Just last weekend I was on a long group ride (about 350 miles) when just 8 miles from home suddenly my bike started to wobble. I was going 65 mph so I slowed quickly to a stop and sure enough I had a complete flat in the rear tire. Long story short I put a plug and had to add some fix a flat to get me home.
I took the wheel off and saw it was easy to take the rear sprocket off. I did some research and decided to change it from a 41 tooth to a 39 tooth sprocket. I bought a new tire (Michelin Pilot Road 4 which could be a new thread) and just got it together. I took a short ride slowly to wear the new tire in so I can't be sure of the results yet.
My goal was to lower my rpms a little, especially at highway speeds. I estimate to lower 200 rpm at 60 mph. Has anyone done this change and what are the results?
