Need to get some new rims. I've been riding Mavic XM819's. I thought cross country lite and all mountain strong. Turned out not to be so strong. I've put a few flat spots in them. I'm definitely not too brutal of a rider, like to think I've got some finesse. Anyway, who's got a favorite all mountain rim. I'm thinking either the Mavic EN521 or AtomLab Trial Pimp Lite. Dunno much about DT's and the Sun's are too heavy. Gimmie some ideas. Thanks.
