Winner of the Eurobike Award and many other comparison tests, our knee-shin combo has benefited from a lot of brainpower: we wanted to construct a pad that offers the best protection but at the same time enables you to pedal uphill as if it weren’t there. The patent-pending ION Tectonic_Fit is the key – overlapping and sliding protection panels keep the pad close to your knee at all times but guarantee maximum freedom of movement at the same time. Super_Perforator_Neoprene for additional breathability. Asymmetrical side padding for protection from impacts and top-tube contacts. The main SAS-TEC performance padding is famous for its cushioning characteristics. The K_PACT_SELECT is your reliable partner for home trail rides, bike park adventures and high-speed backcountry descents! Anti-bacterial treatment.
