Looking for advice on mounting hardware to mount Sram XX disc brake calipers on my Cannondale F29 Carbon Team. I posted pictures below. The only hardware I have are the Torx screws that came with the calipers. The front is a Sram XX hydraulic disc caliper with a 160mm rotor and Cannondale Lefty 29er 100mm fork. Looking for advice/recommendations on the best spacers and bracket options to properly mount the caliper. For the rear it is a Sram XX hydraulic disc caliper and 160mm rotor. Some people have suggested going to a 140mm rotor which seems really small to me. Similar to the front - looking for bracket/spacer recommendations to make the setup work. Please see attached pictures of brakes and frame/fork mounting. Thanks in advance for the help.

    Photo gallery may be of use, you haven't labelled your photos incorrectly have you.? The rear looks like it is a direct mount to frame using torx bolts.

    If I am right then front would need an is to post mount adapter.Just checked and that is definitely the case.
    The rear may need a post mount adapter depending on rotor size. Avid need a series of flat and domed washers on mounting bolts in order to align the pads to rotor.
    Obtaining correct adapter is a case of measuring the gap between the fork or rear dropout monting points.then specifying the rotor size you are using for examle to run a bigger front youneed this ......http://www.cannondaleexperts.com/Avid-D ... _1469.html

    The CPS washers aren't used on that model brake.

    The adapters needed are the Avid '0mm IS' adapter on the front & the Avid '20mm Post' adapter on the rear.

    Thank you for the reply and the attention to detail. It took a little work searching for the parts but I was able to find them online. Ride well.
