Reviews

Better than sram

"To replace a sram gearbox that cracked after 100 km. No problem, holds up well. Comes with tool for mounting".

— Vat55 (4/5)

Wrong diameter

"The right-side bearing is too narrow, I had to tap it with a mallet to get it to fit. The (very low-end) tool that came with it for installation bent on the first tightening (to torque of course. . . ) Too bad for the price, I'll stick with Sram."

— Djez (1/5)

Very nice

"nice finish, key, fluid, spacers, what else."

— Laulau (5/5)

Bearing housing

"Mounted with eagle 52 t dub supplied with wrench".

— Jylwolfen (5/5)

Solid

"As a replacement for the SRAM, which had outlived its usefulness, the Black Bearing seems extra solid. And the crankset turns like crazy. Possibility of cleaning the bearing and regreasing it."

— Jf003 (5/5)

At last!

"After the BB from the original brand, it's night and day. What fluidity! What a lack of resistance! I'm bluffed, I didn't think the change would have such a radical result."

— Poulpinaz (5/5)
