    Where can I find a front hub with rear disc spacing?

    I have an On One fatty carbon fork and I want to build a new wheel.

    I have the same fork and went with one of these...

    9:ZERO:7 Rear Spaced Front Hub offered by Fatbikes.com

    Great hub. Reasonably light. Smooth bearings. Only issue is that shipping was high from Alaska.

    Agree on the Surly. I went for the 135 mm ultra new rear disc. It's 135 mm spaced, rear disc, and it can accommodate a fixed gear or a free wheel if you ever want to run it as a rear.

    I just picked up the 9Zero7 hub. Cannot beat just over $50 shipped. And in all fairness the high shipping cost is 2nd Day FedEx.

    Hope, 9:Zero:7, to name a couple. Front spaced, use 5mm spacers or a wheels mfg. spacer ring. That's a benefit to front spacing is with or without spacers it's universal.

    Actually it is the other way around. Rear spaced hubs are universal. They can be used on front or rear spaced forks. Use 5mm spacers on rear spaced hubs and they can be used with front spaced forks.

    There is no way to use a front spaced hub on a rear spaced fork, they can only be used on front spaced forks.

    The 907 hub is great. I've had one on my bike for two years.

    Now... When I built my son's 907, I used a 135mm Bike Hub Store hub. I was under the impression it was rear spaced. I didn't check it before I laced the wheel. Built the wheel, went to put it on the bike, brake rotor was too far inboard to go into the caliper.
    I took the caliper adapter and filed it where it bolts to the fork. Got it to work. This was going to be a temporary solution until I could re lace the wheel but it's given us zero problems so I'll leave it until he out grows this frame and moves up to another, probably with 150mm spacing.

    What you mean is the rotor was too far OUTBOARD since it is front spacing. If it was too far inboard it would be rear spacing.

    Just FYI they actually manufacture an brake adapter similar to what you hacked up to convert front to rear spacing provided you upsize rotor to at least 180.

    I stand corrected. I had to go look at the bike to be sure. Yes... I saw that adapter but no one was going to have that thing in stock and we were excited to go riding that day. I had just been given the ok to get back on my bike after a broken ankle.
    I filed a 180mm adapter so we could have just bought the aftermarket one if we needed it.

    I just got one of these forks also and wound up going with I9 primarily because my rear hub is I9. 135mm, 10mm axle, QR, and rear spacing, no problem. They don't sell many but it was on the shelf and just waiting to be anodized whatever color the customer wanted. It was shipped 2 days after I called and at my door 2 days after that. Admittedly not the cheapest alternative though.
