    Fuel ex8 29er brake rotor sizes

    I have a 14 ex8 29er and was wondering if anyone had any concerns about running a larger diameter rotor in the rear of the bike. I am not lightweight necessarily, at 230 or so with gear, and I like the extra braking power the larger rotor offers. I am simply concerned that the extra rotor torque may cause damage to the post mounts and or impact the abp in an undesirable manner. Any opinions on this? I'd like to match the front with a 180. I haven't tried it yet, but had 185s on my hardtail and liked how linear and powerful they were.

    You can run both 180mm front and back with no issues. My Fuel ex 9 29 came stock with that. You will need an adapter for the bigger rotor though.

    Awesome. Thanks for the info!
    I have the adapters and rotor and all lying around just wanted to know before I went on with it.
