    How to go from 6in rotor to an 8in?

    Sorry for the newB question but I just bought a bike that has Avid BB5 mechanical disc brakes and was wondering what all is involved in upgrading to an 8in (or so) rotor for more front braking leverage? Do I just need the bigger rotor and some type of special bracket to reposition the caliper?

    Thanks for the help guys and gals!

    Thanks guys! I emailed the help desk at jensen to make sure i get the correct parts to make this all happen. 6 inch rotors on 29in wheels is alright, but not remarkable... the extra leverage would be nice!

    Thanks again,
    Rick

    Make sure that your fork is cleared for the larger rotor.

    The BB5 is an okay brake, you'd get better feel and performance out of a BB7 or hydraulic.

    8 inch on the front is fine ... but not on the back as it is much easier to lock the rear ... at the most 7 inch but I am sure there are riders out there who uses 8 inches on the rear as well ... depending on what type of riding you do ...

    i went 8/7 (front/rear) on my FS and 7/6 on my HT ... works pretty well
