SRAM Force1 12 Speed Chainset Chainsets
  • £199.99
  • RRP £225.00
  • Saving you £11

This race-ready 12 speed chainset features a carbon crankarm build, which means that riders will enjoy increased stiffness when climbing and an overall lower weight when accelerating on the flat. Its impressive strength to weight ratio is further enhanced thanks to its single X-SYNC aluminium chainring that provides exceptional durability and longevity as you tackle whatever the course throws at you. Coming equipped with X-SYNC technology, this model's chainring uses its wide/narrow tooth profile to deliver maximum chain control for an extra confidence boost on race day. One final highlight is its kitted out with a DUB compatible spindle interface for a simpler, stiffer, and more secure connection between your chainring, cranks and bottom bracket.  SRAM originated the 1x drivetrain, and the SRAM Force 1 crankset evolves the innovation. It's lighter, stronger and simpler—non-aero chainrings can now be installed with a single tool. For cross, time trial (TT), triathalon and crits, this is the king of 1x. - Single-ring drivetrain simplifies functionality and reduces weight - 48t variant has direct mount aero chainrings for better aerodynamics - Non-aero chainrings can be installed with a single tool, making gearing changes a breeze - SRAM X-SYNC™ wide-tooth, narrow-tooth chainring technology provides maximum chain control - DUB™ bottom bracket adds durability and simplicity - Can be upgraded to a power meter Technologies: X-SYNC: SRAM X-SYNC 1x chainrings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle-shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC rings are an integral part of the SRAM 1x drivetrain. Accept no imitation. DUB: The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler—better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete system that equals better drivetrain performance. Bottom bracket sold separately.
