Fizik | Transiro Mistica Kium Rail Tri Saddle

Stay locked into the aero position and keep the power flowing.

The Fizik Transiro Mistica Kium Rail Tri Saddle is a triathlon-specific saddle built around a stubby, noseless shape that supports comfort and performance in the aggressive aero tuck position. Its extra-long Kium alloy rails provide a wide range of fore/aft adjustment, making it easier to find the right position for the fastest part of the race.

A redesigned channel improves weight distribution across the sit bones, while the seamless, friction-free nose construction improves comfort and an extra-grippy surface helps maintain stability. The carbon-reinforced nylon shell is paired with a redesigned carriage kit for greater versatility and easier installation.
