SRAM's only single speed road crankset (with the discontinuation of the Omnium) is a lightweight option with a GXP bottom bracket. SRAM positions this as a courier crankset though it is set up as more of a road conversion crankset (like the Sugino RD2) with a 130BCD, 3/32" drivetrain and wide Q Factor. The wider Q-factor makes it work well on a variety of frames and conversions.
