An essential part of your power production, the Fizik Antares R3 Carbon Rail Saddle is a lightweight platform for cranking out the watts. Wider and shorter than the Arione, with a slightly rounded off transverse profile and a slight kick at the tail, the Antares is ideal for riders who don't like to stray too far from their position over the pedals.Weighing just 15 grams heavier than the carbon shelled Antares R1, the R3 version uses a fiberglassthermoplastic shell to save a few bucks with hardly any weight penalty. But let's focus on what the Antares R3 does have.. Still present is Fizik's braided carbon rail structure, which slashes weight while boosting comfort. Also here is Fizik's Wing Flex Technology shell, with tuned flex areas at the forward edges of the saddles sit zone. These zones flex to accommodate a range of morphologynarrow hips, big thighs, all are welcome and comfortable aboard a Fizik Antares R3.
