- RR1.5 stems are designed with a low stack height and negative rise for road bikers looking to lower their handlebar position. They are made of high grade aluminum to achieve the perfect balance of strength, stiffness and low weight. The body is 3D forged from and advanced 7075 alloy and the broad four-bolt face plate design better distributes stress and lowers the clamping force required to secure the handlebar.
