I was at the bike shop the other day(looking at lights) and some kid comes into the store with his bike and looks around for a few minutes. Then a bike shop tech comes out to help him. He said his bike rides perfect and is light weight. The tech then asked why is it here? He said the Crank doesn't match the rest of the componants. His componants were all LX and his Crank was XT. The tech told him he's better off with what he already had. But the kid said it's too ugly......LOL....is this isolated or does this happen often?
