For sale: A pair of 26" MTB wheels - black Mavic X717 rims on XT M760 hubs. I used these on my commuter bike, so they are in great cosmetic condition with very little rim wear.
I'll weigh them in the morning and get back to you. I do know that X717 are one of Mavic's lighter MTB wheels, because I also use them on my best off-road bike.
