Subject: [CR]Front Derailleur Adjustment

Hello All,

I am putting the final touches on my winter build and I am having a problem with the front derailleur. There is rub on the outside cage plate when the chain is on the big ring.

The derailleur is a Cyclo Rosa, identical to the one seen here: http://members.aol.com/satorumas/brands/cyclorosarigide.html

The bike it is going on is a 1955-1960 Cinelli Model B. The chainrings are 50/47 on a cottered, 3-arm crank marked "Lightweight" (there is no other brand). The chain is a 3/32" Regina Extra.

My derailleur is not the original one, but I was told by the previous owner that derailleur (the Cyclo Rosa) is original to the bike.

Is there any way get the high-gear limit stop to extend a bit further, 1-2mm on this derailleur? The two adjustment bolts on the back seem to control the friction of the lever. And of course, I would prefer not to bend the cage.

These very old derailleurs are new to me and I don't want to chance damaging anything. Also, the LBS is not any help, they didn't even know derailleurs like this existed. Any information will be appreciated. Thank you.

Best regards,

David Beck Crystal Lake, IL USA
