Easy to Install and Adjust

I purchased this new derailleur to replace an older version of an Altus derailleur that had been damaged during an accident on this 21 speed mountain bike a while ago. After bending the derailleur mounting lug on the bike's frame back into it's correct position, this derailleur fit and performed perfectly. This newer model appears to be better constructed and is lighter than the old one. Instead of a longer cage this derailleur has larger cogs that save some length. The cable connection works like a charm and after minor tension adjustment this derailleur operates smoothly and accurately.
