Here is a man who will tell it as it is and back up all his views with data and knowledge gained over a career within the aerospace industry. I have had the pleasure of viewing all of Hambini's videos and each one imparts knowledge which cuts through the never ending hype used within the cycling industry.

      Washing bikes, especially if you use degreaser is the number one way to kill your bearings prematurely. Bearing seals are very good at keeping water out, but add some surfactant such as soap/degreaser to it and the the surface tension drops right off, allowing it to wet into places normal rain/spray will never go. In the MTB world it's usually the cleanest bikes, especially full suspension ones, that have the worst bearing life. I read and article by a Santa Cruz mechanic a few years ago where they found bearing life on bikes with similar use was worst on the ones that are washed and polished the most often, with bikes that get no maintenance at all second and bikes that get the big dirt knocked off, but no degreasing/deep cleaning lasting the best. The folks who keep their bikes spotless (But ride in dirty conditions) spend too much time cleaning the bike in the first place and then have to spend even more time and money on maintenance they've caused by too much cleaning. The bike component companies love these people, I'll stick to dirty looking bikes that run for thousands of km between significant maintenance work instead.

      Yup. I watched his BB30 bearing replacement video, and then swapped out my own.
      With a cheap bearing press, it was much easier than I thought. One less job I need to pay a bike shop to do.
      Plus, buying bearings from an industrial supplier is way cheaper than ordering a "kit" from a dedicated bicycle supplier.
      That said, Hambini is selling Smalley snap rings for 4 quid, which seems to be the cheapest in the UK. Maybe I'll consider a kit after all.

  • @D.Eldon_
    @D.Eldon_ 5 ปีที่แล้ว +11

    *This was a great video. Thanks!!!* But it seemed like a mere introduction to a summary of a synopsis to the subject. ;-D It left so many questions hanging, like "Which of the two bearing types presented in the video is superior for the various applications in a bicycle (wheel hubs, BB, headset, jockey wheels, etc)? And there were so many characteristics and specifications of bearings that were not discussed. Please bring your Hambini engineer back for some followup videos. In addition to the above, here are some more questions that come to mind...
    _Question 1:_ Regarding the problem of mixing materials of different hardness in a bearing, some manufacturers like CeramicSpeed claim to treat the steel races in their bearings with some kind of coating that makes them harder or smoother so they wear better with the ceramic balls they use in their bearings. They often charge a premium price for this extra coating. How much can a coating really help? If coatings do provide significant help, how long do they last?
    _Question 2:_ Many properties of bearings were not discussed. For example, ball bearing quality is specified by roundness, smoothness, hardness and elasticity. It's commonly understood that ceramic ball bearings are usually much harder than steel. But what about the other properties? Is there a point at which a steel ball bearing is a better choice than ceramic because of these other properties?
    _Question 3:_ Some manufacturers like Shimano still make high-quality wheel hubs with cup and cone bearings. Why? What advantages do cup and cone bearings have in a wheel hub over cartridge bearings? Better lateral force handling? Would it be unwise to replace the steel ball bearings in a cup and cone hub bearing with ceramic ball bearings (since it's easier for ceramic balls to score the races if dirt gets in, thereby ruining the hubs)? Or would the benefits of ceramic ball bearings in a cup and cone hub bearing outweigh the disadvantages (assuming they're kept clean)?

    • @peglor
      @peglor 5 ปีที่แล้ว +4

      One of the reasons Shimano stay with cup and cone is because they do their own bearings and bearing seats (Cups and cones) AFAIK. If you manufacture in huge volume, it's possible to get similar performance at a lower price with cup and cone. Most hub manufacturers don't do enough volume for this, so by putting crappy unreliable bearings that spin smoothly enough to feel good in the shop and claiming their products are better because they have cartridge bearings, they can easily make a sale.
      Standard grooved cartridge bearings die very quickly if they have side loads or alignment issues because they're not engineered for them. At the high end, the likes of Hope and Chris King will engineer their own cartridge bearings and I suspect a lot of their work goes into making sure the bearings tolerate misalignment well. In fact Chris King hubs use angular contact bearings rather than grooved bearings AFAIK.
      Most off the shelf cartridge bearings (Especially in bike sizes) are built for machinery where loads are low and speeds are high rather than for bikes where car levels of torque are being applied, but at heading for 100 times lower rpm. Even a beautifully aligned hub/BB that's built to a competitive weight will flex enough under the pedalling/braking loads normal cyclists put through them. The genius of cup and cone bearings is that they realign themselves dynamically by running up and down the cones/cups as the bearing alignment changes, without self destructing. This can be seen by the way the wear line visible on the bearing cones when a cup and cone hub is dismantled is much wider than the contact patch of the bearing.
      The corollary to this however is that it's not cheap to make cup and cone bearings that are genuinely good. Basically in Shimano's MTB lineup, the only setup that lasts more than a couple of years (Or a little as a few months in the case of Deore hubs and below) without getting grindy is XTR, and it's all about the bearing material, surface finish and the hardening on the bearing races (Shimano's marketing blurb implies they're using a cubic boron nitride type coating on their cups and cones, but whatever they put on XTR it's literally 5+ times more durable than XT), combined with slightly better sealing.
      In fact anyone who wants their Shimano hubs to run better for longer could do a lot worse than spending the extra 2 or 3 Euro to get Durace/XTR bearings for their cheaper hub instead of just replacing with the same level of bearings the hub came with, or worse, a bag of random bike shop bearings the right size. The downside of cup and cone bearings is that when the cups are damaged the hub cannot be economically repaired, while you can keep feeding a cartridge bearing hub new bearings until the bearing seats are wallered out, which will take a while if good bearings and careful installation are used.

    I use an NLGI grade 2 full synthetic grease for my cup and cone hub. Its PTFE based instead of lithium, which is a soap base and does NOT play well w/ water. Its been put through its paces in all of my fishing reels (heavy salt-water use) and passed w/ flying colors. It doesn't emulsify in contact w/ salt water and stays right where you put it. It goes by the name of Super Lube :)

      @@thelawnet it may be but its the only place that it goes in the drive-train too. I ride/race a track bike on the south Texas coast so I'm always in contact w/ that salty sea breeze. Since repacking my hub when it rains got pretty old. i decided to use the lube that i use in my reels, which recieve heavy inshore/surf abuse, to keep me from repacking as often. Lol you may lose a fraction of a watt but hey, I aint complaining. Besides, my rear wheel is fixed and acts like a flywheel while spinning. So i have that mechanical advantage that sorta cancels it out right?

    Great video! I love the fact that he’s an advocate for replacing rather than continuingly regreasing older bearings. I’ve got a buddy who is so cheap he tries to get every last mile out of them, but you have to figure what your time is worth for a relatively low priced replacement item.

    What I took away from the video was that this guy has a vested interest in us buying new bearings rather than regreasing the ones we have on a regular basis to ward off rust and contamination, because if we do that they won't wear out for a long long time.

    • @GustavoSanchez64
      @GustavoSanchez64 5 ปีที่แล้ว

      You know that a 6806LLB NTN bearing is around 10 bucks right? A quality bearing does not have to be $300 bucks like ceramicspeed has you believe.

    • @mattsiviter430
      @mattsiviter430 3 ปีที่แล้ว

      You are incorrect, bike bearings are not designed to be maintained. The principle failure mode is through contamination removing the seal will easily damage the seal, cleaning the bearing is simply cleaning a bearing that has started to wear, putting clean grease back in will not be the same grease as the manufacturer recommends or in the correct quantity. Reapplying the seal will likely damage it increasing the chance of further contamination. To do all this with the bearing removed increases the chances of failure by removal and repressing the bearings into the housing. All to save a few quid. Daft.

    • @GNX157
      @GNX157 3 ปีที่แล้ว

      @@mattsiviter430 I put better grease in there than what came with it, and removing the seals with no damage is not a problem. Mine are clean enough and in good enough shape I can care for them as they sit. No need for pressing out. You want to replace, be my guest.
