Hey
As a secondary bike (primary one being a Cervelo S3 2014 6800), I own a Trek Pilot 5.0 2007 with Dura Ace 7700 rear derailleur and everything else being Ultegra 6500. It's in pretty good shape, everything shifts and behave smoothly, nothing wrong to say about it.
On the other hand, with my racing team I now have a sponsorship with Cannondale. I could get a SuperSix Evo 105 5800 at 40% off.
I know the SS Evo is different animal, I don't mind the much more agressive frame. I'm instead wondering about the mechanical components themselves. Would I miss my old 7700/6500 groupset?
Thanks!
