yes you are right, this should be a much better system but I think more expensive .... I will look for that further ...
also more complicated as you have to take the tire off or doing it when changing the tire after 8.000 km. .....
I do not trust very much the SMARTCAP system .... don't really know why .....
but doesn't it have the same balancing problems ( this is 14 grams ! ) as the one I speak about ??
