I might change the wheelset on my BMC. My R1's (black) covered approx 100 miles. I would be prepared to sell them for £450 for the pair with a Shimano freehub. Mint as only 2 weeks old. I have eyed a pair of wheels I like and feel they'd be better for me. I can post pics, info or whatever you want to know about. Let me know if your interested.
