I purchased the derailleurs for my mountain bike from a Sports & Outdoors store and I'm very impressed with their performance. Through trial and error, I found that these derailleurs provide a smooth shifting experience even on the toughest of trails. The crisp shifting with great precision allows me to easily navigate through any uphill and downhill trail. The weather-resistant aspect was just icing on the cake. The only con is, it may take some time to properly set the derailleur gears up, but once set......it's a smooth ride!!
