Customer Reviews (4.7 / 5 · 3 reviews)

Ryan ★★★★★

The 16-notch design fits my threaded bottom bracket perfectly, no slipping at all during installation. I appreciate the anodized finish that should resist corrosion in the shop.

Avery ★★★★★

The CNC-machined aluminum body feels rock solid in my hand, and the 16-notch fit locked onto my bottom bracket with zero play. It spun the cup out cleanly on the first try, no slipping or wobble at all.

Thomas ★★★★☆

The CNC machining is really clean, so the tool engages the bottom bracket cup without any wobble or slipping. It does the job perfectly on my threaded BB, though I wish it came with a slightly longer handle for extra leverage.
