MegaEvo Bottom Bracket T47 Threaded

The FSA MegaEvo Bottom Bracket T47 Threaded brings smooth, efficient pedaling performance to modern threaded frames with oversized crank spindles. Designed for riders who demand stiffness, precision, and long-term durability, this bottom bracket lets you run a 30mm MegaEVO or BB392 crankset on a T47 threaded frame with 68mm or 73mm shell width. Whether chasing watts on the road or hammering through rough gravel, its tight tolerances and sealed bearing design keep every pedal stroke clean and consistent.

• Versatile compatibility – Fits T47 threaded frames (68/73mm) with MegaEVO and BB392 30mm cranksets.
• Stiff and efficient – 30mm spindle interface maximizes power transfer and pedaling response.
• Precision machining – Ensures a secure, creak-free fit and long bearing life.
• Easy installation – Works with standard FSA tools (BTI #FS-0290 or #FS-0291).

The FSA MegaEvo T47 Bottom Bracket is the ideal choice for riders upgrading to a 30mm spindle system without sacrificing the reliability of a threaded frame interface.
