About a month I bough a new cycling computer a Bontrager Node 1 and about two weeks after having it I started to notice a syching problem between the unit and the sensor in the fork. Yesterday I rode in a 50k race in which the sensor first synched with the unit at the car but at the start line would not synch. This particular unit you have to wait for it to turn off before you can resych. At 8 attempts to resych during the race I gave up. My question is have any of you experienced this with this unit? what should I do to fix it?
