A quiet passenger under the bottle cage

An AirTag or UGREEN FineTrack holder that rides between the frame and the bottle cage, held by the cage’s own bolts.

Your bottle cage is already bolted to the frame. Slip a small two-piece holder underneath it and a tracker can ride along, out of sight.

  4. Fit the two M5 screws

    Fit the included screws through the cage and holder into the bosses. Their clamping force holds the two halves shut. Follow your bicycle maker’s tightening guidance.
