Thank you for viewing. This is the Cateye Bluetooth Speed/Cadence Sensor ISC-12. There are a few minor scratches and scuffs on the arms, etc., from use, but it's a beautiful item without any noticeable damage. Please check the photos for the condition. I have confirmed linking with a cycle computer and app. I will include cadence magnets (unobtrusive pedal coaxial mounting type: 16mm x 2mm thick, 2 pieces), a rubber base, and tie-wrap bands. A wheel magnet is not included, so please prepare one.
