I got a set of mavic Cross Land wheels in order to put the disc brakes on my new EPIC and I think these are really good wheels at what may be the best price for the performance around.
The wheelset was 229.00 at my LBS for disc ready, tubeless (if you want to run them, I don't) and strong wheelset. To run tubes you remove the plastic seal strip and replace with rim tape. I have been riding them now for about three weeks and love em. I'd love a set of Crossmax SL's but for less than a third the price these are fine by me. The weight difference is about 400 grams total.
I'd equate these wheels to be basically on par with Cosmos for the road, good construction for a great price.
