The Cane Creek Helm was born in the mountains of Western North Carolina, and is designed for aggressive trail riding. The Helm Works Series is the lighter, shorter-travel version of the Helm. The Work Series Helm is optimized for 120mm and 130mm of travel, built on 35mm stanchions, and weighs about 100 grams less than the Helm Air.
The 44mm offset version of the Helm allows you to shorten the trail and wheelbase on your bike, without changing the head tube angle. See Cane Creek's guide: here.
