    Moonlander bb bearings

    after just 115 miles mine are gone

    Local shop has phoned ID distribution and they are scratching there heads of what to replace it with, so waiting on a phone call back while the bike is in dry dock.

    I think someone's moony packed in at 400 miles but 100 is a tad bad....and I have not been abusing it by any means, the pugsley has almost 600 mile from same terrain and it's running sweet.

    I hadn't thought about that aspect. Be a bit like the early days of fatbikes - scarce parts.

    They use same size as Shimano Hollowtec 2 so can use them, or Hope or Superstar etc...
    I will swap over a Hope BB that is on the 29er soon probably,

    If you fit a Superstar BB which does not have pressed in Bearings then you can buy loads of replacements cheap and fit quickly when needed
    Superstar Components - High Spec Parts For Peanuts


    You will need tools to change the Hope BB bearings yourself

    King stuff is awesome.

    Hoping the hope lasts!

    Only options at shop for bb cups were shimano ones at £15 or £30, or just go straight to a decent hope one for £65....I don't mind paying extra for something that lasts, though saying that, I can't seen the moonlander beach riding anytime soon.

    Its back in Newcastle so I will be limiting the miles.

    these king bottom brackets, do they work with a surly spindle? and you can keep feeding it grease, pushing out any impurities without taking it apart?

    Saltyman, it was my moonie that killed a BB in under 400kms.

    I had a no name ebay ceramic BB floating around but the shell housing was the wrong size (it was about 4mm wider for some reason). So I used it as a donor, punched the bearings out and put them into the Surly BB shell.

    Have done many more salt riddled k's on it now and the BB is perfectly happy. I think the factory Surly bearings don't have enough grease?

    Good question !
    An Ti ISIS spindle that will fit CK BB's is what i would like to have myself.
    (since a have a brandnew CK BB laying around doing nothing.)

    yeah, thought i saw your thread from a couple of month ago.

    i didnt notice mine at first, i usually just roll the bike out, ride it, wash it, then repeat.....until my friend viewed it yesterday and picked up on it straight away.

    at first we thought the bb was just tight.....it couldnt possibly be seizing at 100 miles.....but today it was confirmed when it was took apart

    i remember the pic you stuck up with bone dry rusty bearings......atleast yours lasted twice the distance.

    let this be a warning for moonlander owners, and i hope surly take note.

    Ah, external bearings. Not such a problem then, just a nuisance.

    I think they will just be the same as the external race face cups I rebuild last week. I have the bearing number for these in the man cave. I will get it to you the morn.
    Just measure the I/D & O/D & depth of the bearing & get a couple of sets ordered, cheap as chips.
    Remember to pop the seals & pack the new ones with quality grease before fitting

    im glad the local shop had a new bearings in stock.....i only popped in for advice......seems strange how a couple of moonlanders have had this issue early on though, the bike isnt even run in yet, if of thought the pugsley would be due bearings first having covered about 5 times more miles!

    Was this due to you not installing the Mr Whirly A1 washer?

    Look at the "Spacer Configuration Table" in the link above. You are supposed to have the A1 washer installed. You can not set the bearings correctly without it. The A1 washer is missing on all complete Moonlanders.

    i did mention it to the guy at the shop today, he then showed me the new hope bb and that has 2 a1 type washers, they were identical infact, one for each side of the cups.

    Whoever put the bikes together for Surly f***ed up! They obviously knew it because they included it in a little baggie with the bike. I would have been nice to include some instructions so this wouldn't happen!

    That's another thing i have been wondering....
    Why don't they just put stainless steel bolts on these bikes from the factory ?
    They know these bikes are going to see a lot of wet conditions.

    i removed every bolt that touched the frame and applied copper anti seize before putting them back in, just to save hassle in the long term.

    never used it on any of my bikes, all my bikes get washed, aired off them lubed after each ride, unless its just a local dry ride that is.

    to be honest i never keep a bike long enough....though i guess the moonlander will be long term.

    I've been told it does fit the Surly stuff. I'll find out soon and post results.

    And yes... I grease it with the grease adapter and a grease gun. One of them has been on my Stumpjumper since CK started making them. WAY longer than ant Shimano bb.

    nevermind, I thought my bb bearings were shot. I took everything apart, cleaned and lubed everything up and I am good to go...

    I had one tighten up and when I removed the bearing from the shell and pulled the seal, it was bone dry, just a smattering of grease. The other side that hadn't yet failed was bone dry too. I packed them up with grease and I'm still using them.

    Here's a sticky from the drivetrain forum on greasing the bb bearings:
    http://forums.mtbr.com/drivetrain-sh...cs-497220.html

    I did order a set of replacement bearings with tophat shield, only $12:

    Yeah I'm not surprised they were bone dry, seems they came from he factory that way....

    My hope BB is like new after almost 1,000 trouble free miles.

    Mine went bad around 400 miles or so. Upgraded to ultegra and no problems since.

    I'm a cheap basturd that doesn't want to spend $100 on a new bb for my new bike, esp since no bike company actually makes bearing (they all buy them from one of the same 4-5 suppliers worldwide). I emailed the Surly info email address a copy of my receipt and asked for new bb cups. A nice chap replied he'd be happy to send some out. Received them a few days later, the grease is oozing out of the seals, it appears the root cause has been addressed. I just installed them, I'll report back if they fail.

    necro also????

    so pardon my ignorance here if this is wrong, but would this problem be affecting the necro as well since it has mwods?

    should this thread be labeled mwod problems instead of moonlander?

    thinking of getting a necro, thats why i ask. thanks

    I decided to change the drive sprocket on mine right after I received my ML.
    There was no lube at all from the factory.
    I never would have known until it failed (most likely it would have failed up north on some remote trail in the middle of nowhere)

    Strange as it seems, but evidence suggests just the moonlanders were dying early

    Most seem to upgrade or repack with grease from day 1

    I read this thread a while back and checked my necro BB. It didn't have hardly any grease in it. I greased it up, but my BB is not very smooth after about 300mi. I'm am going to go ahead a replace it. I can't stand a tight BB. I think necro owners might want to check their BB's too.

    The only way to know for sure is to take the seal off and check them. Chuck some lube in and the problem is solved

    Looks like Surly fixed the bb bearings (from Moloko Bar | Parts | Surly Bikes
    The bearings on which they spin are also worth mentioning: we’ve upgraded our bearings on these and our Mr. Whirly and MWOD cranksets to aftermarket Enduro bearings with double labyrinth seals, meaning they actively shed and stay clean of dust, muck, and grime, even in wet and muddy climates. All O.D. cranks are available in black.
