Lights and GoPros and bells, oh my!
These days with GPS units and dropper post remotes, etc. there's no shortage of components and accessories that need to fit on your handle bar. The i-Spec brackets allow you to get rid of your shifter clamps and mount your shifters directly to your (Shimano) brake levers. This frees up valuable handlebar space for that floating eyeball bell you've been... uh, eyeballing.
It's a great way to help unclutter a cluttered up bar.
