He obviously talks very differently if it's serious business.
What evidence is there to support that?
based on private exchanges? He didn't curse and all that when doing standard customer service.
So, he doesn't curse when dealing with people who buy his product, but acts like a d-bag in almost every other situation? Awesome. That's a standard we should all aspire to.

I have had several discussion with him via email and private messages.

He is actually a great guy and not even close to the same person u see in his YouTube videos.

I just chalked it up to him putting on a persona for the internet in order to gain views. Honestly that's just the way social media is now and days....trolling, sensationalism and click bait.

C'mon, stop selectively responding to the points I've made. It's getting tiresome. He didn't even act like a d-bag on GCN's interview.

I've very clearly mentioned treating this as going to watch Jerry Sadowitz's Stand up shows. If you don't like what you see, literally don't engage it.

There are far more offensive things online. Don't take it so seriously.

And finally, based on my experience working in R&D in my earlier years, it's true that we have an acerbic/naughty tongue when comes to criticizing some times. The only difference is Hambini plays this up to 11 and use it as his brand of comedy.

Do you really need to register as a comedian before you can play as one? The whole schtick of good comedy is the ability to blur the lines between what is real and what is not. It's a bit like a magic show you see?

Understand that point of view ;)

Can't help with your particular bb sorry.
I have a token ninja on my Cervelo S5 that threads together.
I have previously had pressfit bbs in there that didn't thread together. First one was noisy. The second one shat the bed after about 25k km.
The token was reasonably priced and noiseless. Happy so far.

Curious what crank OP is using. I bought and am waiting delivery of an O2 VAM. I’m wanting to use my Easton ex80sl 30mm crankset. I emailed Hambini and he told me he doesn’t make a bb that would work because the Factor bb shell is not a true 79mm oibbright. Ended up going with BBinfinite which has a bb developed specifically for the Factor O2 VAM. Still waiting on the frame, but having a Bbinfinite bb in my Trek Supercaliber (DUB bb92) I’m looking forward to installing one in the new frame.

I can’t imagine why anyone would use grease for a one piece bb. Both Hambini and Bbinfinite clearly direct just the opposite.
Thanks for all the replies, I've not been able to get online for a couple of days

So the shop said they used Loctite 603 retaining compound with SF7649 activator, that did appear to be working ok for a while but in the end it didn't last.

I contacted Hambini in the first instance, but I wasn't sure how long it would take to get a reply as I imagine he's pretty busy, he actually replied the same day

Part of his response -

I’ve attached a drawing of BBright, this is supposed to be 79mm wide

Below is a link for the Factor version of BBright. They’ve called this BBcorrect

https://factorbikes.com/tech-talk-facto ... ostro-vam/

Our Industry Leading T47 BB Solution for the OSTRO VAM | Factor Bikes

The difference is the frame is not actually 79mm wide, it’s slightly narrower.

If you fit a Hambini BB into that shell, the bearing landings will not FULLY line up, you’ll be about 1.5mm down. Which will be a contributing factor as to the reasons why your bottom bracket is moving out.

Even with that, I suspect your frame is oversized and you’d need to use activator, retaining compound and then let it go off for 2-3 days before riding it.

Personally, I would not go beyond Loctite 641. Some people use 638 but you might find it difficult to get it out if you go to that strength.



So I'm still a bit confused, that's taking about the new ostro bb which talks about being different, the description of the 02 VAM is as follows - BB CeramicSpeed PF4630 Aluminium cups / CeramicSpeed bearings with Wheels MFG 24mm BBRight Reducers/Adapters

I purchased the bbright version of his bb because the spec looked right and the description said "This type of Bottom Bracket is almost exclusively used on Cervelo and Factor bikes"

Anyway this has all become way too much hassle, if my shell is indeed over sized I don't want to mess about trying a different retaining compound, as somebody else has said it might not hold it anyway.
I'm going with the wheels manufacturing one with some ntn bearings and hopefully that will work better for me, so thanks for suggesting that.

It was a rotor inpower crankset that was working loose, it was sent back to rotor for inspection as I assumed there was something wrong with it, but they've looked at everything and told me theres no damage.

Wheels Mfg bb comes normally with Enduro bearings, right? The ones i had through time were 24x7 bearings - these are not industry standard size.
I don't thing ntn makes these bearing sizes. If standard 25mm id ntn bearings are used (can't remember the digit code) you need a reducer spacer to get from 25 id to your 24mm axle size.

Hard to find, belive me (tried the same thin a couple of years ago). Hambini makes the tophat reducers (pricy), but they are not designed for use with other bb than his own, so your results in regards to bearing protection may me bad.

Another thing if you go with wheels mfg - the thread part was good in my case, but the inner bearing relive step (or what it is called) was badly machined - so the shell ended up pressing against the inner bearing shield at two spots, destroying bearings very very fast. Both sides. Sample size: one bb.

But you might want to check it before use (bearings nees tonbe removed to check this)

His ban is justified. Some lines are crossed which goes against the rules then I'm not going to stand up for him.

Try some loctite 609 with activator. Let it dry before riding. Should be good.

When it's in properly you shouldn't have to touch it again. The bearings are replaceable without removing the bb.

Here's another idea. What about roughing up the surfaces with something light abraisive before. Both the outside of the bb and the shell in the bike.

That makes no sense.

Yeah, which is why my first statements were:
I think there's plenty of evidence that "he who shall not be named" is either incapable of, or uninterested in, having a civil discussion on a public forum.

I'd say he interacts well with people that don't disagree with him.

But, you are standing up for him.

No more posts from me on this thread. My apologies to the rest of the forum for getting dragged into and participating in this pointless tangent.

First off I don't want this topic to turn into a hambini bashing, I've read previous threads which either ended up going way off point or simply closed.

Has anybody had any issues with his bb sliding out the frame? Initially mine was installed with grease, after the first ride I couldn't shift into the big ring which is where we noticed the bb had moved out of the frame by a few mm.
It was reinstalled with some threadlock, until now it seemed to be fixed in place, but it rained heavy today and towards the end of the ride it again moved out of the frame causing shifting issues.

Since having my new bike I have been plagued with crank issues, a brand new rotor crankset kept working loose, which we assumed was a fault with that, I've bought new cranks since and after the first ride there was a slight loosening of the new cranks.
I'm beginning to believe the cause of all my problems was this bb just not fitting tight enough in the frame.

If was fitted in a factor 02 vam, has anybody else any experience they could share?
Wait! What? Why did your bike shop use grease to install the Hambini one piece BB? This is quite literally the opposite of whats recommended by Hambini. You need to completely clean the shell, then use Loctite activator 7649 followed by Loctite retaining compound 641 (medium) and let sit no less then 48hrs. Did your bike shop figured this was correct? yikes!

Really out of line for you to hijack a thread by a guy asking for technical help by making multiple posts saying the exact same thing to further your personal vendetta against Hambini, even after the thread starter asked you all to refrain. If you want to criticize Hambini make your own thread.

If the shop first used grease to install a bottom bracket I wouldn't trust them to do a good job on subsequent tries.
I would do it myself - properly - or, if I'd given up entirely, go with the thread-together alternative by either Wheels Mfg or a Token Ninja.

P.S.- if it's clear that Hambini made a mistake on his answer, point it out to him so he can properly help you. He clearly will go the extra mile to help out his customers so why not avail of his customer service?

I think carbon resin would swell when grease is applied? That would surely affect the carbon frame?
