On my new Trek 4300 Disc the wheel set that is coming with it has Shimano M495 disc hubs; WTB Speed Disc rims, are thses things durable at all? or am I going to pretzel these things doing 2-3 foot drops? If anyone has any insight to what these rims are like I'd love to hear it. The second part to this is, who makes the most durable beat the **** out of, and still stay tru rim? Wieght isn't a big concern, being strong is first and formost. Thanks guys.
