In context of the DS, the only choice for the integrated setup is the DuoTrap S version. Before 2015 there isn't a spot for the older DuoTrap, and for 2015+ the spot is for the DuoTrap S model.


IMHO the video is misleading. My DuoTrap S cadence and wheel magnets are installed without any modifications and work just fine. If it'd be useful, I can try to grab a couple pictures in the next couple of days. (FWIW I have a 2016 DS 8.6 but there's no apparent differences from the 2015 but for paint color)

As to value - if ONLY looking for a little trip computer then there are much cheaper options than what I suggested, such as the one steve_cay mentions.


I knew I wanted speed/cadence info to go to a small trip computer, plus my Garmin watch that I have today, and maybe to a phone app or a Garmin Edge in the future. In looking at the Garmin, CatEye, and Wahoo ANT+ / BT options I'd already be spending $60-70 just for the sensors. So at $75 on sale, the DuoTrapS/Trip300 combo kit was an easy choice for me. Even at $100 it's not bad if one expects to layer up in the future -- but not the best choice if you're not looking to use additional/alternate receivers later.
