The initial outlay does seem a lot but by my reckoning and having loads of bikes it works out cheaper, or maybe reasonable would be a better description. Swapping between bikes is very easy and mounting kits are cheap enough, remember there is no cables. The biggest boon though is being able to upload all your ride data, Garmin connect and strava are wonderful, and as mentioned really do help you get out the door. G think of it as a dropper type accessory, costly but worth it.
