Rated 5 out of 5 by light and comfy great saddle, let you spare few grams vs railed ones I use it for daily commuting, not much wear for 6 month and quite comfy on rigid hybrid bike Proprietary mount is a bit of concern maybe - still 5 stars, worth bying 20 September 2012
Rated 5 out of 5 by Хорошо, но с подставами. Это седло разработано для того, чтобы у вас текли слюни. Америкосы смогли возбудить покупателя (да-да, седлуха USA), а чтобы у вас они текли ещё больше, сёдла выпускаются с нестандартными (для России) диаметрами подседельного штыря, который, к тому же, имеет уникальное крепление от SDG. Так, например, на российских Forward'вх тот самый диаметр 28.6 мм, а тут (штыря) - 27.2. В общем, докупайте переходничок и штырёк - и будет вам счастья, 16 June 2012
Rated 5 out of 5 by great!! awesome saddle! ultra confortable! i use it on my downhill bike, its light, but not very strong, because of the "flex", mine i already broken after a very big crash i had... but its only cracked from the rear end of the saddle, so you dont even notice it, only if you see it, anyway, im super happy with it!!!! my ass loves it! 11 June 2012
Rated 3 out of 5 by Not Great Originally, I was happy with the saddle. Not the most comfortable, but I got a bit of a deal on it, and it looked pretty awesome. 1 year on and I'm looking for a new saddle as this one seems to have lost its support in the middle. When I sit on it now, the middle of the seat sags down and makes contact with the I-Beam base, which puts extra pressure on man bits. 11 April 2012

Rated 3 out of 5 by J'ai cette selle depuis 4 mois, et je l'ai essayé sur un semi rigide et un tout suspendu. QUE DU BONHEUR !!! super confortable ! excellente finition, l'absence de coutures fait qu'il n'y a aucun frottement ni échauffement lors du pédalage. Le système I beam est efficace et m'a permis de gagner 200 grammes sur les deux bikes. 26 March 2009
Rated 5 out of 5 by selle et tige de selle SDG usa superbe selle rapport qualitée prix et poid ,confortable pratique pour le réglage et le démontage rapide a effectuer avec sa tige de selle adéquoite. 23 February 2009
Rated 5 out of 5 by Excellent saddle in very good price I have got this saddle a few weeks ago and I am very satisfied from this poduct and also from the I-beam idea. I use my MTB in Mountain and City ride and I have to admit that that saddle fits my body much better than my previous SelleItalia its hard but stable and if you spot your body on the right position of the saddle (its natural and easy to do that) then you will be in perfect match with that saddle. I-beam is an excellent idea that is light and STABLE without giving you the impression that its going to move back and front and if you combine with the FX you will be pleased so much 08 February 2009
