I just want to give two thumbs up (or, should that be two butt-cheeks up?) for this saddle. My bike came with the 143 and it was KILLING me. Swapped it out for the 130 and wah-lah!

Yes, as maillotpois says, "every butt-y's" different. I suggest getting your sit-bones measured so you can be sure to get the right size saddle. It makes a WORLD of difference!
