In the interest of full disclosure: I am not a big fan of "hybrid" bikes. (Search my username and the word hybrid and you can see some of my screeds...)Originally Posted by maxrep
I enjoy my mountain bike -- it is not a road only thing. Just hybrids are not enough to go tear it up in the trails, and they are inefficent on the road. The discomfort of road bikes goes away with a little time in saddle. And if you want to ride on dirt paths and stuff too, get a mountaing bike and put slicks on it. OR Somebody posted on here the other day about a Specialized cyclocross bike. I really liked that as a "hybrid" (In thruth it is more a special niche product, but a great choice for a clydesdale who wants to ride mostly roads.)
All that aside, my road wheels are narrower and lighter than your hybrid wheels and they have carried my 270 pound (down from 350) about 2,000 miles. They are fine.
Ultimately, no matter what anyone says, once you get it home are you going to want to ride it? If the answer is "Yes!" It's a good choice. If it is "Maybe..." then find a bike you are excited about.
I'll stop preaching now. Good luck. And remember, it's bike riding. It is supposed to be fun.
