The Good: Power, reliability, performance
The Bad: None worth mentioning
Been using this brakes for Downhill for almost 2 years now and I don't think I ever bled them.
My setup is 203mm on the front and 180mm on the back and they really have an amazing modulation and stopping power. Of course they are not as powerful as the Codes, but I even ran an 180mm rotor on the back and don't lack power with the Elixir.
On the adjustability side you only get the lever reach adjust, but for me it has been enough and don't really miss any other adjusting option offered in higher models.
Weight wise they are also very good, and also have the carbon lever option wich is the one I use.
Overall conclusion is that they are not expensive and will worth the money, as they will perform great in all conditions and hold up very well, even with little to no maintenance.
