What Our Gearhead(R) Experts Are Saying: "I've been using the Transiro Aeris R5 on my race rig and it's been a total game changer for short-course racing. The shape keeps me stable in aero, the cutout relieves pressure just right, and the padding hits that sweet spot between firm and forgiving. It's designed for race-day output but stays comfy the whole way."When seconds matter and power output needs to stay maxed from start to finish, we trust the Fizik Transiro Aeris Short Distance R5. Engineered through cutting-edge research into cycling aerodynamics and comfort, this saddle is a race-day essential for triathletes and time trialists looking to stay locked into their aero position with confidence and efficiency. The pressure-relieving cutout transitions into a supportive channeled nose, offering stability right where we need it when we're pushing watts. Type-1 padding is optimized for time in the bars-thicker up front for sustained aero effort, slimmer at the rear for solid support when climbing or cornering out of the saddle. Add in aerodynamic adjustability, optional hydration integration, and UCI compliance, and the Aeris is ready to chase PRs across the tarmac.
