The chrome (?) plating is flaking off of the Bontrager triple crank that came with my '05 Lemond Sarthe I bought this spring. My LBS, where I bought the bike, says it's an equipment warranty issue and that Lemond will offer me a credit instead of replacing the crank. Cool, I'd rather have a Campy Veloce triple to match the rest of the gruppo on the bike. Will I also need a new bottom bracket? Do I need to make sure I get '05 parts only, or are all Veloce part compatible? What's reasonable for me to expect regarding the swap - no labor charge, minimal labor charge, or this is a real big PIA and I'm going to pay through the nose?
