Park Tool Bottom Bracket Tool - Hollowtech II - BBT-9 $21.49
Don’t break a sweat; use the BBT-9.
This is Park's shop-quality tool for installing your Shimano 10-speed Hollowtech II bottom bracket cups. It's long enough to give you adequate leverage for installing the cups with the force you need. The precisely shaped metal teeth of the BBT-9 won't damage the teeth on your BB cups provided you use it with care. The small end of the BBT-9 has what looks like a plastic wheel on it. This is actually, the splined plastic tool that you'll need for the spindle bolt to preload the bearings on your Hollowtech crankset. Otherwise, the Park Tool BBT-9 is compatible with Shimano Hollowtech II, FSA Mega Exo, SRAM GXP, and most other external bearing bottom bracket cups.

Good product/tool. Works as expected.
Gets the job done
- Familiarity: I've used it several times
not much more to say. sturdy and works. Done.
Unlike the Shimano version, this handy tool combines the BB cup tool AND the preload bolt tool. My friend with the Shimano version just lost her preload bolt tool and tried to use needle nose pliers, which marred the crap out of the soft plastic Shimano uses. Made me so glad I bought this one. Like most Park tools, it's well thought out, made well, durable, and a pleasure to use.
This is the right tool for the job.
