Bottom-bracket and cassette lockring wrenches in multiple tooth profiles and sizes — heat-treated steel heads, two-component green handles, laser-marked sizes.
The RT-BB Series covers the full range of bottom-bracket and cassette lockring fittings: each wrench is matched to a specific spline or notch pattern — splined BB cups, notched lockrings and external-cup styles — so the tool seats fully instead of skipping under load.
Heads are cut from heat-treated tool steel and sized for a positive, full-depth engagement in the lockring; the range includes the common spline counts and pin/notch patterns used on Shimano-style, Campagnolo-style and external BB systems.
The two-component handle pairs a stiff core with a soft green outer grip that stays comfortable under a heavy breaker-bar load, and each head is laser-marked with its size for fast tool selection at the bench.
