Complete drivetrain kit for steep climbs and mountain passes

Prepare your road bike for high mountains and steep gradients with this complete 9-speed climbing kit from Shimano. Tailored for riders who need lower gearing and a wider gear range, this set helps you maintain a smooth, efficient pedaling cadence even on the steepest ascents.

It is the perfect upgrade for tackling events like La Marmotte, riding in Mallorca or the Harz mountains, or simply giving yourself a lower rescue gear for local hills. Fully compatible across all Shimano 9-speed road and hybrid drivetrains.
