Intended for marathon efforts in the mountains, the Fizik Gobi M3 Saddle features a slightly waved profile for supreme comfort while the premium construction keeps weight low & performance high. The Fibreglass Composite shell is exceptionally light & features Wing Flex for freedom of thigh movement & Tail Flex for easy transitions on & off your bike. A mixture of Microtex & Cordura cover the shell for a high wearing finish that looks good for longer. Fizi:ks Integrated Clip System provides a simple, tool free way to mount a range of Fizik bags & lights with ease. This version of the Gobi M3 is supplied with Fizi:ks unique K:ium rails which offer performance & weight advantages over standard cromo rails without increasing the price like titanium & carbon rails.
