The bike you see here is my road bike. I'm using this as the exaple because the levers on my Giant was changed to a lever that was no longer sold. But the one on the Bianchi; the lever extender is still available. So if you want the set up look up the site that I had posted earlier. Hope this help. As for the modification of the extender, well that is something I could show you how to do later if desired.

And my mtb.
