    MX-4s not cutting it

    I am currently running Hays mx-4s on 6 rotors and needless to say they are not stopping my 236lb frame the way I want them to. What do I do? I am on a budget but I want better brakes. Should I try a bigger rotor on the front end (cheapest fix) or just toss the brakes and buy some hydraulic ones with bigger rotors?

    8" rotors should do the trick. Maybe 8 front, 7 rear. That'd be the cheapest fix. MX-4s do suck though...

    you need 8 inch rotors. if you had something like 6 inch saints or codes, you'd still probably be having problems!

    if you dont mind spending more, you'd enjoy the step up to hydros though! hayes9's are only 65 bucks for 8 inches right now.

    Is it okay to put an 8" rotor on my XC bike? all the manuals say nothing bigger than a 7".

    What is the differance? http://www.jensonusa.com/store/produ...Packaging.aspx

    if your fork says 7 inch max, dont go bigger! max front rotor will be determined by the fork only.

    i run an 8 inch rotor on my xc bike.. but its rated for it.

    Looks like one is in plain packaging possibly returned or take-off. If you can afford go for the HFX-Mag or better yet the Stroker Trail.

    Would you rather spend hours searching for the best price or go to a place that does it for you. Think with the big head.
