DT Swiss Hub Seal Installation Tool

Install the driveside hub-shell seal on compatible DT Swiss Ratchet hubs with a tool designed to keep the seal aligned as it seats. The revised shape clears the oversized axles used by some Hybrid hubs.

Not for Ratchet LN 370 hubs: their seal is mounted on the freehub body rather than in the hub shell. Check the seal position and tool number in the hub service instructions.
