The speed reducers to upgrade your rollerskis – classic and skating.

The speed reducers help to provide constant resistance on your wheels – for strength training or roller-skiing in long and constant downhill areas. You can choose the resistance with a screw. It’s possible to give up to 40% resistance on the wheels of the rollerskis.

The speed reducers have a wide roll to brake skating-wheels and wide classic wheels, too. We ship the speed reducers as pair inclusive 6 mounting screws. It’s important to have a flat rollerski-frame to install the speed reducers. You have to use them for the front wheels and it’s important to uninstall the mud guards.

You can equip skating rollerskis (80mm up to 100mm wheel) and classic rollerskis (70-80mm wheels) with the speed reducers.
