The FSA K-Force Track 1x Crankset is a single-ring track crankset from FSA, built for velodrome and fixed-gear setups where there is no front derailleur and no need for a second ring. It comes with a 49-tooth chainring, a common gearing for track riding when paired with the right cog.

The K-Force name sits at the performance end of FSA's range, and the track version applies that to a crankset made for a single, fixed drivetrain. Arms are available in 165mm, 170mm and 172.5mm. The shorter 165mm length suits riders who want more clearance when pedaling through banked turns, while 170mm and 172.5mm are the usual choices for riders who prefer a longer lever.

If you are building or upgrading a track bike, check that the crankset's spindle and bottom bracket standard match your frame before ordering. The 1x layout keeps the drivetrain simple, with one ring, one chain line and nothing else to adjust.
