Oooooof that joke burned up on ascent....

[@AQWorldsLPC3675]

Jesus, that is literally the worst mechanicing (if that's a word) I have ever seen!!! I have always been a bit suspicious of Hambini but this train wreck means I cannot ever take him seriously again!! I would honestly sack any mechanic working for me for practices like this! Thanks for highlighting this.

Thanks for the informative video on what not to do on a headset service!

[@reginaldscot165]

Well, you can thank Hambini for that. 😅😉

[@jamesf8864]

Wow, this video has just blown my mind! I had never seen that Hambini vid, but yikes 😳 I swear about 50% of steerer bearings out there are under-preloaded (loose), and about 40% are over-preloaded, leaving a sliver of bearings out there actually operating as they should be. That was painful watching Hambini cranking his up so tightly, and crazy to think that that same person actually designs and sells bearing systems (bottom brackets). Not only that, but he has taken on the mission of producing remedial bottom brackets to fix everyone else's flawed designs. That was an eye-opener!

[@reginaldscot165]

If you think that was bad you should see my other videos on him… 😳 But only if you want to get more shocked. 😅

[@jamesf8864]

@@reginaldscot165 This was the third Hambini-bashing video of yours that I watched. One comment said that this headset vid of his might be from 7 years ago, so it's feasible that he's learnt a lot in those 7 years, but it's still surprising to see an engineer treating bearings and an assembly in this way. His unsympathetic use of hand tools is also concerning, but then I see a lot of engineers operating tools in this way! My experience is that it's rare for modern engineers to be good at the theoretical AND practical aspects of engineering, which seriously needs addressing. I can't blame you for meeting fire with fire after he tried to call you out. I hope you manage to continue keeping these vids more technically critical than personal and retalliatory 🙂

[@peglor]

There's one subtle issue glossed over in this video that is worth mentioning - the clamp bolts on the stem should be tightened and loosened incrementally, alternating between the 2 bolts, in order to ensure the loading on the clamp is reasonably even from top to bottom at all times. A quick thought experiment to explain why - If both bolts are initially evenly tightened and one is loosened completely, then the remaining tension (Which is more than the tension either bolt was carrying while both were tight) is carried entirely by the remaining bolt, leaving the bolt and more importantly the clamp loaded significantly more than they were when both bolts were tight. Similarly, when tightening the bolts, if you tighten one bolt up to the recommended torque and then tighten the second one, also to the recommended torque, the first bolt will now be loose. This is not mentioned even in the official instructions for installing a lot of parts with paired bolts on the same clamp, so you can follow the official installation procedure to the letter, using a torque wrench and still have a dangerously installed stem with a loose stem bolt afterwards. A scenario where this is even more important is on Hollowtech II crank pinch bolts, where the bolts are even closer together and in the much stiffer clamp at the end of the crank. It takes a little longer to tighten and loosen paired bolts like this (Especially on cranks where you usually have to spin the cranks 180 degrees for access each time you switch bolt), but at least you can be sure they are sharing the load evenly and the part is firstly clamping firmly enough to stay in place and secondly that the stress on the part is carried evenly across the clamp as per the part's design. Speaking as both a very well qualified mechanical engineer and someone who worked on and off for over a decade as a bike mechanic, that Hambini video is absolutely shocking from both sides of the fence. One trick I have seen, and even occasionally used, with GT85/WD40 is when MTBing in extremely muddy conditions is that spraying the downtube and chainstays with WD40 just before going out riding in thick mud does stop mud sticking to the frame, for a while at least.

[@reginaldscot165]

Excellent comment and a very interesting point about the bolt tightening process. I must admit that I do know that you should follow that protocol, but sometimes I don’t… for the cranks I almost always do, it’s become second nature by this point. Thank you for the detailed explanation. Always good to hear from an expert. 🙏🏻🙂

[@82vitt]

Shimano manual for their 105/Ultegra/DA groupsets does say the tightening of those crank arm pinch bolts must be done incrementally. I always initially use just an allen key for the first coupe turns until the second bolt stops getting loose when I turn the other one, then switch to a torque spanner and do them up alternately to 3/6/9 and finally 12Nm. For stem face plates where there are mostly 4 bolts the tightening is done incrementally in a diagonal pattern too.

[@hugonotti9192]

The backwards brake pad is telling. As an engineer, I'm an electrical engineer, your job is ALL ABOUT DETAILS. Small details. Large details. All of them. The more critical the detail, the more attention you pay. If you're a good engineer, this mindset is ingrained into everything you do. If you're not a good engineer, well, you might mount brakes backwards.

[@jimbo9030]

Also, why did the compression plug have to come out, especially if your going to bash on the steerer? Leaving the compression plug installed at least means you're hitting metal and not raw unsuppored carbon. Also how he just keeps bashing it risking the compression ring to gouge into the steerer 🤦 Just a little tap to get some play and then push the steerer back up to release the compression ring from the bearing and the ring just slides off and the steerer drops. Also just clamp the seat post and tilt the bike down and that way nothing can fall anyways. I've never seen an "expert" litteraly get every step of the most basic maintenance task wrong 🤦

[@simonalexandercritchley439]

Specific greases and weights are needed for each application. E.g ti prep for titanium etc. Where 2 different metals contact each other there is galvanic corrosion. Water and salt is the catalyst therfore cleaning and re-greasing is needed more in wet or dirty conditions. This maybe stating the obvious but it is often neglected.

[@reginaldscot165]

I totally agree. He recently started that he had never herd of corrosion with aluminium and stainless steel… can you believe that coming from an aerospace engineer?

[@kajkob]

@@reginaldscot165yikes, can you link where he says that? Find that pretty shocking

[@MartinE63]

It’s not just road salt, Hambini lives close to the sea, in the well known aerospace capital of the UK, Grimsby😀 That regular ride to ‘the oil refinery’ exposes the bike to wind blown salty sand from the Humber estuary. A few weeks commuting in those conditions and any bike will experience corrosion. Grease would indeed help, GT85, a more expensive version of WD40 aka kerosine with added teflon doesn’t.

[@reginaldscot165]

I also live by the sea in a very humid climate, my bikes don’t look like that… 😐 😉

[@DaveCM]

I don't think so. I lived on the coast for several years and routinely rode parallel with the coast with the wind blowing from the water. I've never had anything nearly as bad as that.

[@zeez4178]

Obviously your just a part timer​@@reginaldscot165

[@vihuelamig]

It's not quite the same as WD40. GT85 contains PTFE which acts as a lubricant. In fact it's often advertised as a 'bike lubricant' although I doubt they intend it for bearings which are more appropriate with grease. For a general frame protector (steel) I use furniture polish, in other words wax. It's not long lasting so it does need to be done on a regular basis.

[@donpalmera]

@@vihuelamig I guess you shouldn't be spraying anything like WD40 or GT85 all over bearings as it'll dissolve the grease and you'll be left with whatever light lubrication it provides (i.e. not enough for bearings long term). If GT85 is sold as a bike lubricant I guess they would mean for the chain, cassette and so on.

[@MilosBalunovic]

sorry to brake your logic but your brake on pushing on the bolt straight.. you are wrong. if you have a rubber, tightened at the "entrance" of the friction force, as you brake harder, the tension on the brake pad will elongate it thin it out (reducing the thickness of the pad), and also start tearing it. the bolt of the brake pad is not meant to hold the braking force, but just the rubber insert not to fall out. if you have it as shown in Hambinies video, you will have compression in the direction of braking force, making the pad thicker and also it will be butting up against the insert holder. also you will have more pat material where your biggest braking force is generated... from most of the comments it seams that you are trying to find a way to make it look worse than maybe it is. 1st of, you assume the video is uncut and every part of the video, blt not being tight is as is... the wheel was supported by the tool drawer from underneeth... which you would see maybe... but to your credit you have a lot of good points and explanation

Hi there, 9000 series brakes have the set screw on the front. ~really they do, both the direct mount and center mount. Also a bike mechanic, I get things wrong all the time it’s easy to do with all the different standards. Pretty certain on this one with the calipers. It’s on my bike now.

[@reginaldscot165]

They do make some brake shoes with the screws in the front but only for specific frames. (For example scott foil aero bike) but if you look closely you can see that the blade that hangs off the bottom of the shoe is also pointing in the wrong direction. So this is the second bit of evidence that it’s on backwards. A quick google search will prove I’m correct. 🙂👍🏻

Not really a valid argument when you are showing other people what to do.

[@tristano1998]

Yes, this is a really strange thing what Hambini is doing here. Especially when you know how much precision and meticulousness he puts into his bottom brackets (of which i got a PF30, that works very well). Besides - i am a very thorough „greaser“ myself. I grease literally almost ANY screw on my bikes. Most important: The pedal axis screws! I had a case some time ago with a so-called bike „designer“ who sold me a bike where he had installed the pedals without any grease. It was almost impossible to loosen them later on. Never forget to put LOTS of grease on those threads…

[@reginaldscot165]

Grease is almost always a good idea, certainly in bike terms. I think the precision of his BBs is over complemented, especially when you consider it’s the very expensive CNC machines at his workplace that he uses for free to make his BBs. When you have industrial grade programmable equipment you didn’t pay for it’s very easy to make precise products. I know this from personal experience: I used to work with industrial welding robots. Now personally I’m terrible at hand welding, I can do it, but I’m just awful. However, when I plug a few numbers into a welding program for a robot that robots makes some beautiful welds that out class the work of a professional hand welder with 20 years experience! Hambini is the same, we see in this video that he is just awful with his hands, not even capable of the most basic maintenance tasks. But, he puts some numbers into a programmable industrial machine and then all of a sudden everyone is complementing him on his work. 😂

[@channul4887]

One thing I'd disagree with is the expander plug - the main purpose it serves is as a preload anchor for the top cap. In carbon forks it also prevents crushing but it's not its primary function. Some carbon forks don't even use it - depends how thick the steerer tube is, after all it's no different than the seat post which you can clamp with much higher forces without crushing.

HaHaHiHiLOL! How not to do it! That should be the title of Hambini's video! The sound heard when he tightens the top cap could be the expander being pulled up! I would of course also use a lot of grease, maybe a little Carbon Assembly Paste on the grip surfaces of the expander, and on the stem, if it can turn at the specified torque! I would only use copper grease if I had nothing else, because it is intended for things that get very hot, such as brakes on cars, and it is toxic! Otherwise I think you are 100% right Reginald!🤣😭😎👍

[@reginaldscot165]

Copper grease is my favourite, it’s fantastic for all metal on metal applications. (Not bearings!) and yes very resistant to heat. Smells bloody fantastic as well! ❤️ But yes don’t eat it! 😅 Thank you! 🙏🏻

[@Andy-co6pn]

Copperslip is indeed intended for all metal applications as Reg says. For hi temp applications like glow plugs I'd use ceramic grease. Interesting fact about copper "grease" as it isn't really a grease at all, just an anti seize paste. Copperslip is compressible, unlike grease

[@peglor]

@@reginaldscot165 Exactly right, but it's worth explaining why - copper grease isn't really grease at all, it has a very carefully engineered grit particles in it to maintain a gap between the materials its spread on to prevent parts from galling or corroding into each other, while the liquid part of it keeps water and other contaminants out. It's ideal on threads (Pedal and BB threads maybe not so much because they actually do move in use, which is why the threading direction is different on each side of the frame, pedalling forwards tightens the threads due to an interesting engineering phenomenon known as thread precession), seat posts and anywhere else metal parts are clamped together and left in one place for long periods while exposed to a corrosive environment. Grease by contrast is all liquid with no particulate content (Unless you count molybdenum disulphide or graphite grease, in which case the particles are the lubricant (Same story with PTFE grease too, but since it's worse at resisting contamination, doesn't clean off properly with degreasers and we already have more than enough of of those chemicals in our bodies without letting ore out in the world, it should be avoided like the plague). While normal grease works in all the places where copper grease can be used (Though not as well in extreme wet environments and it absolutely should not be used where things get hot like on brake systems as it will flow on heating), grease also works where parts do move against each other in use, such as in bearings.

[@appelflapdrol]

Temperature resistance is just a subsidiary feature of copper grease, most important is the layer you create between different types of metal or between carbon and metal (aluminium in particular) to prevent galvanic corrosion
