A follow up and some more campy questions

Rather than muddy up a prior thread, I am back with some info, and a couple more questions. I did not have a missing b screw, it is a 2mm hex, set into the rd. There is a barrel adjuster on the derailleur, see pics. The person who put on the grip shifters also set adjusters on the adaptors screwed onto the shifter posts. Now for the new questions.

1. Delta brakes - they appear to require a 3.5mm hex to release the cable. I don't have such an animal. Is this a campy one-off thing, or are there hex keys in that size?

2. Crank removal - they seem to require a large torx, but they stuck after a half turn or so. Is there a special way to remove the crank arms?

3. When, if ever did the italians switch over to english botttom bracket standards?

9/64 is the same as 3.5

Cranks should be hex, not torx. 7MM, if I remember.

Most 9not all) Italian bikes use IT BB. Campy has made English forever.

RD: Thats an old Chrous with A/B settings. Make sure both the upper and lower are set to the postion. I dont recall that allen screw being 2mm.. I thought it was 4mm
Deltas: 3.5mm odd ball for Campy. Harbor Freight allen key sets have the 3.5mm
Crank bolts: 7mm for Campy. Drip some chain lube under the bolt head. The last pair I removed needed a lot of effort to remove. I mean a lot!!

You might get a single 3.5 at Sears or a real good hardware store.

If your C-Rec cranks have the self extractors on them, that is how the feel. Initally the bolt will be tight until it breaks free from the face of the crank. Then it will move freely for a few turns until it comes into contact with the 'cap' portion of the self extractor then it will start to feel tight again. The top portion of the flange on the bolt is pushing against that cap. It should feel just like your using a Park crank tool.

I agree laying the bike flat and trying to drip some oil in under the cap is a great idea.

Bianchi pretty much went all English in the very early '90s. I think MAX tubed Protos were the last Italian BB bikes made.

This is how it is set up. The flange pushes the crank onto the spindle then also pushes against the cap to pull it off the spindle. This is for the bigger ISIS or whatever BB but the idea is the same.

Once again, a 9/64" allen wrench is exactly the same as a 3.5mm
