CeramicSpeed T47/73 Bottom Bracket - Shimano MTB Coated Races Black

On the trail, you need propulsion you can trust. The CeramicSpeed T47/73 bottom bracket delivers ultra-low friction and smoother power transfer, so every pedal stroke feels immediate and efficient. Built to outlast conventional bearings, it means fewer reps in the maintenance shed and more time enjoying the ride.

Who is this for?

Ideal for riders who demand reliable, race-grade performance on rugged mountain trails. If you value smooth pedaling, reduced drag, and longer service life from your bottom bracket, this is for you—especially Shimano MTB setups using Hollowtech II with a 47x73 shell.

Each item is professionally packed and shipped next day. Select in-store pick-up at checkout and visit us if you are local!
