Your LBS should be able to tell you if aero bars will fit on your bike. However, I'd like to go off topic for a moment.

Aero bars are designed for a specific purpose on road bikes and are used for time trials. The rider fit is important for their intended use. I would suggest you try to find someone with an ordinary bike with aero bars fitted and give it a go. You will find that the bars are an acquired taste and do take some getting used to. Invariably, you will take them off your bike and sell them to someone else who will eventually take them off their bike.

Alternate choices that in my opinion make more sense - bar ends, compact drop bars or any of the other tried and true touring bar configurations that will be available for your bike. The last thing any bike slated to carry a load needs is something that will make the bike twitchy to ride.

My opinion. Good luck. Al
