Ohlin's DR line features the Divided piston and Rebound adjustability. Unlike standard gas over oil systems, Ohlins features a specially divided internal piston which keeps the gas and oil separate. This provides exceptionally consistent performance and avoids fade from use. The external Rebound adjuster allows you to tailor the shock to your preferences and customize the feel for each ride. Heading to the twisties? Give the adjuster a turn to the right which restricts some oil flow and gives an aggressive feel, great for performance. Need maximum comfort for the long haul? Twist it to the left to increase oil flow and provide a comfortably plush ride. Finally, the hose mounted hydraulic spring preload adjuster makes the adjustments easy to fine tune on the fly.
