A great product!
"I bought this housing for a BB30 format frame. It allows mounting with a 30 axle, the bearings being located outside the frame. Well done to this small company from Brittany: it's very efficient and innovative for a BB30, as it allows a large size for the bearings for a 30 axle, a guarantee of reliability. What's more, the casing is mounted in 2 plastic sheaths that fit directly into the bore on either side of the frame. As a result, the aluminum housing is not in direct contact with the frame's steel bore, which prevents cracking. Note: Blackbearing offers several bearing options: B5, B5 Inox, SKF and Ceramic."
