I have a Sora 3500 set on my bike except for the shifters, which are Alivio ST-M310 and a 22.2mm flat bar. Now I have a new bullhorn which I would like to install, but the old shifters don't fit, because the diameter of the bullhorn is 23.8mm.
I would like to have the brake and the shifter at the end of the bar, somting like this image. I thought that a bar-end indexed shifter and TT brake lever would fit quite well. I have a 2x8 gear system so, I think a Shimano Ultegra 6480 Triple 8sp Bar End Shifter would be perfect.
But I can't find a TT lever-like brake that has a mounting ring rather than plugging in to the end of the bar.
Is there a brake lever (for caliper brakes) I could look for so that both (brake & shifter) can be mounted at the bar-end?
Where can I found a reverse brake lever with clamp mount, and not internal handlebar wedge-sleeve mount?
I think, I found the answer, but can you correct me if I'm wrong?
