Euro Bottom Brackets

Euro bottom brackets thread into the frame’s BB shell rather than pressing in. They use the same English (BSA) thread as most road and MTB bikes, so installation is secure, creak-free and simple, with no press needed. You’ll often find them on race frames and some street frames, and they come in 19mm, 22mm and 24mm spindle sizes to match your cranks.

Check your frame’s BB shell and your crank spindle size before ordering.
