The Dimension R2 is Prologo's ergonomic high-performance saddle, part of the top range of the Dimension family. A completely redesigned tip — 40mm wide, 30% wider than the previous model — and a flatter surface through the centre favour a forward, aerodynamic position and let you use the full length of the saddle.

New EVA foam allowed 1mm to come out of the rear padding, cutting weight while keeping support. The PAS channel and perforated base mitigate pressure peaks under hard efforts.
