I'm going to try riding one of my road bikes on the mup today. Yesterday I ride the mtb around the neighborhood for 1.5 hours. Ribs/back didn't bother me at all but the groin/hip thing hurt when I stopped, stood on the pedals, or just getting on or off the bike. I lowered the dropper which helped. Didn't seem to cause any negatives, so we'll see about the road bike this a.m.
