Overview
About this bike
Marlin 8 is a confidence-boosting trail bike with updated geometry that gives you more control on singletrack without skipping on features for everyday use, like mounts for racks and a kick stand. It's built for years of progress thanks to 12-speed SRAM shifting, and an upgraded RockShox air spring suspension fork.
