The SL “connector-less” system simplifies wheel changes: No more wires! Using a special dropout on your fork, the electrical connection is automatic: One pole is routed through the axle (and your frame), the other through an insulated ring that mates with a corresponding, insulated ring on your dropout. Simply insert the wheel, and the light is connected!

Framebuilders use these dropouts to build a fork for SON SL “connector-less” 12 mm thru-axle hubs (12 x 1.5 mm thread). Stainless steel to resist oxidation. Requires an SL connector kit for 12 mm thru-axle.
