Renthal Black Full Diamond Firm Compound Trials Grip features Renthal single compound grips. They are available in 3 different patterns. Each pattern is available in 3 advanced synthetic rubber compounds. This gives an optimum combination of strength, tackiness and shock absorption to suit every riding condition and individual style. The firm grip has the same feel as a stock grip. It is very strong and has very good resistance to tearing and abrasion. The soft grip is extremely soft, it gives a very comfortable ride, great feel and reduces the chance of blisters. However, because the grip is so soft it wears quickly. The medium is a compromise between the two.
