Mountain Biking - Wheelset Question

I am seriously considering changing out my wheelset, tell me what you think.

I ride an 03' Enduro frame that I built up. I decided to go with handbuilt Sun Rhyno Lite XL disc rims with XT hubs - weigth 2350 grams! I have been running Panaracer FireXC Pros in a size 2.1.

I weight a fit 210 lbs and ride aggresive XC/all-mountain - whatever it is called at this moment. I am aggresive, but keep the drops to under 2 feet. Coming from a set of Mavic 222's I noticed a big difference in weigth on the new wheels. Now the Rhyno's have been pretty bomb proof but I was thinking of switching over to some Mavic X317 w/XT hubs - 2010 grams. The new setup would save me about 300+ grams.

Would the 300+ grams make a noticeable difference in my ride, especially uphill. Keep in mind I am not a weight weenie, but I would like to maximize my pedaling power. Or do you have any recommendations, something around 200-250.

Thanks-

1 pound on the wheels is 3 pounds on the frame! Rotating weight makes a HUGE difference. You'll accelerate faster and use less energy in the long run. I wish my wheels were a bit lighter.. I was thinking of going with a set of Crossmax's until all this **** came up lately.

300gr is a hefty amount of weight to save off . But i am very sceptic about the X317 rim. I am exactly the same weight as you are, 210lbs, 6ft3" riding aggro-xc/lightFR/allmountain etc etc etc. I suppose that the F219 rims are the way to go.

Yeah, I'd be skeptical of any lightweight wheels. I personally could get away with running super light wheels with no problems because I'm a light rider, although agressive. But if you're fairly agressive and a pretty big guy, I'd say go for something a littler tougher.

Jim311 is right about this, at 210 you want a little more wheel than someone who's 155. Shaving 300 grams at the wheels will make a noticeable difference in climbing. If you do go with a light wheel you may have to run a little higher pressure in your tires to ensure you dont damage the rims on even a 2' drop.

you could always try contacting Mavic by email or something and ask. You never know, they might be able to help you.

Thanks for the help, it is much appreciated.

Ride On.....
