Using my MarlinX
Connect the MarlinX to attachment 1 making sure the light is closest to the head and is visible.
For the most accurate graphs, make sure you are wearing a tight tech top or lycra and attach the MarlinX to the centre of the backend as high as possible.
If the top is loose it may cause a bounce on the graph at the finish.
Using attachment 2 - zip tie the attachment to the blade, so that when you add the MarlinX it will be flat on the recovery and turn square with the blade face during the drive. When attaching the MarlinX make sure the light is closest to the handle.
Using attachment 2 zip tie the marlinX attachment to the under carriage of the seat..
The attachment the MarlinX so that the light is facing upwards.
