DT Swiss 3-Pawl Boost Freehub Body
A best-in-class freehub body for Boost hubs, the DT Swiss 3‑pawl design balances low weight, proven durability, and straightforward serviceability. It holds its position by offering reliable engagement and a cost-effective, lightweight aluminum construction that undercuts many boutique alternatives while matching performance for most riders. Compared with the high-engagement, premium-priced options in this list it delivers excellent value, and it is a lighter, more serviceable alternative to some steel-driver Micro Spline solutions.
