The DT Swiss RWS Plug In system allows for quick and easy removal of the RWS lever from your DT Swiss axles, leaving a clean, lightweight, and aerodynamic profile. The lever is secured by a locking mechanism and will not fall off, giving you the option to ride with or without it. If the lever is not readily available, the axle can be installed or removed using a standard 6 mm allen key. The lever's position can be adjusted by simply lifting it away from the bike and repositioning it as needed to ensure a neat fit. It offers safe and easy operation. Life is better on a bike with DT Swiss.
