I had all this BS with the bike shop and wheels Manufacturing when I bought one of their PF30a centre threaded BBs. It was loose in the frame and clearly undersized coming in at 45.92mm. Wheels fobbed me off with the BS that frames are all over the place as if that was an excuse for them turning out BBs that were out of spec. Their next one was to tell me that the cups needed to be greased and that the thread centre tube was to be tightened up to clamp the bb in place across the shell. This is of course BS because a pressfit should be carrying the load by radial interference fit and should be fitted with compound between the alu BB and carbon frame (I know this because I have several contacts at Henkel through my job and have dealt with them in various design queries, and they know what they’re on about). Wheels continued their nonsense but wouldn’t accept my push back even though I’ve spent nearly 20yrs in engine design and know a thing or two about fine tolerances, such as crank bearings. Anyhow Hambini sent me a gauge to check the BB bore on the frame and was just in spec, so wheels got their scrap aluminium BB sent back to them and I bought a Hambini BB instead in Sept.2021 - fit and forget. The simple fact is consumers shouldn’t be having these arguments with component suppliers; and we shouldn’t have to wheel out the technical explanations to prove the issue. It’s fine if you can do that but many people can’t and they’re getting rinsed by customer service bull shitters and companies that know full well their products are crap.

I'm excited to see your take on ZFC. I used to be a big fan of his, but one thing bothers me. If lubricant brands pay him to test their products, how can he claim his results are unbiased? Are we supposed to believe he's immune to that influence? He even boasts that some brands hire him so often he offers them discounts. If he published negative results, he’d risk losing income-naturally, that would make anyone favor certain brands. *Cough cough Silca* Yet, people always refer to him as the only independent tester out there. Am I crazy, or isn't it true that once you accept money from the brands you're evaluating, you lose the claim to being an independent tester? In real science, those results would be dismissed due to conflict of interest. I used to be a big fan, but after testing a lubricant he criticized and finding it completely different from his assessment, it’s clear something’s off.

[@RReese08]

Based on my experience such as it is, the source of all that’s good or bad between a manufacturer, their product, and the customer, usually starts with whoever comes up with ideas for shit like this. And then it’s passed on to the designers and engineers along with a budget that they have to live with to make it a viable product for retail sale. In most cases the result is shit and the customer service who are in the trenches are left to fend for themselves with just their dicks in their hands, because the other individuals in the chain of responsibility either don’t care (because they’ve done their job) or they’ve been thrown onto other tasks. This doesn’t include marketing whose job is to push product out the corporate sphincter. In an ideal world, customer service gets the backup it needs from design and engineering if/when there’s a problem with product. But with the bicycle industry, such things are virtually nonexistent. And people in the trade wonder why consumers hate on things and end up seeking responsible and knowledgeable types for solutions that manufacturers should own up to.

[@tychoMX]

These are my favourite Hambini features: "the manufacturing is crap and is done by clowns AND this is how I fixed it". Question for the preload - would it be possible to add the washer on the other side? I think I did something like that with a CX bike that I originally had as 2x in front. There was not enough clearance with my preferred front derailleur (FSA energy, wide range) on the inside. So on the crankset I put the wave washer on the non-drive side. Not sure if this was best and probably could have used spacers instead (have a very good set of many different thicknesses!), but it's currently ok. And better than the usual mess with my other SRAM cranks where adjusting spacing/preload is much more complicated because of their "we only adjust on one side" system. EDIT - ah, saw that the preload question has been answered already. Thanks again! And from all these videos what I've learned is stay away from 30 mm cranks like the plague.

[@PeakTorque]

Crikey its like a 30mm gxp. Yikes. Did he/she/it try and run it without the wave washer and no preload? Have run gxp without the wave washer, not ideal for bearing life but would have solved the bearing seat width issue. Preload by displacement is prone to binding if there are differential temperatures but seeing as everything is alu cheese it should be good 😂

[@Hambini]

I'll refer you to Karen in Infocrank customer service who knows all about preload...

[@Mapdec]

I have a question 🙋‍♀️. Could you have simply moved the preload washer to the other side of the bearing like a Campagnolo assembly, or was the seat too shallow?

[@Hambini]

@@Mapdec It's a stepped shaft so I don't think that is possible. It's essentially locked at the non drive end like GXP and then the preload is at the drive end. What irritates me more is the fact they referred me to praxis and then the landing was obviously shorter - I think it's a defectively machined crank but infocrank don't seem to want to acknowledge it. And these things are so rare I don't have a large sample size.

[@MrJx4000]

Nothing like the Cartridge Bottom Brackets for longevity and ease of replacement.

[@MrJx4000]

@rollinrat4850 You said, _"If you need to use a hammer to tap the crank spindle through the cups, you have an issue. The two threads are not concentric and or the faces are not square and parallel"_ I don't mean to argue with you but it's the threads that establish the orientation of the bearings, and not the frame's BB face, right? Those threads fit very tightly and there's no way a mis-aligned face will ever alter the bearing's orientation. So the two threads have to be machined concentrically in order for those hollow tech bearings to be aligned such that there's no need to hammer the shaft into the other bearing. That's why those cartridge-type BBs were better IMHO because you have one thread that's metal (on the cartridge itself) and the other one is a non-metallic material of some kind--it will allow for a certain amount of inaccurate machining of those those BB threads. I'm dealing with this very situation on my new Surly frame right now.

[@MrJx4000]

@rollinrat4850, Holy shite! How long did it take you write all this?

[@MrJx4000]

@rollinrat4850, well, well, look at what KZbin just included in my recommended videos today: *_"It's on the Inside That Counts | Tech Tuesday _**_#158_**_"_* This is 4-years old now and is somewhat applicable to our discussion. You can't post links in YT comments but the title is okay I believe. My new Surly frameset that I bought has those BB threads off kilter. I ran the proper threading taps to chase the threads and then tried assembling the bearing cups and shaft--the bearing cups were not aligned. I wasn't going to pound the shaft in with a hammer so I gave up for the time being (this was last summer at a community bike shop). Surly sells this frame in a complete bike assembly (the Preamble) and uses square-taper cartridge-type BBs. They work fine. I've seen this assembled bike in my LBS. I'm going to try chasing the threads again to see if that helps but if the hollow shaft will not slip in easily on the other side, I'll have to go to a cartridge BB. The threads are what align the bearing cups, and no amount of face machining will change that. Machining those faces only eliminates any gaps that might appear and possibly allow for moisture to seep in (I know it'll get in anyways but you do what you can to minimize it). And thanks to the Great Hambini, I would've never known that these manufacturers will produce the kind of "shite" quality that they do.

[@MrJx4000]

@rollinrat4850, yeah, that frameset is not returnable because it was on sale last year. And as I said earlier, it'll probably work fine with a square-taper cartridge BB so they (Surly) will probably not accept responsibility. The only thing I can think of is to heavily "chase" both BB threads to see if that allows for a better alignment in the bearing cups. If that doesn't work, then it's goodbye hollow tech BB and hello cartridge BB. I'll let you know how that works out when I get around to it again.

[@LincolnRobinson]

Am running two BSA frames, so Praxis M30 BSA BB. So maybe BSA is less prone? Shouldn’t be from what you’re describing! 😊

[@peglor]

What's really strange about this design is that the wave washer looks to be loading the whole face of the bearing rather than just the inner race that spins with the crank and spacer, unless the spacer is shaped to transfer the load only to the inner race. It looks like a rectangular cross section ring, but this could be subtle. Tightening the tolerances a little and adding a Belville washer instead of the wave washer might be a fix that gets more of the bearing on the bearing seat on the axle and will accommodate wear without play instantly appearing, but I don't know whether these washers are available off the shelf to do this - getting custom parts made would be very expensive per crankset unless you were doing thousands of them though.

[@jaro6985]

The spacer has a lip, so the outer race is cleared, which you can see in the video. Praxis wouldn't mess something simple like that up. I don't know if they make bellvilles with low force ratings for this application. Maybe higher would be OK though..

[@peglor]

@@jaro6985 A very thin belville washer will have low spring force as well as taking up minimal space along the axle, so it could meet the requirements for this perfectly.

[@ScrubsIsee]

Thnaks for the video. One question remains from my side: What exactely is the (engineering) benefit of the preload washer - compared to the screwed preload of shimano? Shimano doesn't use any preload washers on their HT-cranks. It also looks for me as if these stepped axles are ay more complicated to manufacture, than a straight hollow tube with a threaded end …

Having one bearing seated and the other floating seems like a pretty shit arrangement - but hey what do I know. Surely both bearings properly seated would be stiffer and more desirable?

[@jeffbrunton3291]

Great stuff as usual. No idea oni the technical details really, but surely when praxis supply this to Infocrank (i assume), they should start making the bearing seat a bit longer. Is it just as simple as them removing less material when they CNC the material? And i think you said the problem is only on the power meter version not the version without sold direct by Praxis.

We have taken that into account in the design of IC2 and this is made in a ‘hollow' box shape design, in order to be stronger in the twisting directions, as well as the normal pedalling direction. We believe this will give the IC2 a longer life for all cyclists, no matter their style."

On my praxis works BBs the NDS bearing has a little sleeve insert reducing the ID and accommodating the step down of the shaft. Does the infocrank implementation have this?

[@Hambini]

Yes, no problem on the non drive side, it's only the drive side

[@tednruth453]

Info crank's electronics are good, they made the mistake of teaming up with Praxis.

[@kipcc3918]

If praxis makes the crank arms, Who did the spindles? So the powermeter is crankbased or spindle based? Seeing where the error was the bearing seat? Or I’m wrong here? 😅

[@bryantaylor1983]

The parent company of Praxis made the cranks, the spindles, the chainrings and the bottom brackets. Verve designed and made the power module. And it was done nearly 10 years ago.

Why pick on poor Adam at Zero Friction Cycling, he is one of the better ones?

Because he is a snake oil salesman.

@@RPatonno, ZFC is a snake oil salesman. Chain waxing will keep your socks cleaner, but it’s garbage for sliding friction lubrication .

[@tstigge]

​@Hambini you say snake oil salesman? I would be interested to see how you back up this claim with any data or proof.

[@johnkasza2315]

Adam at zero friction at least has the CLASS to communicate with a person or company to discuss different opinions..to start name calling shows WHO THE REAL WHANKER IS...time to grow a pair..even 5 year olds grow up, at least physically

[@Randombourg]

What about absolute black on your scale?

[@borano2031]

Needs a different scale?? Rgr

[@Alan_Hans__]

I know significantly less than a 5yo but could the preload be on the inside. The full width of the bearing onto the landing and maybe a sleeve from side to side so that both bearings are loaded.

[@Hambini]

that's how I've done it but the praxis manual which is on their website shows otherwise.

[@MrJx4000]

Great video.

[@Twisty1024]

Can the average punter just buy a stack of bearing shim washers and use those to space it to the correct tolerance?

[@drayzen9678]

Yes, though you need to add more shims over time to take up play introduced by bearing wear, or regularly replace the bearings. That's why they use a wave washer (essentially a form or spring) so it automatically adjusts.

[@robertfontaine3650]

The part where this can't have every worked is a bit confusing. This should have been an RTM NFG. Does their recommended bottom bracket solve the issue? Double checked their web site and they claim perfect fitment with a Shimano bottom bracket.

[@jaro6985]

Thats the infocrank IC2, not this one. Their newer crank uses 24mm steel spindle, probably because their old one was crap, and shimano's patent might have ran out?

[@__uorson]

what does "fobbed off" mean?

[@PeowPeowPeowLasers]

I'm not an engineer. Could you not build a shim to extend the shoulder? Something split in two, that extrudes from a bearing-sized block of metal, held together with a couple of bolts, that clamp it inside the bearing, inside the bb shell? Again I'm no engineer.

[@Hambini]

it would be ~0.05mm thick, you'll have more luck with single ply toilet paper

[@MrJx4000]

You're right--you're definitely not an engineer!
