My buddy moved to Vancouver and gave me his SS wheel. Same gear ratio as my bike (52x20). I was running it as a bum bike ss(cassette locked into one gear.) I put it on my bike and took it out for a ride. I'm at least 5kms per hour faster with that wheel according to my bike computer. I guess a properly dished wheel actually does make a difference. Thanks for taking the time to read a pointless thread.
