Are shimano R500 wheels ok for cross racing? If not is there something else in that price range? Now that I have the bike I want I want to get the frame and build it up piece by piece for as little as possible but with decent quality stuff. My tri bike and a friends road bike both use the shimano r500 wheel set so I assume it would be ok for cross. I found a few on ebay for decent prices so I am just curious.
