165 mm is Good!

We generally recommend 165 mm length cranks for road fixed-gear use. This shorter length makes it easier to spin faster cadences, and also reduces the risk of striking a pedal while cornering (with a fixed gear, where you have to pedal through the corners, this can be an issue.)

130 mm BCD Cranks for fixed-gear/singlespeed applications

For road applications with fixed gears, you can buy a genuine track crankset, but we normally recommend modifying a "road" double instead.

"Road" cranks are typically considerably less expensive, and use the 130 mm bolt circle, for a much better choice of chainrings at reasonable prices.

Any of the "road" double cranks listed below can be converted to single. All you need is a set of "single" chainring stack bolts.

130 mm BCD "Road" Double Cranks for Fixed/Singlespeed use

You really don't need a fixed-gear specific crankset for your fixed-gear or singlespeed bike. You can use a typical "road double" crankset with the outer chainring removed. You will need a set of short "stack bolts" because the normal double stack bolts will be too long once you remove the outer chainring.

Typical "road" double cranksets put the chainline of the inner (smaller) ring at about 41 mm, which works pretty well with a typical track hub.

See my Chainline Article for details on this.

In addition to the models listed on our main "road double" page, we always keep an eye out for good closeout deals on suitable cranks in 165 mm or shorter lengths:

Special Purchase! Sun Tour Cyclone 7000 Cranksets $79.95 160 mm only

Don't need no steenking pins and ramps? These are gorgeous cranks, with 42/52 chainrings. These N.O.S. cranksets were probably made in the early 1990s

These use the traditional tapered-square bottom bracket.

These use 130 mm BCD chainrings, same as the other "road" cranks listed here.

690 grams including the metal threaded dustcaps.
