wheelset rider limits

when manufacturers give rider limit values, does it mean per wheel or over both wheels?

well if that's the case, how do they factor in rider's weight distribution?

I take them with a grain of salt. Or more like a pound of sugar. I bought a pair of wheels where I was at the high end of the limit on Easton Ascents. I then gained about 30 pounds over the years and continued to ride them without any ill effects. I also ride on the streets of NYC, not the smoothest of places, but I am careful about bumps and potholes. The wheels are fine.

Good questions.

Informative answers.

Thanks.

The same can be said about my claimed weight. I tell my wife that I'm at ~190-200 lbs. She, of course, knows that it actually fluctuates between 200 - 210.

Yes. It's the weight limit for the rider assuming he's on a normal bike with two wheels riding on average paved road surfaces. It's not a hard limit such that the wheels will immediately assplode if you're a lb over the weight limit. Engineers design the wheels for a given safety factor and specific conditions and come up with a specific number. In reality, there are a lot of variables and somebody under the limit may damage the wheel and somebody over the limit may ride for many thousands of miles without issue.

It's a rough average and as some have said, there's a safety factor built in. Wheels designed for, say, a 180 lb rider will see momentary loads far exceeding that due to pavement irregularities. cornering loads, especially on favorably crowned road, etc. The wheels don't just fold up if slightly overloaded, but a wheel pushed to its limits regularly should never be expected to be as durable as something built with more reserve strength.

By rule of thumb. It isn't rocket science, nor is the weight limit some critical number above which failure assured. There are other varialbles such as riding style, terrain and pavement that also come into play. Consider limits as guidlines, with built in safety margins. As you approach or exceed the limit, the risk of shorter than normal wheel life increases. The more you go above the limit, the more the odds go more against you.

Begs the age old question: "Do these wheels make my ass look big?"

The wheels are grunting to themselves that your ass is too big!

Why bother? There is most likely a safety margin built in.
