I LOVE Campy cranks but they are limited and pose a problem for a lot of us.The tripilizer is a solution but unless you have something like a Phil BB where you can set the crank out for the chain line, then you need a different spindle. I have a couple with the rare TA 41 small ring but that doesn't help that much, especially when the NR/SR rear derailleur only handles a 28 tooth low on the FW. I am going with a Sugino 110BCD crank for my touring bike and putting a Cyclone GT RD with a 32 tooth low FW . I have the parts so why not?

This was my "donor bike " I bought just for the wheels for my Raleigh Pro and now a source for getting low gearing on my touring bike
