Product Description

ROTOR T4724 threaded bottom brackets are the new addition to our 2021 lineup. This bottom bracket fits any frame with a standard T47 bb shell, which has emerged among boutique frame builders as well as some of the big names (most notably on a significant portion of Trek's 2021 line). T47 is on its way to becoming our new favorite bb standard in the office, mostly because it leaves plenty of room for internal cable routing. As always, the bottom bracket cups are precision-machined in our Spanish manufacturing facility.

T4724E uses external cups, measuring roughly 11.5mm outboard on each side.

T4724I uses internal cups in which the only outboard piece is the castellated flange, which measures roughly 1.7mm on each side.
