Yeah, I guess this works. I'm just not a fan of messing around with screws and components unnecessarily on my bicycle. If I would do this, I'd go through the front derailleur to not have to remote the seatpost. For now, I'm not updating them since I find it completely stupid to have to buy separate parts to update your bike (at least the accessories should be included when you buy the bike) and I hope they'll come up with a wireless fix soon.
