  • RRP £120.00
  • Saving you £10

This 12 speed road bike chainset features a durable aluminium crankarm construction, which makes it ready to handle the demands associated with modern road cycling. Whether you're clocking up the miles on your favourite road routes or exploring new gravel paths on countryside backroads, this versatile model is well-equipped for wherever your ride takes you. 1x12 Speed Chainset with X-SYNC Chainring From the company that originated the 1x drivetrain, this chainset benefits from a SRAM X-SYNC chainring for the highest level of performance and durability on your adventures. Its tall, square teeth edges grip your chain earlier than traditional triangular-shaped teeth, so riders can enjoy powerful and consistent performance as they transfer all of their leg power to their pedals. Its secure, direct-mount X-SYNC chainring also features an aluminium build, which makes it tough and reliable when tackling mixed terrain conditions. Wide Chainline and DUB Bottom Bracket Technology Developed for straightforward installation and unmatched cross-compatibility across brands, this chainset is equipped with a DUB bottom bracket spindle interface. This adds durability and simplicity, while its longer crank spindle accommodates both road and mountain bike (MTB) width frame bottom bracket standards. Its forward-thinking and backwards compatible design makes the SRAM Rival 1x 12 Speed Chainset a great choice of upgrade for better sealing than ever before, consistent chain control over the long haul and a wider chainline to fit the biggest of gravel bike tyres. Technologies: SRAM DUB: Forward-thinking and backwards compatible SRAM DUB BB/Crank technology is the workhorse without restraint. Designed for the most discerning pros. And riders who set it and neglect it. DUB is compatible with all major bottom bracket standards. Offering better sealing than ever before, without having to make compromises to fit all frames. Yet it opens the door for a new crank spindle for the world’s all-time lightest crankset. It’s a new approach that embraces the old. And it’s about time. 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.
