Reviews over the

Park Tool BBT-9

A good quality product as always from Parktool. Can be used to loosen/tighten BBs as well as for disc brakes with an external centre lock. The Shimano crank tool hanging from the tool is a handy extra, although I already had it separately among my tools.

Pros & Cons

bought to replace my brake discs with the external lock nuts, does the job delivered with the tip for shimano Hollowtech II cranksets

Pros & Cons

Had ordered these to fix with creaking bracket. Thanks to this spanner, I was able to open the bracket easily and therefore it doesn't creak with me.

Pros & Cons

Works fine, no damage to the old crank bearings and the new ones back on! Edges are a bit sharp from punching out the plate, but the handle fixes that.

Pros & Cons

As usual, the order was delivered quickly The key is basic and does its job properly
