When I started riding last summer I picked up Schwinn Circuit 24 speed. Eventually I will pick up a better bike, but this frame is good enough for now and I really can't justify the expense of a new bike at the moment. I know that can't make a silk purse out of a sows ear, but there are some improvements that I'd like to make. Primarily, the rear derailleur is a Shimano RD2200 and has been getting a little sloppy. I keep it adjusted and it shifts decently but I would like to pick up a different derailleur and swap it out with something a little better.
I have a triple in the front so I know that I need a long cage.
I also know that the width of chains for 9 and 10 sprocket cassettes are narrower than what I have with the 8 sprocket that is currently on my bike but I don't know if that will present any problems.
Any recommendations or suggestions?
