It wasn't disconnected, that was just a sensation. Also, though the bike is stiff, like so many stiff frames it was not particularly comfortable and was much less so than it's Trek 2500 predecessor. Trek has an excellent lifetime warranty program and so when my frame had an unusual discoloratin appear at a joint, Trek warranted the frame for me. This frame would be good for a racer, but for me, I am more a fan of steel and titanium. The bike is stock except for Speedplay pedals.
Carbon fiber takes some getting used to.
The Rolf Vector Pros are great for events but if you break a spoke you are done. It transfers the power to the road but doesn't beat you to death like the 2.8 C-dale. I'd work a little extra O.T. to afford it. I highly recommend 'em. This bike is simply the best.
