I am getting some chain rubbing in mylowest and higest gears. I asked about it at the bike shop and was told that is the way it is. Im new to road riding and not a mechanical minded person but I find it hard to believe modern bikes that are well maintained have chain rubbing which I must believe slows your speed and wears your parts faster. My bike is new, ultegra and FSA compact crank. Any feed back as to if this is truly the way it is or if you can point me in the right direction on how to resolve will be greatly appreaciated.
