Hello.

I have just started to get into road cycling, nothing to serious, just cycling to school and the occasional ride. I want to upgrade to sti/ergo levers on my bike but dont wont to fork out £80 for shimano soras because i think its way to expensive. On ebay ive noticed that you can pick up cheapish campagnolo ergo shifters but ive read that these are not compatible with shimano rear derailleurs. Is this true? In particular i want to know will a campagnolo avanti lever be compatible with a sora mech.

Thank you.
