The Rockrider XC/AM saddle has an Ergofit system for greater comfort while pedalling. The height of the dropper seat post can be adjusted using the control on the bike's handlebar: 120mm of travel in size S/M and 150mm in L/XL. The ability to lower the saddle in a second with a single press of the thumb is a real advantage in All Mountain biking.

Understanding sizes and measurements
Height ranges are reported by the manufacturer. A matching range is a starting point, not a guarantee of fit. Your proportions and bike setup also matter.
Reach is the horizontal distance from the bottom bracket to the top of the head tube; stack is the vertical distance.
Positive values mean more reach or stack than the reference size; zero means the same measurement. Missing values are not estimated.
Enter your height to highlight matching ranges.
