T-47 Bottom Bracket

T47 is a new bottom bracket standard, currently popular with custom frame builders and starting to be adopted by larger frame manufacturers. Fitted with high quality seals and bearings, our T47 Bottom brackets share the same high-quality design and durability as the rest of our range.

Description

Available with replaceable stainless bearings for less friction and greater durability
Designed to suit cranks with 30mm axles

Both T47 bottom brackets use our existing 30mm BB tool HTT0015S. The tool was modified at the beginning of August 2019, only tools produced after this will work with T47 BB cups. Revised tools are still fully compatible with our 30mm threaded BB cups.
