Just tonight I removed my Bontrager Race wheelset because of cracks around several spokes on the drive side. They had 1,200 miles on them and are now junk. I weigh 200 lbs. I've heard of light weight folks doing much better with these wheels but I sure wouldn't buy another set. I replaced my wheels with a used set of Spinergy Sealth PBO. I hope they work out better for me.
