I've just swapped out a Campag Ultra torque crankset after a few creaking problems that I just can't solve. That involved buying at least two new tools and took quite a while. I drew the line at buying a torque wrench that would go up to 45 Nm. The crank has had a long and useful life so probably needs new bearings, cups and retailing clip anyway. In the meantime I thought I would put an old style BB in and slot on some old square taper cranks. Simple and it works like a dream. I really can't see that it performs any worse than the outboard BB. If I was to resurrect the Ultra torque its going to be £20 for new cups, £20 for new bearings, wavy washer and a retaining clip perhaps another fiver. I'd need a campag bearing puller, £50 , and a long arm tool wrench is £100 plus. That might not even solve the creak problem. What if the Hirthlink inside has been damaged? For a lot less than that I could buy the dog's dangly bits of a square taper BB and even some new chainrings if necessary. Is there a massive advantage to outboard BB that I am missing? Apologies if this debate has all be done before.
