The heir apparent to the XC Fire, the Cinder incorporates our newest compound technology ZSG Ultima. This compound performs unlike any other that weÅfve ever developed. Hot or cold, wet or dry, ZSG-Ultima is up to the task. Add to this our progressive multi-height knob configuration and the Cinder just rolls away from the Fire XC in terms of overall performance. ASB keeps away the pinchies and "gAbsolute F&R" design makes it work well on the front or rear.
