DIY MTB BBRight Thread-Together Pressfit Bottom Bracket

DIY MTB BBRight Thread-Together Pressfit Bottom Bracket

A thread-together BBRight bottom bracket designed for compatible 79 mm x 46 mm press-fit frames. The interlocking cups join through the frame shell to improve bearing alignment and help reduce the creaking and movement often associated with conventional press-fit systems.

Compatibility

• For the BBRight press-fit frame standard: 79 mm shell width and 46 mm internal diameter
• Common BBRight frame examples include the Cervélo S5, S-Series, R5/R-Series, P5, P-Series, Caledonia/Caledonia-5 and Áspero/Áspero-5, subject to the crankset and spindle interface
• Suitable crank compatibility depends on the exact bearing and spindle specification of the supplied unit—please confirm this before ordering

Why choose a thread-together bottom bracket?

• Interlocking cups support accurate alignment through the frame shell
• More secure installation than separate press-fit cups
• Designed for a quieter, more durable bottom-bracket interface when correctly installed

Important: BBRight frames use a specific asymmetric shell standard. Confirm your frame’s 46 x 79 mm BBRight shell and crank spindle requirements before purchase. Professional installation with the correct bottom-bracket tool and torque is recommended.
