A step change
"The seat is as predicted a totally new way of sitting on a bike and takes a few rides to get used to. But it works perfectly at removing pressure. The big thing is its positioning on the bike. Which ISM indicate on the packaging but need to make it more prominent on their web site. Typically these seats need to go backwards 50 to 75 mm compaired to a conventional seats nose position. I have had to change out my seat post to a 30mm setback to get it right for me. But only found this out once the seat arrived."
