When we first introduced our Wacky One-Speed Rear Device (W.O.R.D.), it was the first purpose-built single speed mountain bike hub. That original hub not only set design standards that continue to this day, like a 52mm single speed chainline, it also proved that small American manufacturers could stand out in a market increasingly crowded by bigger overseas brands.
When designing this modern version of the WORD, we spread the flanges out as far as possible while leaving room for freewheel threading. This allows the WORD to be built up as a strong dishless wheel. Over the years we’ve also improved upon the original axle and bearing adjustment mechanism to produce a single speed hub that we’re proud to call one of our “heritage” components.
The WORD comes with special machined axle bolts which we affectionately call “Fancy Bolts”. The washers are made of brass and have deeply knurled contact faces. This ensures they’ll grip onto dropout faces without marring the frame, yet will still be able to be loosened easily trail side.
The WORD can be easily adjusted with our cinch bolt style adjuster ring.
Spoke hole counts are available in 28, 32, and 36, and the spoke holes are chamfered and the flanges are canted towards the rim to reduce stress on the head and elbow of the spoke.
