The Transiro Mistica's channel design enables better weight distribution across sit bones and the new seamless, friction-free nose construction delivers improved riding comfort, while an extra grippy material provides maximum riding stability. The stubby, noseless shape of Transiro Mistica allows comfort and pure performance in the aero tuck position required for your fastest triathlon cycling leg. The extra long light, strong Kium alloy rail on this model allows for maximum adjustment fore and aft to promote the perfect aero riding position.
