Crisp shifting. Many times i shift from the smallest ring to the biggest ring as fast as i can using SRAM x.7 triggers and i did not even experience any chain suck. The deraileur is so good better than what i have before which is a Shimano XT. All SRAM X.7 items are highly recommended!
I've been using this derailleur for 8 months now riding on every weekends, and theres nothing that i can think of that is bad about this product.
