The Merritt Non-Stop cassette hub is a clean and simple looking cassette hub that packs more in than you would expect! The Non-Stop hub has a full bushing 120 tooth micro engagement 9T driver with 3 multi-tooth pawls, and precision Japanese bearings in the CNC’d 6061 hub shell. It is faster, smoother and rolls longer than most micro engagement hubs that rely on 6 pawls that are offset and cause unnecessary drag.
