SEIDO PRO Bottom Bracket - T47 - 85.5-86.5 | Internal - black

SEIDO PRO T47 BBs are machined to precision with the highest quality aluminum and bearings. They will fit 30 mm spindle cranks with the included washers, or can be fitted with SEIDO adapter kits to accept other crankset spindle standards. The BB sleeve has been designed to leave room for internal cable routing. Servicing or replacing bearings is an easy job thanks to easily accessible bearing races, even when fitted to the frame.

Outer seals provide extra protection for the already double-sealed bearings.

SEIDO PRO BBs use 2x 6808 bearings (30 x 40 x 7mm, IDxODxW).
