Shimano F203P/P Disc Brake Adapter

Shimano F203P/P Disc Brake Adaptor

Shimano Disc Brake Adaptors are the finest disc brake adaptors available for Shimano disc brakes. Utilizing an extremely stiff aluminum construction, you will achieve your proper brake alignment and optimum function. This adaptor is for mounting a standard Post Mount caliper to a Post Mount fork to use a 203mm disc brake rotor. Use only Shimano brake components for the best braking performance.

Please note: this adaptor is designed for the 160mm native post mount standard. Some newer forks are 180mm native and require a different adaptor for mounting. Please check your fork before ordering.

    Pike Fork - 160mm post to 203mm Adapter
    This would be a 5 star review, and in truth, for the price it could still be... but... The package comes with 2 mounting screws. If you currently have a 180mm adaptor you have long screws. The way this adapter works is you screw it into the post mount, then screw the caliper into it, you need.... 4x short screws. So, if your moving from 160mm to here, you'll be fine, if your moving from 180mm to hear you must obtain 2 extra short screws.

    Required to run a Shimano 203mm rotor on a RS Pike or Lyrik
    I strongly suggest running the larger rotors on Enduro type bikes and this adapter allows you to run the 203mm Ice Tech rotor on a Pike or Lyrik which has a post mount for only 160mm rotors (which is baffling as they should be for 180's at least!).

    When I was upgrading to a larger Rotor the jenson service tech was able to direct me with the correct adapter can't think over the phone service to be well turned out as it did.

    Will this fit a manitou magnum comp fork?
    A shopper on Dec 27, 2016
    BEST ANSWER: Yes, all of the newer suspension forks are post mount and accept the standard brake options. That bracket just raises the caliper to accept the larger rotor.
    Does this adapter come with hardware to fasten it to the fork? Also is hardware supplied for the caliper mounting?
    Ian P on May 16, 2017
    BEST ANSWER: This adaptor includes bolts to mount the adaptor to the fork, but does not includes hardware to mount the caliper to the adaptor. The brake should include brake mounting hardware.
    I am looking to change my rear brake on my dirt jumper from a 140mm disc to 180mm. Is this what I need to do that.
    Kellen on Apr 15, 2016
    BEST ANSWER: No, this one is ofr a fork only, you will need the shimano r180 rear adapter
