Balancing design, materials & manufacturing techniques allow the Kink Bold HRD to truly be a solid & 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, & a traditional 6 bolt system. Chamfered edges & radiused corners give them stem a clean look & knee friendly design. section Product Specs TYPE: Top Load REACH: 50mm RISE: 32mm CLAMPING DIAMETER: 22.2mm WEIGHT: 303.3g (10.7oz)
