The Flite saddle series has always been associated with advanced comfort, innovation and design so it wasn't a surprise when Selle Italia decided to bring the Boost Superflow design to the Flite. The short saddle concept, or Boost is just 248mm long, but carries the current Flite top shape and leg glides. As a Kit Carbonioo saddle it carries a carbon shell strong an resilient enough to maintain the Superflow cut-out, but also features the Carbon-Keramic 7x9mm oval hollow rails. This combination results in most of Selle Italia'a lightest versions of saddle models, and this Large width option weighs in at just 162 grams. Not super light by SLR standards, but darn light for a Flite.

The Boost short, or compact, saddle concept delivers a more consistent seating zone with better support and pedaling platform that ensures power transfer throughout the pedal stroke. The design discourages much fore-aft movement, which is needed in the case of the Superflow cutout, a large open channel allows more airflow while reducing pressure on and around the sensitive perineal zone. The shape lifts the sit bones and allows the leg a clean path down to the pedals. Is it the right design for every cyclist? Of course not, but it does appeal to a great many riders who are looking for these features. If you are familiar with the Selle Italia idmatch fit system, the 145mm wide Large version of the Flite Boost Kit Carbonio Superflow is an L3 and recommended for cyclists with a "wide" intertrochanteric (sitbone gap) distance and high pelvic rotation, who develop high levels of pressure on the surface of the saddle.
