DT Swiss HWGXXX00S2870S Ratchet EXP Service Kit
DT Swiss' HWGXXX00S2870S Ratchet EXP Service Kit is offered as the best-in-class choice for thru-axle e‑bike hubs because it replaces the precision Ratchet EXP components that handle higher torque and heavier loads without sacrificing engagement quality. While it carries a premium price, its machined ratchet ring and exact-fit spare parts deliver longer service intervals and better durability than economy kits like Novatec, and it provides a more serviceable, high-performance alternative to some OEM Shimano kits.
