I do a lot of time trials including 10, 25, 50, 100, 12 Hour and this year in July I also had a 24 Hour TT planned. Because of the discomfort last year I was using a sanitary towel to try and remove some of the pressure. I then lent an ISM Racing saddle from my local bike shop and this certainly relieved the pressure but I found it a little wide. I reviewed the saddles on the ISM website and ascertained that the PN1.0 looked slimmer. I contacted ISM and applied for their demo program and they sent me a PN1.0 saddle to try. I used it the week before my 24 Hour TT on a 45 mile ride and it seemed ok. The proof would be the following week on my 24 Hour Time Trial which I achieved 374.025 miles and the saddle did its job. I can therefore recommend this saddle 100%. I am now looking forward to receiving my new saddle.
