Hubs typically seem to fall into two general categories: light and very expensive or heavy and cheap. With this typical bike industry paradigm, we saw an opportunity. You see, for years we've been using high-end geared hubs from the manufacturer of our track offerings on our personal bikes. They are very lightweight (peep the specs) and just plain work. We decided to finally make those hubs available to you and corner the market in our own category: lightweight, affordable, and incredibly practical. We've ridden them on all kinds of bikes from the Electric Queen to the Mr. Pink and we're in love. They are reliable, dang light and very reasonably priced. We offer the Go-Devil in a minimal amount of configurations and ship them with all the necessary endcaps and a quick release skewer, future proofing them in case you want to use them on various bikes over the years. Quick Release lever and 12mm thru-axle endcaps are included. On all models we spec high-quality made in Japan stainless-steel sealed bearings. The splined freehubs have 28 points of engagement, the XD driver has 56. Oh, and we've got polished options as well. Kind of a big deal because polished hubs have become a rarity. - Weight: 277g - Includes 12mm thru-axle end caps and quick release skewer - Drive Side Center To Flange 18.5mm - Non-Drive Center to Flange 34mm - Non-Drive Flange Diameter 58mm - Drive Side Flange Diameter 49mm

New Sheriff hubs are the ultimate in track racing hubs. They minimize weight with larger cutouts in the flanges, lightened axles, shorter bolts, and slimmer end caps than previous versions. The result is a hubset that weighs a mere 432g, 198g for the front, and 234g for the rear. This makes it one of the lightest track hubsets in the world, a figure even more impressive when you consider that All-City didn't eliminate the usefulness of a fixed / fixed or fixed / free option as most racing hubs do. They feature the finest Japanese manufactured 6902 bearings which roll incredibly fast and smooth while retaining excellent seals for all weather, all-day everyday durability.

There is a wild spirit here in the southern Appalachian mountains, from the dense rhodo and laurel forest, to the rushing rivers, and fog-covered valleys. This is the same spirit that inspired the bootleggers and moonshine runners to soup up old cars and illegally run shine from the law through the dirt roads that litter this landscape. They knew these roads like the back of their hands and knew exactly how much speed they could hold in every turn, in every condition. This spirit lives in mountain bikers who call this place home. Factor 601 was designed to meet the demands of these riders. From the oversized alloy shell, EZO bearings, easy maintenance, and low friction coasting, these hubs are the perfect companion to a rip through trails you may or may not have permission to be on!
