We build bearings, so we build bottom brackets. The humble threaded bottom bracket is often the first part installed on a new frame, and the last one the rider thinks about during the life of the bike, but the bottom bracket has a direct effect on pedaling efficiency (read: speed). This is where you put your power into the bike. Having the absolute best interface between your effort and your bike’s forward momentum makes your ride better. The Threadfit™ 30 is how we make bikes that take 30mm cranks the best they can be.
Why You Want It
ThreadFit™ 30 fits 30mm and DUB spindle cranks in BSA bottom bracket shells.
Our ThreadFit™ 30 bottom bracket is silky smooth and long-lasting thanks to our legendary, angular-contact bearings, both steel and ceramic, the best in the industry. They actually get faster over time as their contact surfaces wear, because we build them to ultra-tight aerospace tolerances, using machined, Delrin-spindle sleeves to create a perfect, and precise fit between cranks and frame. That’s where the low drag and butter smooth feel come from.
You want this bottom bracket because it offers super low drag. You want this bottom bracket, because it can be opened, cleaned and repacked for years of faithful service. You want this bottom bracket, because you don’t want to think an awful lot about your bottom bracket.
Our Threadfit™ 30 bottom brackets come in an array of beautifully anodized colors and each one includes a Fit Kit that allows it to be used with a wide selection of road and mountain bike cranks.
For DUB cranks we have two fit kits to choose from, Fit Kit #1 DUB A and Fit Kit #2 DUB B.
Fit Kit #1
DUB A is going to cover all DUB mountain fitments, as well as DUB road fitments with ThreadFit™ T47 bottom brackets.
