Matter´s original one20five wheel has had a performance upgrade by way of the CHR core. The CHR core has been engineered to offer a more comfortable ride quality without sacrificing rolling performance. The one20five wheel utilizes the wider wheel profile for more comfort and grip. This is the perfect wheel for more technical marathon events with lots of corners and varying road surfaces. Available in F0 (88a), F1 (86a) and F2 (84a).
