Question for the wrenches. My new FSA bb and crank arrived today to install into my new Ti frame. So I Ti prepped the threads, wrapped a few strips of teflon tape around the bb threads and began installation being very careful to not cross thread anything. I get the ND side cup installed no problem and then get the spindle drive side started and get it in hand tight. Then I get my bb socket (LIFA) and immediately hit a snag; the socket appears to not be deep enough to reach the teeth of the bb, hitting the spindle. The socket works fine on Shimano, is the Park socket deeper? My next thought (short of taking the frame to the LBS) is to tighten a vise on the drive side and hand spin the bb on until tight, protecting the drive side cup with wrapping to prevent scratching or damaging the bb. Any other ideas?

The tool you have is probably on older version, not designed for ISIS BB's. The Park (BBT-5??) will fit without worries.

Please do not clamp your new BB in the vise. Bad.

Remember, the driveside gets snugged against the frame first, then the non drive gets tightened.

The vise on an aluminum cup is a bad idea. You will either defrom it, mess up the threads or both. Spend the ten bucks for the tool or the LBS would probably do it for half that.

First, your installation is backwards unless you just partially screwed in the left side cup.

All you need is the deep FSA splined tool that costs $10 or less. Then install the right side and to the specified amount, with a torque wrench. NO torque wrench?
time to buy one. The final step is tightening the left side cup.

Put the RH cup in a vise? Hope you're kidding.
