    Look up The hub doctor on ebay I bet he will have a prepackaged set.

    I'll tell you what size bearings go in a 907 hub...

    Unlace the 907 hub and lace in a Hope.

    Unless you are just practicing wheel building for when you lace a real hub to that wheel, not sure why you'd choose a Hope, unless you just like wheel building and can't wait to do it again.

    I know people keep bashin' Hope hubs but I replaced my 907 with a Fatsno and it's been fine.

    Hope's fat hub failure rate is only second to Specialized. Much like Specialized hubs, you'll meet some people who have had good luck with them, but overall, they have proved themselves to be very unreliable. At this point, it isn't even debatable anymore.

    What's the problem with hope hubs? Is it bearing quality?

    I couldn't tell you. I know to run an XT cassette on mine and I clean and lube the driver a couple times a year and it works.
    My 190 one has been fine and I have 135mm hubs on a couple other bikes with zero problems.

    I actually just bought a 130mm Chosen hub (same as 907) for my Dahon folding bike with 20" wheels because I can't imagine I could harm it.

    Users of 170 and 190mm Hope hubs have experienced a higher than average failure rated when compared to hope 135mm hubs, based on internet feedback.

    Shall I relate how I ripped the axle and spider clear off of a Hope hub one time?

    Clydesdale + 29er + granny gear + steep incline = BOOOM

    This, and the 135mm is more durable than the fat sizes?

    Go DT Swiss. Trust me on this - I've hauled my Salsa Vaya up 6k feet in one day with 280 pound me and 45 pounds on the bike. It can handle torque far better than Hope.

    I used to have access to hubs to check things like that. Store closed up and moved to Idaho.
    It honestly takes about a minute to take the end caps off a 907 hub and see what size the bearings are.
