Combining the 34mm diameter with ribbed texture creates maximum shock absorption in ESI's lineup. The Ribbed Extra Chunky merges the cushioning from the larger diameter with the traction and damping benefits of eight lengthwise ribs. If you have large hands or want the most vibration isolation ESI offers, this grip delivers both through the thick silicone body and the compressible rib structure.

Each rib creates a raised contact point that compresses under grip pressure, adding another layer of cushioning beyond what the smooth Extra Chunky provides. The valleys between ribs also channel water away from your palm in wet conditions. Your fingers settle into these valleys, which prevents hand rotation during hard cornering or steep climbs when you're pulling on the bars. The ribbed texture provides mechanical grip that works alongside the silicone's natural tackiness.

The silicone construction eliminates the need for lock-on clamps. You install these grips by sliding them onto your bars using rubbing alcohol as lubricant, and they stay put through friction once the alcohol evaporates. The material maintains grip in wet conditions without feeling sticky when dry. The silicone gradually conforms to your hand shape and grip position over time. You can clean silicone grips with rubbing alcohol or acetone when they get grimy, which would break down rubber compound grips.... Read More
