Crown / Samducksa ST-35 Tension Grommet
Crown 300-series levers don’t use a metal return spring. Their centring tension comes from a rubber ST grommet, and the number tells you how stiff it is: lower is softer, higher is stiffer. ST-35 is the tension found in levers such as the CWL-309MJ-DX ST35.
Use it to replace a grommet that has worn soft over time, or to swap in a different feel on a compatible Crown lever.
