Here's one for you. My cousin went to go for a ride the other day, pulled the bike down and part of the front hub fell on the floor. Wheels are Bontrager Race X-Lites. Trek is doing a warranty replacement of the front wheel only. So he's getting the new Ti wheel, however they won't replace them as a pair. They want $350 for a new rear so he'd have a matching pair. I'm thinking he should sell the wheels separately on Ebay or something and go with a set of Open Pros with DA or Ultegra hubs. He might come out with some cash in hand from that. He's also thought about getting the rear and selling them as a pair. Not sure how he'd do on that. The set retails for $800, but the Trek Store has them on sale for $550. Any opinions on this?
