I haven't been on this forum in years, but I was still subscribed to this post apparently!
Hi!
I must be the 3rd or 4th pianist in this forum to experience the same thumb pain! Thank you very much all for your helpful insights and especially for KnottedYet for the update after several years - this gives me an idea to probably change my handlebars. I'm off to the bike shop again to see if the "roadster" handlebar will be good to use on my mtb! I've tried my daughter's roadster which we won from a raffle draw and the handlebar indeed is much more comfy than the straight mtb ones that i have... Thanks again
