Wrong. Not even close. There plenty of wheels on the market weighing more than 100-200 grams less than the SLX - which by the way does not have a rider weight limit either.

A wheel weighing 800 grams more is almost 2 pounds heavier. Obviously that wheel would be considered bullet proof, but the loss in performance would be huge. I'm sure the tipping point between performance and durability is somewhere well below an extra 2 pounds of weight. I do a lot of fast A & B club rides with guys who race Cat 4 and 5. Being a clyde, it's hard enough to keep up with these guys without ship anchor wheels.

I was a big kid, and I used to beat the snot out of cheap K-mart bikes. We used to jump our bikes off curbs, homemade ramps, etc. I have snapped cranks, busted frame welds, bent handlbars, etc. But I have never had a spoke break on even a cheap bike with low quality alloy parts. I really don't believe that finding a good, light weight high performance racing wheel that can take the "punishment" of a 220 pound rider who is not deliberately beating the snot out of them should be such a chore. For what I pay for these wheels and with all the advanced materials technology, I expect nothing less.
