Regarding the brakes, yes I’m flipping the lever to open them up. I guess it ultimately comes down to whether or not I want to spring for new tires along with new wheels, plus going down in tire width. The Roubaix Pro 25/28’s are almost new and they REALLY improved the ride from the stock 23’s that came with the bike. The only wheelset that I’ve been looking at that would still allow me to run the Roubaix’s is the Shimano WH-RS500 “Ultegra” at 15mm internal. I’m glad I asked here before rushing out and buying something that ultimately might not fit.
