I opted for the Cleveland wheel and brake conversion. However, when using wheel penetrating skiis, they require 6x6 tires and I really don't want to brake down my 8.5 x 6's each year. Guess I just don't want to screw up a tube. Talked to the tech support at Cleveland (Parker) and asked if any other wheels could be used to replace the 40-60 Clevelands. New guy on the phone and he didn't seem to think so. However, I can't believe it. Anyone out there using anything else on their Cleveland W&B conversion?
