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.

We’d like to take a minute to sincerely thank ev We’d like to take a minute to sincerely thank everybody who’s been so patient while we machine and build bike parts and ship out orders as fast as we possibly can while keeping our work-family safe and healthy. Making everything in-house means it can be a real challenge when it comes to dividing up all of our production areas into Covid-safe zones, and working staggered shifts (even on the weekends) has made 2020 a real challenge for us. Yesterday we were able to put some more brakes and brake levers back in stock on the website and we just replaced one of our CNCs with a fancy new (faster) machine, so we’re feeling optimistic. (The recent news of two vaccines makes it seem like there might be a light at the end of this tunnel?) Anybody want to see some setup videos of our new machine or does that just make your eyes glaze over?
