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 mtb to road 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, 12mm, and 15mm endcaps are included. On all models we spec high-quality made in Japan stainless-steel sealed bearings. Oh, and we've got polished options as well. Kind of a big deal because polished hubs have become a rarity in our modern world. - Weight: Disc Brake: 164g - Includes 12mm, 15mm endcaps and quick release skewer - Non-Drive Side Center To Flange Disc Brake: 21mm - Drive Side Center To Flange Disc Brake: 36mm - Non-Drive Flange Diameter Disc Brake: 58mm - Drive Side Flange Diameter Disc Brake: 45mm

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. Front hub specs: - Weight: 198g - Torque Spec: 33nm (25ft lbs.) - Non-Drive Side Center to Flange: 34mm - Drive Side Center to Flange: 34mm - Non-Drive Side Flange Diameter: 62mm - Drive Side Flange Diameter: 62mm Rear hub specs: - Weight: 234g - Torque Spec: 33nm (25ft.lbs.) - Non-Drive Side Center to Flange: 29mm - Drive Side Center to Flange: 29mm - Non-Drive Side Flange Diameter: 62mm - Drive Side Flange Diameter: 62mm
