Cane Creek headsets with Hellbender stainless steel bearings with increased sealing elements and more grease in relation to the comparable 110 bearing. The Hellbender is our shop-favorite headset. We are located in the Pacific Northwest, and most of our riding is in the rain and mud. This means we are also constantly spraying and washing our bikes with a hose. The Hellbender has proven to be an incredibly durable and long-lasting headset in our very wet riding conditions. Hellbender bearings last noticeably longer than the 40-series headsets and much longer than OE style headset bearings. Designed to bridge the gap between the 40-series and 110-series headsets Insanely sealed for durability and long-lasting performance An excellent upgrade over the 40-Series headset, and a massive upgrade over OE headsets. Machined from 6061 T-6 aluminum Stainless steel bearings
