Assuming you’re not using your water bottle caddy for H2O, the boomBOTTLE will add a complete wireless sound system to your bike. Pairs with Bluetooth phones and works as a speakerphone.
It has 6 extra buttons, 2 at the shoulders and 2 switches at the back. Map commands from the face buttons to the extra ones and you never have to take your hands off the analog sticks.
