! The #SierraTrailblazer will be at the @sierranevada gift shop in Chico until we bring it with us to the Wildflower Century, so take a peek if you’re in town. Don’t forget you can donate to win this wicked hardtail via the link in our bio until April 24th.
The #SierraTrailBlazer is done and on display at @ The #SierraTrailBlazer is done and on display at @seaotterclassic in the @sierranevada beer garden as we speak! Be sure to slide by for a 🍺, check out this wild bike 👀, say hi to our crew🫂, and learn how you can donate to win it (there’s also a link in our bio). The crackled (burned) paint job and shiny new “Pale Ale” green anodized components represent fire and new growth, a phoenix rising from the ashes of the Dixie Fire that burned 1 million acres in the northern Sierra. This ties into our fundraiser for @sierratrails who are revolutionizing a new method of integrating fire resiliency and community protection into their years of experience building and maintaining recreational trails in Northern California. Head over to @theradavist for full photos and a detailed breakdown of this ultimate #LostSierra hardtail!
Wait, is this an April Fools Day joke or not?! Is Wait, is this an April Fools Day joke or not?! Is Paul really weird enough to release square taper cranks in 2025? Yup, our classic 100% Pure Cranks are back, but this time with self-extracting crankbolts, 3-Bolt Direct Mount chainring interface, and JIS square-taper bottom bracket compatibility. These are machined from super strong American milled 2024 aluminum, which means we can remove a lot of material for an elegant crankarm, without sacrificing strength and stiffness. The square taper bottom bracket interface means you can fine-tune your chainstay clearance, while the 3-Bolt direct-mount chainring means you can choose from a wide range of brands, teeth, and offsets, for a combination of killer Q-Factor and chainline. Available on our website or from your favorite local bike shop now! (Unless this is actually an April Fools Day Joke, I’m still not sure.)

Battery-free reliability might be a good idea when you’re waaaay out in the Lost Sierra…? I know, this is a HOTLY debated topic, let’s keep it civil in the comments, ok?!
