Park Tool Single Speed Wrench - SS-15

Single-speed and fixed-gear riders carry fewer moving parts on their bikes — their tools should follow the same logic. The Park Tool Single Speed Wrench SS-15 is a forged steel multi-tool built around the handful of adjustments a single-speed rider actually needs: a 15mm open-end wrench for axle nuts, a lockring tool for track-style freewheels, a tire lever, and a bottle opener.

The slim profile fits cleanly into a jersey pocket or saddle bag, and the forged steel construction means it handles real torque without flexing. It's a tool you grab because it does exactly what you need and nothing you don't.
