SRAM SX Eagle PS 12sp MTB Chainset - BoostThis Boost-spaced mountain bike (MTB) chainset features an aluminium crank arm construction for fantastic durability on the toughest of rides. SRAM has also equipped this model with a single steel chainring, so you can benefit from its reliable and precise chain retention as you ride across the trails. Coming kitted out with Eagle technology, it offers lighter, simpler and more durable performance than standard 12 speed cranksets. Eagle technology also provides an expanded gear range of 500%, which is equal to that of 2x11 speed drivetrains, while maintaining a significant weight advantage. This makes it a great option for off-road riders who want to benefit from the same chain retention performance as seen on the higher-level Eagle drivetrain cranks but at a wallet-friendly price.
