  1. I sent you some comments the other day after putting the first 40 miles on this upgraded drive train. I now have 70 miles on with a bit of hill climbing.
    Because I was already using a set of jockey wheels with 12T x 14T and ceramic bearings, I wasn’t expecting a noticeable improvement.
    I was blown away!! Your wheels and cage made a greater improvement in pedaling efficacy than I thought possible.
