Single Stack Bolts CR001 $6.95 set of 5 buy button

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 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.

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 buy button

KMC Half Link 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 buy button

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.
