Tom Ritchey has been riding off-road and designing mountain bikes and components for more than forty years. He knows a thing or two about how comfort and confidence combine to help deliver a great mountain bike experience. He designed the new Python Trail grips to offer unmatched control, comfort and confidence for everything from epic XC days to shuttle runs at your local mountain. The heart of these new grips is Tom's patented Python self-tightening helical core design. With a spiral inner grip surface designed to literally constrict around the bar when the grip starts to twist, the Python grips ensure no slippage in even the most gnarly conditions. Fastened into position with an integrated lock ring, the ergonomically shaped Python grips also feature triple-density polyurethane that provides welcome support for your hands.
