It’s because of how a hardtail behaves; there is no suspension movement at the rear, so as you use travel at the front the whole frame effectively pivots around the rear axle, causing the geometry to change. The more suspension travel you have at the front, the more the geometry can change. Running rigid forks would give no geometry change but obviously a harsh ride. Long travel forks would give the best ride, but they will allow large geometry changes which make the bike feel unpredictable. So we have chosen what we believe is the best balance; enough travel to give a supple ride but not so much as to cause the bike to feel unpredictable. It might seem like our specifications are short compared with today’s full suspension bikes, but rest assured that we’ve selected the correct travel for our frames.
