Campag Ultratorque chainset removal

[SteveParry]

I need to install my new Nerius 34t 110 BCD inner chainring. Am I correct that I should not use a torque wrench to remove the bottom bracket? I read somewhere that torque wrenches are designed only for tightening not un-tightening. Seems the recommended torque for tightening is 45-50Nm. Glancing at stores it seems most 1/4" wrenches only go up to 25Nm. Should I be looking for a 3/8" wrench? The five crank bolts on mine are definitely not hex. They seem to be torx - is that correct? Asking because I don't want to round them out.

Not familiar with your chain set, but on the ones I have, no need to remove the BB. Just remove the outer ring and then the inner, while the BB and spider remains in place on the bike.

I think the crank bolts are torx T30.

Have in mind the Campag recommendation to replace the chain bolts whenever you install new chainrings.

It does give you more access if you do remove the crankset.

Does this video help?

Lastly, if it is a Super Record set up, the crank bolt has a left hand thread.

On a Campag Ultra Torque you don't need to take off the bottom bracket to change the chainring. You just have a single (very big) hex key in the middle that you undo and the two halves of the girth joint axle split in half. I couldn't use a torque wrench on that bolt even if I wanted because the hex head is so far embedded in the axle the only thing that worked for me is a long 10mm hex key.
The bearings are also pressed into the chainset so you never need to undo the cups, even if you need to change the bearings.
Chainrings are a T30 bolt.
