The black fizik Vento Arione R1 Adaptive is the 135mm width with 3D-printed zonal cushioning. The padding retains a relatively flat top instead of a pronounced central surface cutout, above the long Arione profile.
A carbon-reinforced nylon shell is supported by oval 7 x 9mm carbon rails. Length is 284mm, with a stated 184g weight for 135mm. The rear rail towers allow a long positioning section; follow the clamping marks and confirm oval-rail clamp compatibility.
