You already have an awesome set of wheels.

they have excellent roll inertia (heavy weight?)when cruising but a real pig to climb

Far far cheaper to go on a diet to shave those few 10s of grams off.

Assume you and your bike is around 80 kg, combined, then an extra 400 g, whether on your wheel or head or gut or anywhere else is 0.5% of your total mass, and will slow you on a steep hill around 0.5% of your total speed, or, in other words, for a half-hour climb, around 9 seconds.

I don't think you can even feel this difference, especially since human body mass varies, day to day, by at least twice this amount.

However, it's real time lost in a race, whether or not you go on a diet. The Williams wheels, for example, come with ceramic bearings, and are lighter and quite affordable. However, I don't expect you will notice the difference without multiple trials with a timer, averaging times to reduce the statistical noise.

Pro Lite Stelvios are great. They are an area favourite over here. More aero than Ksyriums. Not heavy. Nice rear hub. You get a lot of wheel for the money, considering what they come with. The tension is superb too. Least problems out of any wheels I've touched, my Ritcheys included.

Im 90kg 🙂... Ive borrowed a pair of standard wheels that weight around 1400g, Easton ascentII's I believe and have riddden them for 2 rides whilst my freind was trying Campy Shamals and have noticed very much easier climbs and less fatigue on the same araes where I cycle so i do believe that the extra 400g shaved off at the wheel and/or better rolling hubs in the wheel do make a significant difference.🙂

which Williams wheel would u be referring to ? thks

Members of my club (Webcor/Alto Velo) have reported to like them: I wasn't thinking of any particular model.

Here's a review:

For more money, a good option is Dave's Speed Dream wheels. Dave's a custom builder who places a high priority on durability. I bought a rear wheel from him, 28 spoke, and it's rock-solid, light but not super-light @ 900 grams (too bad I switched to Powertap soon after...)

I hate to be a skeptic, but you're comparing highly subjective impressions of two entirely different riders over only two rides in the "same area"?
