The SRAM S300 1.1 GXP crankset is one of our go to upgrade cranks here at our shop in Milwaukee. Light, stiff and affordable, the S300 crankset is a great upgrade for any serious fixed gear rider. An added bonus is that includes the bottom bracket. This is a great alternative to the more expensive SRAM Omnium Crankset.
Crank arms are forged aluminum, use the same bottom bracket interface as high end models.
