I have a set of these brakes on my GT LTS-3 and they are fantastic. I have ridden at several downhill parks with these brakes and I have never had to worry about my brakes not stopping me. I have used these in the rain/mud and it did not affect their performance. In my opinion these brakes are unbeatable for cable disc brakes.
These little tube shields do a great job of protecting your brake and shifting cables as well as your frame. The only problem is that they tend to work their way up the cable so they have to be check occasionally.
These tire levers work great, however, they tend to bend and break after multiple uses if you have stubborn tires. On the bright side, they are a lot safer for your rims, tubes and tires than a screwdriver is.
