    Having the same problems with an older (24 POE) 170mm Fatsno hub. I've broken two aluminum freehub shells, exploded two inner freehub bearings, and replaced two main drive side bearings after they got very gritty. All have been stock hope bearings. I'm 300+ lbs.

    I had an older steel freehub from a past hope hub but the bearing ID is too small to fit on the Fatsno axle. I thought all hope freehubs were the same?

    There is some confusion on what bearing are required for the freehub. Is it just two 17287's or is it two 6803's and one 17287?

    No, the Fatsno hub and the Pro 2 EVO use a thicker axle, so the freehub body is different too. You need a freehub for a Pro 2 EVO hub

    Ugg, just stumbled upon this thread. Decided to check my rear hub, lo and behold the bearings are crunchy. Also the aluminum freehub body is all chewed up. Front bearings still feel good though. 3500 km.

    Bearings are pretty cheap, easy to get, and easy to replace. I repacked some after 2 seasons, put brand new ones in others (I have 4 hope hubs).

    Jayem....this is a interwebz forum.
    You should only post negative things. That's the rulez!
    But , yes....I agree with you.
    Oddly ( or not so oddly)....the Fatsno rear I have that is only used during winter is a little rough after 3 seasons. While the Fatsno rear that is used all year , for 3 years, with thousands of miles on it....is rolling smooth ( but is going to get new bearings for the reasons you stated)

    Crazy, I've had 4 sets (still have 3, sold one with old fatty), first one that is over 10 years old. All on original bearings.
    Had a couple pawl springs break on the oldest one but that's it.

    Went from fatsno to dt Swiss 350 & will never go back. Hope- broken bearings & cracked hub bodies, Hope should have had monthly direct withdrawal from bank account it was costing a lot.

    Well I only checked my bearings because I came upon this thread. A lot of people have had problems apparently. But thanks for the positive news. It seems like it's just the two 6903's that need replacing on mine. Just had to replace the bearings in my RaceFace BB30 last week, hence the disappointment. I'm about to embark on a 4000km fatbike tour so I need things to be reliable.

    I recently had a bearing failure in a Fatsno EVO 2 rear hub that had seen very little use. The issue was not that the bearing was poor quality, it's that the bearing recess in the hub shell on the drive side was too tight and compressed the bearing. This was quite evident when a new bearing was installed. When pressed onto the axle it was fine, but once it was pressed into the hub shell it would bind.

    I contacted Hope and they provided me with the dimensions for the hub shell and axle. I measured both and found that the axle was within spec, but the hub shell was undersize. Their recommendation was to remove and reinstall the bearing to loosen the fit. I ended up doing this on both the axle and the hub, using the original, damaged bearing. I got the axle to the point that the bearing could be seated with heavy hand pressure. Using Hope bearing seating tools, it took 8-10 cycles of seating and removal to loosen the fit of the hub shell sufficiently, but it did the trick. Hope sent me a new bearing "as a courtesy" and everything feels nice and smooth now. I don't anticipate any further bearing issues.

    Great tip bnystrom!

    The next time my bearing fail, I'm sure later this winter, I'll go through a session of removing and reinstalling the blown bearings before installing new ones (for the 4th time in 4 years)!

    After 2 years on the original bearings I have re-greased once but it's time for replacement as they are rough and starting to drag.

    I have just ordered SKF Bearings for the 6803 / 6903 and then the Enduro ABEC5 for the 17x28x7, as SKF don't make this. I will repack them all with my chosen Lith-Molly Grease before fitting and hope these give me another 2 years.
    Just quoting this, as I was going to suggest this.
    SKF probably makes the best stainless bearings on the planet, use their bearings on my snowmobiles as they last the longest, by far.

    Something to think about looking into if you continue to fry bearings at an alarming rate is the dimensional relationship between the axles shoulders and the bearing bore distances in the hubshell. In a hub like the hopes, having too much distance between the axle shoulders and where the bearings sit will overload the bearings when you tighten down your thru axle. Thus causing premature failure. Conversely, if the distance were too short, the hub would develop play as the bearings wore in.
