Yesterday, about a mile from home, I discovered that the upper shaft of> my V2 Aero 150 rollerski brake (where the brake connects to the "calf> cuff") had shorn off. And, as luck would have it, I discovered this> while motoring down a fairly steep hill. When I could cruise to a halt,> I inspected the brake and found a metal part had completely shorn off.> Anyone had a similar experience? I'm working on getting V2 to sell me> (give me under warranty?) two pieces of the brake assembly so I don't> have to purchase the whole thing for about $75. Anyone been able to get> pieces rather than the whole?
