Please get more people who actually know what they're talking about on the channel. Someone who actually knows aero (incidentally, Hambini could do that too), stiffness, etc.

I know hambini from some of his vids. Very nice to see him on the GCN tech channel

I loved every minute of it! Thanks for having me.

@@Hambini Great to see you on GCN! You should be a regular... #AskHambini

Nice to see Hambini on. 👍

I didn't know he could speak for more than a minute without spouting an obscenity or three.

Had him on a short leash

The first 5 minutes of the video took half an hour based on the watch time. so there was a lot of swearing cut out XD

there is a guy with a gun pointing at him and he said he will shoot if he swears

Not a single cunt was called out lol

just watch hambinis own channel

Well said

I think this would upset the sponsors and their marketing department

@@0GekkeGerrit0 might be, but regarding Hambinis critique of SRAM, I dont side with him on that one. SRAM might have inferior quality control but their ideas are sometimes brilliant and made Shimano to stop slacking so in the end a part doesnt have to be mechanically good to be a great product for cycling if you follow my point but its very interesting to note the difference between cyclist and engeneer thinking.

Gekke Gerrit No shit! There is so much marketing hype and BS thrown around. It all seems rather irresponsible to me. But thats why they retain lawyers! The lack of proper QC in the larger bike industry, particularly Asian made products is alarming. Certainly where it concerns safety. I know, I used to be an inspector both in Aerospace and at Rockshox. Ive also machined and built carbon structures for satellites. I know what to look for, it was part of my job. Now I wrench in a shop for fun in my semi retirement. I cut up crashed and trashed frames to inspect lay ups, voids, quality etc, Just out of curiosity! Quality varies widely and issues are obvious from mid to high end. I can demonstrate it to anyone. I am obviously forced to keep my mouth shut at work. I have been ‘been warned’ LOL! In 50 years of hardcore cycling I have seen a handful of steel frames that couldnt be repaired. Mostly because they just werent worth the cost. In 4 years wrenching in shops Ive seen dozens of plastic frames relegated to the dumpster! Needless to say, I ride custom metal bikes. I couldn’t afford a ‘good’ custom carbon frame and I don’t like the ride. Welds are easy to inspect without cutting them up! I get exactly what I want, I ride with my builders and I can witness my frames being built.

Hambini is the engineering geek..

"Never ending hype". Now there's an understatement! Akin to MSMBS!

GREETINGS YOU HAMBINI FAN!!

+1

I almost heard an alarm going off.

Ouch! There was no need for that Hambini!

Not only inside Jon!

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.

@@peglor I don't wash my bikes either. I wipe it down with a towel and will do some other spot cleaning but find any insane deep cleaning to be a waste of my time.

Hold my fancy coffee I can't even properly pronounce.*

Hold my wd-40

My chain broke reading this

Yeah that i would love to see

MARKETING hype 2 FLEECE the MASSES...🖖👋😱

Check out Hambini's channel

GCN level pun.

Good one.

ermm he sells them

@@sdqsdq6274 Come on mate, you can do better than that.

proper.... Let’s take a look at his LinkedIn, hmmm it says a nobody self proclaimed engineer

Cheers Robert!

Yes... another technical expert that truly deserves more attentions...

Oh please, oh please, oh please, oh please....

If GCN starts bringing more of these experts in they will start losing sponsors. GCN is a marketing tool. Expert engineers shred marketing BS like lettuce.

He can talk how he wants fella, no one is forcing you to watch. He's from the North, I'm from the South but his vocabulary rolls nationwide.

That's trued. Maybe they should have him on when he agrees' that a product is good, thus he will always be truthful and retain his honour.

Yes!!!!!!

Nah that's us, thanks to his teaching.

Michael McDermott glad your phone didn’t go under

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.

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.

@@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.

The grin was him trying not to swear every 30 seconds.

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.

Glad we could help!

Thanks!

They'll lose advertising if they do. Marketing has very little to do with engineering. Engineers like Hambini shred BS marketing claims daily. They speak the truth. Marketing is just another word for propaganda or brainwashing!
