The Black Bearing aluminium spacer kits are precision components essential for perfectly adjusting your crankset within its bottom bracket. Whether it is to compensate for lateral play, refine the chainline, or adapt your setup to different frame standards, these spacers provide a reliable and durable solution. Made from high-quality aluminium, they resist compression and mechanical stress associated with intensive pedalling.
Each kit consists of 3 spacers with specific dimensions, designed to precisely fit the diameter of your crank axle (24 mm, 30 mm or DUB). It is an essential maintenance accessory to ensure smooth and quiet operation of your drivetrain.

- Robust design: Aluminium construction for excellent durability and low weight.
- Versatility: Three standards available to cover most setups on the market (Shimano, SRAM, Rotor, etc.).
