Quick question. Does the current modern SuperCorsa still have Italian threaded BB? So the right drive side threading is reversed(left-hand thread, which tightens counterclockwise and loosen clockwise)? Just want to confirm. Thanks.

...I presume so. Don't know why they would have changed the standard, there in Italy. But if the frame is right there in front of you it's pretty easy to tell.

An Italian BB shell is wider than the standard 68mm everyone else used. So it would measure 70mm wide. And if you have a standard, RH cup from something else, you can try fitting it in there. It will be way too loose. Italian threading is the largest diameter of any of the standards. Look here.

I've seen one bicycle frame made in Italy that had a standard BB, but it was some off brand, lesser bike frame.

ok, I figured out. So if you look into the BB from either side on this modern SuperCorsa, counter-clock wise is loosen, clock wise is tighten. This is the case for both sides. I admit this threading thing is distance memory for me since I've been dealing with press fit type BBs in the last 10 years. I'll save 1000 words on those dreaded press fit systems....

It's a joy to thread cups into the frame with just bare hands and tighten the last bit with a torque wrench. Just simple, smooth and beautiful...

Good call on the polished stem. That looks great!

...the one thing to remember is that because of precession, thus the tendency to loosen on the drive side on an Italian BB, you need to either use Loctite or torque that cup very tightly, or it will back out. It's not as much of an issue with a sealed unit BB assembly. Put with cup and cone the drive side needs to be very, very tight in the frame.

The drive side cup label says 35nm. But it's pretty light after I torqued to 35 with my torque wrench. I feel I can tighten it a lot more, but I wonder if it's going to damage the cup

...looks like an aluminum alloy of some sort. I would go with blue Loctite, rather than tightening it a whole lot. Aluminum needs something to cut down on galvanic corrosion as well, or it's hard to remove it somewhere down the line. I don't actually recognize what sort of BB that is ? If it has sealed bearings, the races are in the sealed units, so that cuts down on precession forces on the cup.

This is the Campy 10spd Power Torque BB cup. Aluminum, with yellow loctite factory installed on them already.

...their torque specs are what you should use. My experiences is with considerably older stuff than that.
