Currently I'm looking at Mavic XC717 with Hope Pro II hubs. These are nice & light, should be plenty strong enough for the riding I do & are quite well priced for a complete rebuild (with black spokes). They also came out top in a round up of wheel builds in What Mountain Bike.
All good. but I'm wondering if it might be worth me going up to the, slightly heavier & beefier, XM719 rims with Hope Pro II hubs for the rebuild? I want to be running 2.1" tyres, which I think is about the max the XC717 can accomodate but I've read reviews where people have been running these no probs on these rims.
