- Place two silicone pads on the two-part bracket. Align the contours on the silicone pad with the grooves on the inside of the brackets.
- Place the two-part bracket with silicone pads on the selected tube, and tighten the screw until the mount does not slide on the tube. Note: Periodically check the tightness of the screw.

- Choose zip ties if the bracket diameter is incompatible with your frame.
- For installation in areas like the seat cushion, trunk, under the pedal, or front storage box, use double-sided adhesive tape.
