How are you finding the bar end shifters? I've always wondered what it might be like to use those.
Bar end shifters on a TT bike aren't quite like having them on a road bike. On a TT bike they are mounted on the ends of the TT bars so that you aren't having to move from the aero position to shift. On a road bike they are on the ends of the drops.
