    Hadley Bearings

    I have heard some people mention that Enduro Zero bearings are a much better quality bearing than those that come stock on the Hadley Hubs. What is the life expectancy on these bearings and what makes them so much better?

    No real difference, besides your wallet getting lighter buying Enduro bearings.

    Hadley uses external seals, thus the seals that Enduro claims to be superior, has no impact, even if they were so fantastic.

    Buy good quality industrial bearings, from brands like INA, SKF, F-A-G, NSK, Nachi, and the like.

    The original bearings in my Hadley hubs were Enduro bearings with seals on both sides. I was surprised as I thought there would only be a seal on one side. After a crazy wet ride, they were a bit crunchy. I looked for a set of replacement bearings and thought about picking up the Zero ceramic bearings. I called Hadley and asked about them and they recommended sticking with the regular bearings. Seems their experience with them was not-so-great. Folks were having more problems with ceramics then regular bearings, likely due to lack of maintenance. Therefore, I stuck with the regular bearings (Enduro bearings) and ordered a set through Hadley.

    How long had you had the bearings before you had to replace them? Also, how long have you been using your current set? I am a bit weary to purchase the Hadley hub because I don't feel like they should be effected by weather so easily.

    The sealing on Hadley hubs, is based on real industrial seals. Those seals will last pretty much forever for a bike hub, if maintained just reasonably.

    So what wheatgerm just told you, is that he didn't maintain his hubs, blew a seal, and got dirt inside the hub shell, past the outer seal and the bearing shield.

    That has nothing to do with the hubs, but a lot to do with a failed maintenance schedule.

    Most other hubs rely on the seals of the bearings, Hadley hubs has an additional seal, that is an order of magnitude more effective than the bearing seals.

    I'm in no way trying to sway you towards buying Hadley or any other brand for that kind of matter here, but simply making sure that wrong information is not left unchallenged.

    Could you explain how lack of maintenance would blow the seals. I don't understand completely. What would need to be done to prevent the seal from blowing?

    Cleaning and lubrication.

    If a seal is kept clean and lubricated, it will last for years.

    If dry and/or dirty, it will go south pretty quick.

    Where did I say I don't maintain my hubs? No, I do maintain my hubs and the seal was not blown. Problem was a 5+ hour CRAZY wet ride plus 3 hour ride back home with bike on hitch rack in driving rain. Tons of rain that day. Other bikes also had issues. Freak conditions. The lack of maintenance part of my post was based on the conversation with Hadley w.r.t the performance of ceramic bearings.

    I ordered the replacement bearings prior to inspecting them, figuring they were toast. I was leaving for vacation soon and wanted to have the bearings in hand just in case. They actually weren't. I replaced them then clean and regreased the old ones, which are now spares. The bearings were cheap so no big deal.

    That was over 2 years ago. They've been butter smooth since. They were butter smooth before that as well (over a year). I crack the hubs open a few times per year and regrease and relube everything. The internals are always quite clean. Only after the monsoon ride were things a mess. Other "normal" wet rides have been fine.

    Didn't mean to imply that the bearings and hubs are junk. Just some background on why I called Hadley and their thoughts on the ceramics. Save your money and stick with the regular bearings.

    I have asked a lot of questions because until recently, I knew nothing about hubs and this will be the most I've spent on hubs. All of my questions have been answered for the most part. I have never had a problem with seals on my cheaper hubs but then again I don't do an excessive amount of riding in the rain. My guess is riding for excessive amounts of time on any hubs in wet conditions will produce similar results.

    I understood what your were implying, I just wanted to get a different perspective. The Hadley Hubs seem like a quality product. What POE do you have? It sounds like you are into racing. I'm not into racing but more of an XC trail rider. Did you purchase tools from Hadley or do you just improvise when you take the hub apart to service it?

    I improvised but eventually got a pair of pin pliers from Repco . Bearing change is easy, as is servicing.

    My hubs are 72 POE. I don't race but like quality components. The Hadleys are keepers. Like Dan said, they spin forever. The roll faster than the Hope hubs I had before (sold with another bike).

    I purchased the pin cone wrench and 4-pin wrench only. I have since started using a Park 21-mm wrench because it is thinner and will clear the disk rotor bolts, which the Hadley tool will not. I am also using the Park tool pin spanner for the preload caps, which I adjusted once. Get the 4-pin tool and the Park pin spanner and 21 mm cone wrench. That's all I have needed.

    You may want to consider the rear bolt on axle kit as well if you're running a quick release rear. Nice upgrade.

    I am going with the 135mm x 10mm Ti bolt hub.

    Make sure if you can hear the freehub when you coast on your bike, that you open things up and put some more PTFE lube in the freewheel so that it is quiet again. If it is making a lot of noise, it's dry, and needs to be lubed. The pawls need to run in a bath of oil at all times.

    You should have a very hard time listening to the freehub when coasting, if you can hear it, it's dry, and dry is bad and doing damage to the freewheel. Hadleys need regular maintenance. They are a great high quality racing hub. Racing hubs need regular and frequent maintenance.

    That's my cue to service the hub as well. Only takes a few minutes to do.

    A seal that is not damaged, dry, or full of dirt (does not happen in one ride), will not let dirt through, unless you exceed their pressure differential limit. To do so, we are talking pressure washer or the like.

    As often as needed. This depends largely on your riding conditions.

    This summer has been extremely wet here in DK, so they have gotten a "clean & lube" ceremony like once a month.

    Help please,

    I am in Australia so Hadley parts are a bit thin on the ground, I have pulled apart my rear hub and it was full of crap, my bad, Fatbike ridden on Beach, down beach in water etc... anyhow.. sourced main bearings, cleaned everything up but the bearing in the freewheel was smashed, not the needles, cleaned them up okayish, but the sealed bearing, does anyone know what it is? Size/number???

    Would happily buy the kit if anyone knows where they are available in stock.

    Have tried to search it no avail, is this address current suzanne@hadleyracing.com it was the only one I found and no reply as yet.

    Appreciated, dave.

    There is a number on the seal of the bearing.

    If you give me that number, I will translate that into the industrial standard for you.

    Looked everywhere for the seals, the bearing either did not have seals or I have just lost them. I found all the seals for the main bearings and none have numbers on them, the bearing itself has a serial and that is how I ordered them here from the bearing shop.

    I will take the broken bearing in and see if they can measure it and match but if I had a reference it would be easier.

    Thanks for the reply BTW, Mr Magura.

    Just measure inner diameter, outer diameter, and the width.

    Okay, after a major battle verniers....
    OD 1.161" or 29.5mm
    ID 0.79" or 20mm
    Width 0.32" or 8.12mm

    or something, geez, it's just a bike, is it meant to be this hard?

    Okay so I just punched "bearing 29.5x20x8" into search and I came up with
    I was told by hadley that the bearing in the freehub is a custom size. You are essentially forced into buying a rebuild kit. (pawls, bearings, etc.)
    Which I am still happy to buy, but hey, can't find that either.

    Glad I am not in the middle of the desert with a busted freehub...

    Is there no print on the bearing of any kind? Manufacturer or the like would help a lot.

    Thanks, saw that kit, out of stock. Would like to do the 12hr in three weeks, insert sad face.

    I have emailed Greg at Speedway AK, that's where I got the hub, he does a lot with Hadley, hoping he can help me out. Also sent an email to Balle racing to see when and if...

    I will have to hang my head in shame, and admit that I can't seem to find that particular bearing anywhere else

    If you give Hadley a call, they usually sort things out, so however stupid it feels to write this, that's my best suggestion at this point.

    I have a bunch of Hadley hubs myself, but have never had a dead freehub bearing.
    Fact is though, that if it ever happens, I will replace it with a polymer bearing.

    Try learning from facts, rather than getting butthurt.

    This is engineering. If you wanna dispute engineering, better carry yourself like an engineer.

    We are not discussing who fells what is right, but simple, basic engineering.

    Now if you feel like claiming that seals don't work, by all means do so, but back up your claim.

    Haha the moment when people can't thicken their skin and listen to someone with engineering experience speak as they usually do: clean cut.

    Maintenance, with the proper grease for the conditions, should make it last.

    You got a point there worth emphasizing (man that word was hard to spell).

    Proper grease for the conditions. Often an overlooked detail, that makes quite a difference.
    The standard "FinishLine white grease rocks" mantra, is not gonna cut it here.

    The easy solution is to have a chat with a local app. engineer from Shell or the like.
    They know the local conditions, and you will get a fairly priced industrial product.
    Draw a bike on the bottle if that's too boring

    Seals dont work when they're not installed, like hadley bearings..

    No external seal is going to seal everything out. You're getting a bit on a high horse considering you dont know how/where he rides Ive had my bikes submerged up to the bottom bracket more than a few times, theres no seal on a bike thats going to keep crap out under those conditions.

    Bearings fail and they're cheap. I have a drawer full of sealed bearings, I dont even bother to maintain them anymore.

    If they are well maintained, they sure do.

    I live in a place, that offers rain like 200 days a year. I never have those problems.

    My Hadley hubs are soon to be vintage pieces. They look like new inside.

    Really, as Ehigh pointed out, it's a matter of choosing the right grease for the purpose, and keeping things clean.
    A respectable industrial seal, is made for that purpose, and if it didn't work, loads of other applications, which for at least a part of them are more demanding than bike hubs, would fail left and right.

    What this discussion should be about, is maintenance and lubricant selection, instead of discussing if an old tried and tested solution works as intended

    Bearings fail. Its not that big of a deal, or a call to scold over maintenance. Toss new ones in, call it good. Your maintenance speech doesnt help much for bearings that are already damage.

    True, but it may very well keep a lot from being damaged, no?

    True, a damaged bearing is a damaged bearing and when it's done it's done. However, when routine maintenance is done properly, you'd be more than likely to catch that something is the matter upon examination before you have something significant occur. Bearing wear is progressive and hardly seems to happen all at once. The same can be said for seals. It wouldn't go from fine to wrecked in a ride. It seems like there would be some indicators prior. I know sh!t happens, but again-seals, I haven't ever had any that have gone to crap without some forewarning that was indicative to negligence. Neither have any of the ones I've seen.

    This is all based upon my experience. Maybe I've just found the right horse to stand on.

    The seals I've seen blown are usually because someone is trying to use too light of grease. On the flip side, I've known some cold weather riders to have problems with too thick of grease. It's all a lot of hokum though, I know.

    Reassembly process seems the easiest way to eff the main seal (how to hold pawls down)..

    By now I guess we can conclude, that we are just two old idiots, with no idea of what we talk about
    I'm quite comfortable with that, how about you?

    I'm going to attempt to service my front 20mm Thru-axle Hadley Hub. My hubs were serviced at the 3-4 month mark. At that time, the bearings were replaced (even though the mechanic said they were still good) to solve a grinding noise that started a couple of days after a rain ride. I am now at the 1 year mark, and I want to service the front hub. I think I should buy some bearings in case the current bearings are worn. I have some questions:

    1) How do you know if the bearings are worn?

    2) Where can I buy good, inexpensive(i.e. not ceramic) bearings in the US?

    3) I was going to use Slick Honey for the grease. I ride in dry, dusty, desert conditions. Is that grease suitable?

    Thanks.

    You should use a heavy wash-out resistant grease. Pretty much anything but slick honey. Regular old marine grease is excellent.

    Bearings usually show a ring on them of some sorts, but any imperfection that is visible is a tell tale sign.

    Compare prices, see what works.

    I wouldn't recommend slick honey. It might feel "really good" for half an afternoon in those conditions, but then it will feel like "something's not right here"
    Slick honey often does not belong in there. Maybe if you raced and someone broke it down for you daily, then yeah-it would be worth it.

    2 years of a beach, racing, mud and rain, touring with loaded panniers... thought they were feeling a bit rough, might have to rethink my service intervals

    Greg from Speedway has got a kit for me and is sending it now, Balle will have kits later next week according to Hadley.

    Thanks again.
    Don't grow up, it's a trap.

    A heavy grease? But Hadley's own grease is supposed to be a 'light' grease.
