I put a shock absorber seat post on my mtb, and left it a little loose in the adjustment, so it will move a little left and right while pedaling. Also put an inflatable seat cover on it. Takes some of the stress off my skinny butt. I also put an 8" handlebar stem extension and aero bars on it to relieve the numbness from the carpal tunnel syndrome I have in both wrists. OH yeah, and it's a cheap BB store bike. Let the hating begin.....LOL
