The Wall saddle is designed with a taller and more vertical back support area to hold the rider in position more aggressively. This is a great setup for high output bikes like the new CVO as the Corbin saddle keeps you planted. Is it possible to get too much of a good thing? Not when it comes to support, so the Wall saddle has the option of a removable rider's backrest. In fact, this seat offers 15 inches of vertical support with our #BR backrest installed (shown).
