Selle San Marco ASPIDE OPEN-FIT- primarily designed for the road for people with a healthy build and normal to narrower pelvis. It will also suit hill climbers due to the longer and narrower toe box along with the support it provides to the back of the pelvis during climbing. The hole is standard, so average hip flexibility is assumed, where there is not extreme emphasis on intimate relief.
Dynamic- a basic design with a carbon enriched shell, Biofoam cushioning, Softfeel surface and Manganese skins. It is designed primarily for beginners or hobby riders with lower annual mileage.
