Jason L. ★★★★★

The 12mm guide pin makes a huge difference when working on my thru-axle bike—no more slipping or misalignment. It feels solid and well-machined, and the lockring came off smoothly on the first try. Exactly what I needed for a hassle-free cassette swap.

Kevin ★★★★★

Finally a lockring tool that doesn’t slip off when I’m torquing it on a thru-axle hub. That 12mm guide pin keeps everything perfectly centered, and the steel body feels solid enough to last years. Took me less than a minute to swap cassettes on both my bikes.

Riley ★★★★★

The built-in 12mm guide pin makes this lockring tool much more stable on my thru-axle hubs than the older version I used before. It fits securely and removes cassettes without any slipping.
