Does anyone know the size of the BB on a stock 2005 prophet? It has a TruVatiV ISIS GigaPipe SL right now and I'm starting to get movement in it. I would like to get a tough BB to replace it that would still fit the stock TruVatiV Blaze crankset. Any suggestions?
Thanks.

It should be standard euro 68x113mm, welcome.

Doesn't the E-type front derailleur make it a 73mm?

TVV uses spacer to make 1 bb fit all. The spacer configuration depends on the bb shell width and recommended chainline. In this case you have a 68 shell and want a 50mm chainline while using an E-type front derailleur. Also keep in mind that Shimano has made changes to their E-type front derailleurs which adds another element of surprise to the event. Cannondale does have a setup guide based ont he cranks that they spec. You should find them helpful.
