The G15 is the big brother of the familiar G13 and comes with 145mm travel at the rear. Designed for the enduro lifestyle.

The G15 is the big brother of the familiar G13 and comes with 145mm travel at the rear. Designed for the enduro lifestyle, the G15 can perform exceptionally well whether the degrees of the mountain is set in the positives or negatives.

All “G” models have been completely redesigned including a new swingarm and BOOST dropouts which are lighter and stiffer. Likewise, the suspension response has been fine tuned with the use of quadruple sealed ball bearings. Sealed for the applause of the people taking the ION-G15 on wet and muddy winter rides. The proven NICOLAI shock lever has been pushed through many FEM strength calculations in order to reduce the weight while keeping the same rigidity. Although our 5-axis CNC machine now runs a little longer, as a reward it’s lighter.
