Late in a long, rough descent, the PNW Range Grips soften the feel through the bar with a thermoplastic rubber compound at 25A durometer and micro-fin patterning that lets the palm sink in. These soft mountain bike grips add a gridded underside with a raised waffle section for extra grip under the fingertips. What Our Gearhead(R) Experts Are Saying:"After a season of rough trails the grips still felt soft and stayed tight on a carbon bar, because the closed-end single-clamp design holds with a torqued clamp and no glue or hairspray. I check the handlebar clamp diameter before ordering, since some kids' bars use a narrower one."
