Balancing design, materials and manufacturing techniques allow the Kink Bold HRD to truly be a solid and affordable stem. The die-cast aluminum body is paired with a forged 6061-T6 aluminum cap, providing additional strength. A counter bore in the stem body allows the fork cap bolt to thread down flush for a clean look. The classic 50mm reach comes with a comfortable 32mm rise, and a traditional 6 bolt system. Chamfered edges and radiused corners give them stem a clean look and knee friendly design.
