Its the one thing ive struggled with since starting to road bike, on the mtb padded shorts no problem, on the road bike it doesn’t work. I’ve tried padded shorts, didn’t work. Padded Rapha Boxers slightly better for short rides long rides, didn’t work. Padded lycra shorts from DHB, better than the other 2 but still not quite right but I think its down to the size, going to order a smaller size in the shorts and see if that fixes this problem once and for all!
One thing I would say is get the right size, don’t be afraid to send stuff back, I haven’t and really should do I’ve got a couple of shorts I should of returned. Tempted to get some rapha bib’s but the only ones reasonable are “Team Sky” and tbh don’t really want those.
