Surly  2010 New hub (front, disk)

The first thing you should know, if you don’t already, is that we don’t offer hubs designed for gear clusters. Those kinds of hubs are cool, with their ½-step ratcheted multi-pawl systems and sealed mechanism freehub bodies and all that. In comparison, our hubs are simpler. While we produce frames that can take gears, our hearts still lie deep in the singlespeed jungle, because of the simplicity, effectiveness, ease of maintenance, and default pragmatism singlespeeds offer. Do what you love, that’s what we say.

All our hubs sport what we would call ‘medium’ flange height, and they spin on fully sealed adjustable cartridge bearings. We use adjustable bearings so you can take out the play that develops over time as they wear. All of our hubs use steel axles and hardened steel hardware, and the axle threading is a popular standard, so that it will still be easy to find replacements should the need arise.

So you might think “Geez, singlespeed hubs only? Man, that doesn’t leave a lot of options.” You’d be wrong. You’ve got your disc or no-disc option, 32-or 36-hole option, color option, solid vs. hollow axle option, and gear threading option (singlespeed freewheel or fixed-gear cog and lockring). Combine that with four over-locknut-dimensions (OLD) and you’ve got all kinds of options. You know, as long as you want a singlespeed hub.
