Brake upgrade ADVICE
So I got this 2011 Trek Marlin 29r for my graduation gift, entry level I know. I went out yesterday for the first time and the current brakes suck! ( BRAKE DISC TEKTRO NOVELA FRONT/REAR 160MM) A friend recommended Avid Juicy 7's, another guy recommended a brand called Hope. If I go with the Juicy's do I need a special kind or any juicy 7 will do the job? I am slowly going to upgrade this bike, I know it's prolly cheaper to get a new bike but this is my 4th 29r and this is a graduation gift so holds sentimental purpose plus the frame is solid. So any advice on a brake setup that won't break the bank would be awesome.
Also forks, the Suntour fork has to go, whats a good step up? Reba? Thanks guys
