Im planning on using these wheels for a light single speed trail bike, and some XC from what ive read on the internet sounds about what they were made for am i right? They're laced to Specialized S works hubs, 3-4 cross in the rear with radial in front 28 hole im a light guy 145lbs. Do think ill have good luck with em?

They're Mavic and the rim ends are welded (SUP) so they're going to be tough. A radial pattern isn't the strongest for a front rim though....

Should i get it relaced? I like the way radial looks i know its weaker i thought maybe i could get away with it because of my weight. Thanks

I don't think you'll have any problems with the front wheel. There aren't any torsional loads placed on the hub and spokes with rim brakes.

IMHO the 517 is one of the best rims Mavic made. I found mine one at a time to add to my Rockhopper. I'm seriously thinking of relacing them to disc hubs to keep those rims when I go to disc on that bike. At 145lbs I don't think you're going to have any problems.

Thanks guys i really didnt want to change them any i really like the way they look

You will be fine , although the sidwalls on those rims are about toast. I would of bought them myself except for that little issue.

You a fellow boise resident Fred? I bought them on friday during BBPs 50% sale paid 30 bucks for em so i figured no real loss, and after a cleaning the braking surface really isn't that bad they seem to be worn about half way give or take a bit.
