As I mentioned in my post above, I'm going from flats to drops on my Sirius X1 carbon. I love the frame. The geometry is very similar to my Caad12 and my RLT9...it kind of fits right in the middle of the two. Make sure you compare geometries of other bikes with your current bike, and take measurements so you are confident the handlebar change won't be uncomfortable for you. It will cost me $350 for some Rival 1 shifter/brakes. I already have bars and tape. I'll also do the work myself, so that will save $100 of shop labor. To me $350 is cheaper than a new bike, and I can keep the frame I like. Plus, I just like messing around with bikes...I may switch it back at some point! 😉
