Product Story

This is the latest version of the very first single-speed specific MTB hub ever produced by us back in 1996. “W.O.R.D.” stood for Wacky One Speed Rear Device, because at a time when most riders had just upgraded from 7 to 8 speeds, the idea of stripping all the derailleurs off of your bike to make a super simple, reliable, harder-to-ride bike seemed like a pretty stubborn and a little crazy idea. Since then it has become a cult classic. This particular version has a wider hubshell to take advantage of 148mm BOOST spacing.

Yes, this hub spins very smoothly due to extremely high tolerance machined bearing bores (.0002″, that’s 8 times thinner than a human hair!) and high quality user-adjustable sealed cartridge bearings. The hub shell design has been refined over years of production and real world abuse to be as light as possible while still withstanding the abuse that the biggest, most reckless riders can put it through.

One of the best things about the latest iteration might be the super-stiff, super-light, flex-free, 7075 Alloy axle. It passes from dropout to dropout (unlike the flexy, non-adjustable caps so common on cheaper hubs that love to pop off and roll under your car or workbench every time you take your wheel off).

Fresh bearings are available for hub overhauls and rebuilds in the Hub Service Parts section. Please note, the axle kits from our other non-boost Disc WORDS are not compatible with this boost hub.

The BOOST Disk WORD hub has freewheel threading on the drive side for standard BMX style freewheels, and a 6 bolt ISO rotor mount.

The flanges are canted towards the rim, and the spoke holes are chamfered to reduce stress on the head and elbow of the spoke.

Made with pride in Chico, California.

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.

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.

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.
