Product Description

ROTOR T4730 bottom brackets are available for frames with a standard T47 bottom bracket shell. T47 bottom brackets are on its way to becoming our new favorite bottom bracket standard in the office, mostly because it leaves plenty of room for internal cable routing with a 30mm axle. As always, the bottom bracket cups are precision-machined in our Spanish manufacturing facility.

Rotor's T4730 External uses external cups, measuring roughly 11.5mm outboard on each side.

Rotor's T4730 Internal uses internal cups in which the only outboard piece is the castellated flange, which measures roughly 1.7mm on each side.

Rotor's T4730 Asymmetric utilizes one inboard and one outboard cup, primarily for threaded BBRight bottom brackets.
