Out of sight and usually out of mind, the humble bottom bracket is the key to your bike’s smooth and efficient running. It’s the system of bearings and spindle that connects your pedal cranks to the bike frame and forms the connection between your power source (you) and your transport of delight (that’ll be your bike).
Smooth running
A well-maintained bottom bracket keeps your chainset running smoothly, making sure your bike performs at its best and giving you that secure, reassuring feeling that every ounce of effort is being translated into pedalling power.
Bottom bracket spares
There’s more than one type of bottom bracket, and we’ve got one-piece, three-piece, sealed cartridge and square tapered models from top brands including Campagnolo, Shimano and Chris King. We’ve also got torque cups and sealed bearings that you can use to upgrade your bottom bracket without replacing the full system.
