just giving you a hard time about the superbe stuff, but where do you live where you can't hang with a 42-28? Maybe when you build up your strength with all your racing you can push bigger gears and then go back to the superbe components. I'm an italian bike nut and think that the suntour components were the best, simplest components made. I think your best bet would be to buy a campy 10speed front d and play with that, if the chainring bolts don't work. There's a reason that bikes don't typically come set-up with mismatched parts.
