Made from our high-quality C:62 carbon, with a short and stiff rear triangle and a tapered head tube for optimal power transfer and direct steering. Typical CUBE: the AgileRide geometry offers a nice mix of agility and stability. But we haven't forgotten about comfort either. You may have noticed the slim seat stays? But the comfortable 27.2 mm seatpost also contributes. This bike is fast without tiring you out prematurely.<
