The Vector Evo Streem saddle has a unique carbon-reinforced thermoplastic rail that works with the Vector Wing system to distribute stress and manage shell flex. This smart design offers superior compliance over traditional carbon rail saddles, but must be used with Ritchey's LINK seatpost system. When combined with the LINK post, the triangular rail material has qualities that absorb energy and diffuse stress and allow the saddle to follow the rider's motion, thus creating a tuned ride quality.

The saddle enjoys a flat profile across the back of the saddle to the front and features a thin and dense padding profile with a durable microfiber cover.
