Hi Smithy! It all had to do with my grip. I modified the handlebars and eventually changed to regular road bars. I also had to be very conscious of NOT gripping too tightly. Many years later and my hands are totally fine though I've logged thousands of miles on my bikes.

I haven't been on this forum in years, but I was still subscribed to this post apparently!
