Description

ROTOR T4730 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 with a 30mm axle. As always, the bottom bracket cups are precision-machined in our Spanish manufacturing facility.
