Nuts & Bolts

 

Track Nuts $7.95/pair

Track Nuts		Standard 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	$7.95	Fits Shimano, Surly, Formula/Harris/Origin8 fixed rear hubs and most freewheel hubs.
9.5 x 26 tpi	$7.95	Fits Sovos and Suzue rear hubs.
9 x 1 mm	$7.95	Fits Shimano front hubs and most freewheel hubs.

These 9.5 x 26 tpi track nuts fit the Sovos and Suzue hubs we sell.

Lock Rings

English/ISO Standard 1.29" x 24 tpi	Dura-Ace	FC001 $16.95	Standard size, fits Dura-Ace, Surly, Suzue, Formula/Harris, most other track hubs.
	New! All-City	FC003 $13.95	Standard size, fits Dura-Ace, Surly, Suzue, Formula/Harris, most other track hubs. Made of high-polished Chromoly stainless steel.
Right-threaded Bottom-bracket Lockring 1.37" x 24 tpi	FSA	BB019 $4.95	Not a track lockring, this is a right-threaded 1.37" x 24 tpi lockring intended for old style bottom brackets. If you are using a single-threaded freewheel-type hub, this is better than nothing, though not so secure as a real track hub with a left-threaded lockring.

Single Stack Bolts CR001 $6.95 set of 5 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 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. These also take up the space formerly occupied by the second chainring, so if you use these, you don't need to buy short chainring bolts...use the bolt set that came with your double crank or buy a double chainring bolt set here.

Chains and Links

Fixed gear and singlespeed bikes can use either ¹/₈" or ³/₃₂" chain.

Narrow (³/₃₂") Chains

This size is used on bikes with derailers, but is also excellent for fixed-gear bikes. This chain is lighter than the ¹/₈" size. We recommend this for most road fixed-gear/singlespeed applications.

³/₃₂" chains are listed on our Chain Page. We particularly recommend the SRAM PC870.

3/32" Half Links $3.95

If you are having trouble fitting the desired gears onto a bike with vertical dropouts, this link will let you add or subtract 1/2 a link (1/2 inch) from your chain, allowing you to move the axle 1/4" forward or backward. We never used to be able to get half-links for the narrow chain, this is a new item!

Wide (¹/₈") Chains

This size is traditionally used on track bikes and other bikes that don't have derailers. ¹/₈" chains are listed on our Wide Chain Page.

1/8" Half Links $4.95

If you are having trouble fitting the desired gears onto a bike with vertical dropouts, this link will let you add or subtract 1/2 a link (1/2 inch) from your chain, allowing you to move the axle 1/4" forward or backward. Different brands of chain have different diameter rivets; these links do not fit all 1/8" chains, but they do fit the models we sell.
