The BBT-9 Bottom Bracket Tool is designed to remove and install external bottom brackets which have an approximate outer diameter of 44mm. Laser cut for a precise fit, one end of the BBT-9 securely engages with the 16 notches found on the bottom bracket cups, while the other end engages with the 8 internal splines of the crank arm adjustment cap found on Shimano Hollowtech II systems*. This tool also fits rotor disc lockrings which use 16 external notches.Compatible with:
Unless you have the BBI Torque Wrench Adapter, this doesn't allow you to properly torque your bearings. I much prefer a socket tool for this reason.
Part of your money is going to the name on the tool. Part of your money is also going to a tool that will likely stay with your kit for your riding career. Pick this up when it is on sale, and know you'll have the best tool on the shelf for taking care of your bottom bracket. And also hope that you'll have the same style of bottom bracket as long as possible so you can get the maximum longevity out of your purchase. It is kinda like a Chris King part. You are partially painting yourself into a corner purchasing it. You'll have a great part/tool for your bike, but you'll want to ONLY pick that part/tool up from here on out in order to justify spending so much on it. Your other option is to exchange your tool/services for tasty beverages or dead presidents.
Nice quality tool, well worth the price. Much better than marring up your new part with some pliers.
Plenty of leverage available with the long arm this tool provides. Makes breaking loose the BB cups someone else overtorqued into my frame an easy task. And with the bit of weight this tool has, it could serve as an excellent attitude adjusting stick. Perfect for when other riders start whining too much about conditions, parts, or something else.
I considered going with something a bit less expensive. I thought of the old adage, "Buy an expensive tool, regret it once. Buy a cheap tool, regret it every time you use it." It's a great tool, and I'm glad I picked it up.
Excellent tool. Integrated crank socket on the end. No need to look for it in your tool box.
