Yeah I can see removing a wheel set and perhaps moving it to the back to make room, otherwise I could mount something up on the front skis.
I do a lot of running on hard pack and sometimes bare ice end of March. My main reason for installing these was to lube the sliders. Yes this is a fan cooled unit, just thought I would find a way to cool the sliders.
I don't ride much anyway, mostly to my ice shack on Lake Winnipeg so at best given the terrain I can only go 25 - 30 km before the bumps an ridges slow me down and beat up the tobbogan I'm pulling.
