Here's the setup: 2001 Santa Cruz Roadster with an ultegra BB and ultegra 39-53 crankset. The rear cassette is a 12-23.
Here's the problem: When I am in the 39 and about halfway down the cassette, the chain rubs on the big ring. I was told that Ultegra/105/Dura-ace only come in one length spindle for the bb, except for triple setups. Is there going to be any problems getting a triple bb for the setup I have now, or do any you folks have a better solution to this? Thanks guys.
