SquareTaper to Campagnolo Ultra Torque BB

bianchibob

My wife has an aluminium framed lady specific Bianchi, currently running an old square taper bottom bracket and Campagnplo Veloce front rear derailleur etc.

I would like to change the bottob bracket to a Campagnolo Ultra Torque system with a Veloce 50/34 crankset to complete the set up.

My questions are as follows, what thread would the bottom bracket be, Italian or English and what width 68 / 70mm ?

Any helps would be appreciated.

68mm english is the most common - should say on the bb in there if you remove it or take to your LBS

Depends on the frame model/year - most Bianchis these days are from the Far East with BSA threaded BBs whereas older, Italian-made frames are ITA.
When you unscrew the BB, if the threads are clockwise / counterclockwise then it's BS thread, whereas Italian is counter-clockwise both sides. Only ITA uses a 70mm shell.
FWIW Veloce chainsets now use Powertorque BBs - only Chorus and Record use the superior Ultratorque design.

Think twice before you fit a Campag Powertorque chain set. It needs a special puller to service it and it is not easy to improvise.

You can still get veloce ut nos though, so the OP should be fine in that respect. I got one a year or two ago for around £100.

Same here, got a veloce standard ut chainset nos for 100 quid from sprockets UK on eBay. Read too many stories about power torque being awkward. The ut Bb and chainset was simple to fit and looks simple to strip if required.

They are not "stories". Powertorque are easy to assemble,agreed. Tell me removing the left hand crank is simple when you have done it.

I am talking about power torque. The lefthand crank is fastened to the end of the bb spindle. Removing the crank without the campag kit and without damage was very difficult.

You are talking about changing the bearings? Yes it is a PITA. Basically special bearing puller.

Do you guys not understand English? I repeat, I am talking about removing the lefthand crank . Yes,you have to do that to change the bearings. Replacing the bearings after you have got the crank off still needs a bearing puller.
