Well over a decade ago, we set out to make the best premium headset on the market. With our 110 Series, we did just that, utilizing optimal materials, the most effective seals and the best aesthetics.
With the flexibility to purchase complete assemblies or separate Tops and Bottoms, tops are available in either short (9mm) or tall (15mm) stack height bearing covers, the 110-Series offers a premium solution for nearly all straight and tapered configurations on the market today. From Integrated (IS) Tops to External Cup (EC) Conversion Bottoms and everything in between, you can mix and match your headset purchase to best meet your needs.
We are a Seattle, WA based outdoor gear store with a mission to make climbing, backpacking, skiing & mountaineering accessible and enjoyable for everyone.
