T47 External Bottom Bracket
Out of Stock
Don't worry though, we have a lot more Gravel & Cyclocross Bottom Brackets in stock than that.
Shop Similar ProductsMulti-layer sealed, USA-machined T47 external BB fits 68–73mm shells with one adjustable sleeve
The Wolf Tooth T47 External Bottom Bracket covers road, gravel, and cyclocross frames in 68mm and 73mm shell widths without requiring separate cup sets for each. One adjustable-width sleeve handles the range, and the same AISI 52100 chrome steel bearings with Acosur ZNA coating and multi-layer sealing Wolf Tooth uses across their BSA lineup are machined and assembled at their Minnesota shop.
What Our Gearhead® Experts Are Saying:
"I spec this on builds where the frame is T47 and I want a bottom bracket that won't need to be fought out at the next service. The multi-layer sealing keeps grit out, and the Acosur ZNA-coated bearings stay smooth well past where a cheaper unit starts to crunch."
