Origin8/Formula

We now carry Formula cartridge bearing hubs, under the Origin8 name, as our stock fixed-gear hubs.

These hubs are also featured on some of our stock wheels.

Origin8 Hubs Origin8 Flip-flop hubs

HU105 36 hole Front Silver $42.95 buy button

HU109 36 Hole Rear Silver $42.95 buy button

Double-sided fixed/fixed rear hub in 120 mm spacing, (adaptable up to 130 mm) with standard track 42 mm chainline to fit most track frames and many road bike conversions.

Designed with a look reminiscent of the classic Campagnolo Nuovo Record, with milled flanges with lightening holes.

These hubs have HOLLOW CORE lightweight heat-treated axles. Good quality track nuts, large serrated locknuts to keep them from slipping.

Sealed cartridge bearings. Does not include lock ring for fixed gear cogs (but if you leave the lockring off, you can install singlespeed freewheels on one or both sides.)

Axles are not readily changeable, so these really can't be converted to quick release.

New White Industries ENO Single Speed Hub

Splined Version! ENO eccentric single speed hub $159.95 buy button

Exclusively for use with White Ind. splined fixed gear cogs (sold separately).

This design eliminates cross threading and cog movement. The cog fits securely in place with White Ind's precision machined spline system.

Use any standard thread lockring to secure cog. Freewheel side will take any standard thread freewheel.

The ENO hub is designed for a 47.5 mm chainline, which matches the middle position of a typical MTNB triple crank.

A typical "road" double gives about a 46 mm chainline with the standard bottom bracket, which is a decent match. Ideally, you would want to adjust the chainline to be perfect, though.

The Sugino RD crank we feature gives 47.5 chainline when used with a common Shimano 110 bottom bracket, so if you need to buy a crankset anyway, this would be a great combination. The ENO hub uses an oversized aluminum axle with stainless steel ends that fit into the axle. The ENO comes equipped with two sealed cartridge bearings and is available in 32 and 36 hole versions.

The eccentric axle provides a total adjustment of range of 15 mm. Each tooth added or subtracted to your drive train requires that the axle move 1/8" (3 mm) backward or forward.

Most folks find that the best setup is to use a fixed gear two teeth smaller than the freewheel gear. The idea is to use the fixed gear for general riding, and to keep the lower freewheel gear in reserve for longer rides, steeper terrain, or when you're just plum tuckered out. The lower gear will make the climbs easier, and the freewheeling feature will let you rest on the downhills, but you'll be slower on the flats.

Note that the offset will effectively raise or lower the rear end of the bike a bit, and will move the rim downward or upward with respect to your rear brake, if you use one, so some adjustment may be required, and some frame/brake combinations may not work.

Single-speed Freewheels

Freewheel compatibility notes:

3/32" freewheels can be used either with narrow (3/32") or wide (1/8") chain with no problem.

Freewheels can fit on fixed-gear hubs with no problem, just leave off the lockring.

Nuts & Bolts

 

Track Nuts $7.95/pair buy button

Track Nuts
Track NutsStandard
Serrated Flange Nuts
Proper track nuts have integral washers. They permit easier adjustment of chain tension, and hold the wheel in place better.
10 x 1 mm Fits Shimano, Surly rear hubs and most freewheel hubs.
9.5 x 26 tpi Fits Sovos and Suzue rear hubs(Except for Suzue NJS)
9 x 1 mm Fits Shimano front hubs and most freewheel hubs.
These 9.5 x 26 tpi track nuts fit the Sovos and Suzue hubs we sell.

We also carry other sizes for other hubs.

Single Stack Bolts $6.95 set of 5 CR001 buy button

Single stack bolts
It looks really goofy to ride a fixed gear with a useless extra chainwheel on your crank. These track-style stack bolts are the right length to hold a single chainwheel to your crank. They fit all modern cranks.

3 mm Chainwheel Spacers $2.95 set of 5 CS001 buy button

For budget road-to-fixed conversions, a quick and dirty way to make the chainline work is by spacing the chainwheel inward from the crank spider.

This is especially useful if you're using a hub made for a multi-speed freewheel, because it reduces the amount of re-dishing required.
