I run a pair of Avid Juicy Seven's on my Mongoose. The work great for XC riding and the modulation is superb. I only have a problem when I DH ride or FR aggressively. The fronts start to fade a bit. A couple of times I almost thought I was out of brake. Thats why I am looking to upgrade to 8" rotor on the front. Whats all the hype about the Codes? Are they any better than the Sevens with an 8" rotor?
