Clean the surface of your driveside chain and seat stays. Remove the backing liner from the roll in lengths of about 150mm to 200mm at a time. Snip a little off the sides on the free end of the tape to make a wedge shape to make it easier to pin down to the frame with your thumb. Place the end onto your frame and stretch and wrap it around (over and under the stay) creating an overlap of 1/2 to 2/3. Stretching and overlapping the wrap activates the self fusing properties of the tape. Repeat this 'stretch and wrap' action until you get to the end of the roll and then press your thumb firmly on the end to bond it to the wrap beneath. Install complete. Ride bike. Smile.
