If you're building up a custom headset, you probably already know that the Cane Creek 110 Series houses some of the most premium options on the market. As the top tier line from a brand that only makes designer componentry, the 110 Series is backed by a 110 year warranty. No, that's not a typo, it's Cane Creek's actual guarantee on its designs. Giving you the freedom to assemble your headset exactly the way you'd like, the 110 series IS4128. 6 Short Cover Top comes tailored for head tubes with a 41. 1mm diameter and stem clamps with a 28. 6mm diameter. It's an integrated model with a total stack height of 9mm. While we wouldn't be surprised to hear Cane Creek crafted its headsets out of gold, the IS41 is constructed with far more durable 7075 aluminum, regarded for its resilience and low weight rather than its status as a precious metal, and it comes with sealed stainless steel bearings to deliver a smooth, creak free ride from now through the next century.
