Older Park BBT-2 with new Ultegra BB?(6 posts)

Older Park BBT-2 with new Ultegra BB?Mandrake

I'm about to convert to triple, and I just got a new Ultegra BB w/ a 118 axle and OctaLink splined drive. Can I get away with using a four or five year old Park BBT-2 tool, or am I going to have to spring for a new one? I hear there may be clearance issues with the newer fatter axles. Thanks.
You should be fine...Mike Prince

BBT-1 is the original for the square taper cartridge BB's, BBT-2 is for the splined axle BB's. It doesn't matter whether it is a double or triple, the BBT-2 will work with all Shimano cartridge BB's.

Got around to trying it and my BBT-2 does NOT fit over the fatter end of a Shimano splined axle. Off to the LBS to buy a new tool, I guess.
Yup, you need the new toolKerry Irons

The older tools were beefier and don't have room internally for the splined axle. The cup splines are the same, but you can't get enough engagement from the tool to actually remove or tighten the cups.

Ultegra cranks should have self extracting crank bolts which do not require any tool beyond an allen wrench.

The cranks do have self-extracting bolts, but that's not the issue. I needed to install the bottom bracket. I wound up buying a pretty nice tool from Trek - BB cup tool on one end of a long lever and casette lockring tool on the other. Lockring tool has a tapered rod sticking out of it that slides into the axle for easy centering. Pretty nifty, and eliminates the need for a socket handle or crescent wrench.
