    Has Anyone Adapted a 135 Rear Disc Hub to Work with Front Disc Spacing?

    I've been searching around and have yet to find an answer. The rear hub is spaced 5mm inward. Has anyone adapted one to make it space to use with a 135 front fork?

    It's been done, some folks are even selling 5mm spacer kits to get the rotor over.

    Fatty In Hamilton - get yourself the Shimano Centerlock adapter, and then go from there with a new six bolt rotor and spacers... a Frankenstein setup. Makes your old rotor useless, sure, but you at least get to keep the hub.

    Avoid the Problem Solvers adapter. It doesn't spin true.

    With the 5MM bolts what rotor bolts are you using? With stock rotor bolts you only get like 3 threads of engagement into the hub? It just seems like you would need longer rotor bolts - which qbp doesnt seem to offer.

    That's true... sorry, forgot that part. I'll look through my order history for some bolts I used on my setup, back in a bit.

    Well, crud. I ordered a 3mm spacer kit by Magura that had some extra long torx bolts. Seems to be out of stock now.

    Maybe I'm missing something as I've never tried this but why not just space the caliper over rather than the rotor. Throw a washer or two between the tabs and the adapter. Longer bolts for that portion can be picked up at any hardware store if needed.

    You all seem to be missing the fact that rear hubs have 10mm axles and front hubs have 9mm axles.
    I got a surly rear hub to work in a jones fatfork by turning the 10mm axle down to 9mm on the ends then using a hope disc spacer to bring the rotor further out on the hub.

    That would work for IS mounted calipers, but not post mount. Can't move the caliper over that easily with post mount, unfortunately.

    if you need to move the caliper over 5mm, you can use a qr20 brake adapter.

    A lot of dropouts (mostly forged ones) are not made to tight enough spec that it matters. Also, the dropout can be filed out slightly instead of turning the axle down (if a lathe is not available).

    White Bros. is making an adapter that will move post mounts over. I think I heard that it will be requiring a 185 rotor to work, though.

    The disc spacers from Fatbikes.com were not enough to center the rotor in the caliper. I ended up spacing the caliper adaptor as well, using a couple of washers...It is now lined up perfectly...My set up is...Surly front hub with avid rotors spaced 5mm using the fatbikes.com spacers, Black Sheep front disc spaced fork with a Magura Louise caliper on an avid front adaptor spaced in with 2 washers...Bam Done works perfectly

    I like have the fork break spaced for a rear. Otherwise not much point of having a Ssp wheel on the front of my Pug.

    Or as i did with my Jones Truss fork i ground the drop out which is 9mm to 10mm then used a Carver 5mm disc spacer which comes with longer disc bolts for $20. job done

    So, there is normal 135mm forks for standard rear hubs.
    And there is some forks in style "use only our brand hubs".
