Skike WAHIA is an universal brake for any roller ski - regardless of brand, material and design - and for all Skike Rollers. The Skike WAHIA works completely detached from the roller device - because this brake is not attached to the device but to the shoe. This unusual, yet revolutionary approach makes this brake the universal choice for any commercial roller ski. It can be used with any ski binding and its associated shoe, any shoe-size. The main advantage is that the user has quick and complete control over the deceleration without making concessions to his way of riding.
