Luna X5 is the optimum MTB saddle made for women. It is designed specifically to suit a woman's body shape and movement while riding off-road, with IschialFlex providing flexible support across the whole surface of the saddle to create comfortable freedom for the rider's soft tissue so you can ride longer, faster, harder and all in comfort According to the Spine Concept EVO system, the Luna X5 Large's maximum width of 153mm is best suited to riders with a lower power output to bodyweight ratio. The fi'zi k Luna X5 saddle's light, strong, corrosion-resistant S-alloy rail supports a carbon-reinforced nylon shell. Its central section is a laterally strong and stiff carbon reinforced co-injected nylon spine, which is bonded to thermoplastic elastomer side panels, that allow flexibility and movement when pedalling, and form to the rider's body shape. The ergonomic cut-out shape has been specifically designed to provide additional relief to areas of soft tissue particularly during long rides. And to cope in style with the demands of off-road riding, the Luna X5 has reinforced Microtex over its side panels, with Microtex Classic on the upper shell.
