No no no no NO! The hollowtech 2 bb uses a HT2 tool.
Do not use a screwdriver and hammer or any other tool!!! Shocked

To do it yourself you need one of these:

HT2 BB tool

The Truvativ GXP external bearing bb uses the same tool too.

Also if it feels like there is play the bearings have almost certainly gone! There maybe 2 pinch bolts on the non drive side, check if these are tight. If still play; buy the tool and a new bb.

Try here for a replacement: Superstar

There are no half decent BBs at the moment.
The only likely long lasting one is the new Chris King outboard bearings but that's not out yet and will cost a small fortune.
You'll get loads more miles out of a wobbling HT2 BB bearing though.

A friend who destroys things regularaly get's 1000miles out of BBs once they start wobbling.

OOpps!!! Embarassed Embarassed

Sorry Grant, didn't see that you'd said you had a Hollowtech, SeanO is right, though I thought your road bike was relatively new, that's why I thought it might be something simple like the loose lock ring.

I'm surprised at a BB "failing" so early in its life Confused Confused

How many miles do you think it has done and how old is the bike Question
