Clean lines through the mud.

Cyclocross racing holds a storied history of single chainring lore and whispered advice on the best way to convert a double crankset to a single. For years, this process involved a quest for shorter bolts, much time cloistered in the garage trying to achieve an acceptable chain line, and many a crossed finger that it would work out on race day. SRAM took away all that hassle and brought one-by into the mainstream with the launch of its CX1 groupset last season. This year, SRAM expands its one-by offerings with the new Force 1 groupset, boasting exceptional cyclocross functionality that crosses over equally well to gravel adventures and road base miles. The Force 1 GXP Crankset sits at the center of the group with a perfect chain line and phenomenal, 'cross-friendly chain retention.

The crank arms are fashioned from light, stiff, unidirectional carbon fiber for swift, efficient power transfer and snappy responsiveness. At the center, a forged alloy spider provides a durable-yet-lightweight anchor while the SRAM X-SYNC chainring brings some extra chain retention features to the table to make this crankset really hum.

X-Sync chainrings feature a distinctly tall, squared-off tooth shape that catches the chain earlier in the pedal rotation than standard, triangular teeth, improving chain stability and retention. The teeth's narrow, sharp profiles and rounded chamfer edges also help with chain retention and minimizing chain deflection — qualities that strongly recommend the shape for one-by drivetrains. SRAM also includes recesses that help clear mud to move the chain swiftly through its rotation for smooth power transfer without any catches or muck suck — even in the oft-muddy conditions of 'cross.

The SRAM Force 1 GXP Crankset is available in either a 110mm or 130mm bolt circle diameter, each with several chainring size options that allow riders to maximize the ride experience based on their specific gearing needs.
