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

Surly's Ultra New Disc Front Hub is a gorgeous hunk of aluminum that boasts reliable sealed bearings and a 6-bolt disc attachment. The forged chromoly axle is flex-free for steering precision, long-lasting durability and simple quick-release compatibility.

Surly's Ultra New Disc Rear Hub is just the thing for singlespeed fanatics and one-gear mountain riders. This gorgeous hunk of aluminum boasts reliable sealed bearings and a 6-bolt disc attachment on one side and threads for a singlespeed freewheel (or fixed cog) on the other. A hollow axle lets you choose how to secure it to your dropouts. You have choice between the included fixing bolts or a quick release skewer (sold separately). And, that aforementioned chromoly axle is flex-free to take all the abuse you can dish out, and then some!

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.

WHY WE MAKE THIS Originally, we made this hub to be the cornerstone of our hub product line. It was one of those product releases where we put all our hub and bearing experience into, and ended up with a hub that struck that perfect balance between weight, performance, durability and looks. Since the advent of disc brakes (and the R45D), we keep making it, because it’s still that cornerstone hub, and so many of our riders still love to rock their rim brakes on road and off. WHY YOU WANT IT The R45 front hub is lighter and more aerodynamic than most built-to-last hubs on the market. Our R45 rear hub combines a redesigned RingDrive™ system with 45 teeth for lower drag and near-instant engagement with a lightweight hub body and our legendary made-in-house bearings. Our bearings, both steel and ceramic, have heat-treated, surgical grade steel races that are machined simultaneously to ensure perfect matching. The quality and speed of our bearings is what you will feel (and hear) on every ride. As Chris King bearing tracks burnish they get actually get faster. A little bit of regular love (i.e. service) will keep this hub rolling for years upon years of demanding use. All Chris King rear hubs come with that signature, angry-bee sound. - Steel Bearings - Engineered, manufactured, and assembled in Portland, Oregon USA - King Lifetime Warranty - Legendary made-in-house bearings - Easily serviceable with a 2.5mm hex and pick or pen knife - Completely re-buildable with our R45 Hub Service Tool - Available with Shiamano/Sram HG or Sram XDR driveshell - Available in 28h and 32h - Ceramic bearing upgrade available HUB SPECIFICATIONS - Axle Width: 130mm - Flange Diameter DS & NDS: 51mm - Center to Flange DS: 17mm - Center to Flange NDS: 34.3mm

WHY WE MAKE THIS It's our job to make the best riding hubs in the industry, and 142mm x 12mm rear hubs are THE standard for road disc and gravel bikes, so we poured our hearts and souls, not to mention an awful lot of engineering, into this hub. We think it's the best all-around disc hub on the market. WHY YOU WANT IT R45 Centerlock™ hubs combine a lightweight hub body, our legendary made-in-house bearings, and Centerlock compatibility. The result rolls better, lasts longer, sounds cooler, and looks way more handsome than anything else out there. On top of all that, the 45 points of simultaneous engagement in this hub improve power transfer and traction thanks to our patented RingDrive™ system.
