Pros: - very durable
- long cage so it can shift 3 gears in one hit
- accurate quick shifting
- needs very little adjustment and maintanance
Cons: Havent found any as of yet
Recommendation: I have had this derailuer on my Giant Anthem for 4 years now and it still performes beautifully and perfect. It shifts on a dime with just a small click on the shifters. I love this derailuer.
Pros: Sleek profile. Great shifting. Good looking and sturdy. Shifts MUCH better than the earlier models and the reduced profile actually does help avoid "trail trash".
Cons: Really only have two small issues with this derailleur.
1. The bolts holding the jockey wheels are made of soft metal that is easily stripped out. Be careful when servicing.
2. Wish the unit came with the usual cable tension devise to help pull cable slack at the unit. Instead you have to use the ones on your shifters.
Recommendation: A sturdy and smooth derailleur that will have you forgetting about maintenance and enjoying the ride.
