Seba X2R Rockerable frame for 80 mm wheels

This frame is suitable for inline skates from FR, Seba, Rollerblade and Flying Eagle.
You can turn your 3-wheeled inline skate into a 4-wheeled inline skate with this frame.
The frames are sold in pairs.
The eight axles and also eight spacers are included.
The axles of the first and last wheel are asymmetric so you can choose between a normal set-up (all four wheels touch the ground at the same time) and a "banana"/rockered set-up (only two of the four wheels touch the ground at the same time). The latter set-up is suitable for practicing slalom tricks.
