I purchased this for my old school early 90's road/commuter bike. I am using it with a shimano mega range 7 speed freewheel, and it works great. Easy, and smooth shifting!

My rear derailleur bent from the crash. It still worked; but I finally stopped being cheap and replaced it with this new same model. Everything works great now. This cheap RD will serve you well if you know how to properly installed and tune it (like every other RD-cheap or expensive). With proper installation, it shifts very smoothly and has good snappy response. I recomment this.

After I went way to hard on my bike in the woods with my friend (being the test-monkey in up to 20" deep puddles), my rear derailleur broke, so my mom, the real user, bought me a new one. It shipped here in about 4 days. When I got home from school and found it sitting in the box, I was EXTREMELY excited. I went into the garage, placed the tools on the ground, and started fixing my Schwinn bike. I thought it was going to be hard, but it was a piece of cake. I didn't even need the instructions! Who says fixing these parts of a bike is impossible? It's indeed a good product and is easily put on. Luckily, it didn't need any assembly and came in 1 piece. Now, my rear derailleur might break again cause I ride the bike way to much!!!!! I ride the bike every day about a mile and listen to my Ipod the whole way. I'm so thankful my bike is fixed. This is a good product and if you have doubts about buying this, back-up and rethink your answer. GOOD PRODUCT!!!!!
