The mANTis is our 29er and 650b+ compatible all mountain fully. With 140mm of rear travel and 130mm – 150mm travel forks up front the suspension absorbs most of what the trail throws at you, while the Rohloff & belt drive train results in a smooth and silent ride. In fact so silent that you can hear your tyres squirm when you’re hammering through the corners. The lower chain stay section is from aluminium and engineered to accommodate the concANTric bottom bracket section as well as the axANTer PM-R for Rohloff use. The top tube is lowered to maximise stand-over height.
