Fixed Disk Word

We kept getting requests, so we brought back the fixed-gear version of our Disk WORD hub. This unicorn enables the fixed-gear conversion of bikes with 135mm or 142mm rear spacing. It’s machined with care by us here in Chico, California. It’s absolutely bomb-proof, light, easily adjustable, serviceable, and comes with our own thick stainless steel lockring.

$216.00 – $241.50

Product Story

We machine these hubs from 2-5/8″ round bars of aircraft grade 6061 aluminum. The hub shells are put through four different machining processes before they go to finishing, and the end result is something we’re very proud of. The flanges are canted towards the rim, and the spoke holes are chamfered to reduce stress on the head and elbow of the spoke.

The hub shell is available with dedicated fixed gear and lockring threading on one side, with a 6 bolt disc rotor mount on the other side. Proper left-handed lockring threading keeps fixed gear cogs secure, and our heavy-duty stainless steel lockring is included.

The axle is precision turned in-house from 7075 aluminum, which has a great strength to weight ratio.

We use high-fill sealed bearings, and they can be easily adjusted with our simple adjuster ring.

Introducing the BËP. It’s just a handlebar plug Introducing the BËP. It’s just a handlebar plug, right? Sure, but when the machinist bike nerds at PAUL start 
designing, prototyping, (obsessing), and testing a project, even a simple bar plug can end up at 
NASA-level standards of tolerance, function, and reliability. 
We think we’ve arrived at the highest quality handlebar plugs in the world. Cheap rubber and 
plastic construction were never good enough. 100% CNC machined aluminum expanding-
wedge construction means that once tightened properly, they’re NEVER falling out or coming 
loose.

New bike camping froggy shirts and they are SUPER New bike camping froggy shirts and they are SUPER soft high quality US made 100% cotton, garment-dyed using a vintage pigment-dye process, then printed using a water based ink, so even the the ink itself has a soft touch and is breathable. So stoked on this artwork by @hurrydive and this might be the nicest t-shirt we’ve ever used. 🤌
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!
