Mountain Biking - Wheelset weights

Will the average rider notice the weight difference in a finished rear wheel, as in pedalling energy efficiency........ for instance compare Mavic Crossland 1100g vs. Crossmax SL 915g

200 grams wont make a difference, instead of using money to save weight, try to save your own weight and it will make a significant difference.

Yeah make sure you defecate. That's an easy form of weight loss. :D

i dont know man... 200 grams is almost half a lb. this is a fair amount of rotational mass.

This is what I am concerned with since I am not a clyde. If the added weight is more in the rim, then it will be harder to spin up, but if in the hub, it will be harder to clear that last log at the end of the day......... It will be tubeless though and that is 200-300 grams.

I'd get a wheel that's as light as possible (considering it's UST) that you can afford. I don't think I'd be stingy on the wheels. What's wrong with tube clinchers? Pinch flats dont happen that often, and unless you're some freerider (who don't really care much for weight), I don't think tubeless is worth it for the money you're spending. My opinion, of course.

Yup, you will notice the difference when you accelerate. If you can afford it - do it. I'm not a big proponent for shaving grams in other areas, but a light (and strong!) wheelset is an area where it's worth it.

ANY rider will notice a difference between a heavy wheelset and a lighter one. Will a 200g difference be noticible? YES! Rotational mass is the best place to shave the grams if that's what you're after.

Rotational weight is where it's at. Or, shouldn't be, as the case may be. There is however a fine line between duribility and weight and riding style and type of bike blah blah. Will you notice 200g? It's hard to say, but without magazines doing any sort of scientific testing and bike shops not lending you 5 sets of wheels so you can test out for yourself which ones are faster, probably best to stick to theory and run as little rotational mass as you can.

Actually, I do believe there is a German website or magazine that does do scientific testing. Is it www.mtb-news.de???? I remember there being links to it in the weight weenies section of mtbr.com.

I would say that the cross max would be a safe bet.

and bike shops not lending you 5 sets of wheels so you can test out for yourself which ones are faster,

Actually, Mavic does have a Demo program that allows you to do just that. You can put down a deposit and use a set of CrossMax wheels for a weekend.
