Miche Zero Point is innovative balance system for medium-high carbon rims to reduce the typical wheel unbalance effect of the valve weight. Zero Point effect is better appreciated when the speed is going over 40/45 km/h, and mainly in the long descents. In addition the comfort is improved: reducing the unbalanced wheel effect, this improvement should be also appreciated by general cyclists.
Zero Point is applied outside of the rim in the opposite side of the valve, in order to balance the valve weight.
That keeps your running carbon wheel smooth and round.
