ZTTO BB92 BB86 threaded bottom brackets.

[electrolux]

Hi,
I have installed a ztto BB86 threaded BB on my new frame (Speeder Cycling SC 52D), but after a few rides the bb is creaking 
Any of you experienced this and found a solution ?

I have the ceramic version, and the crankset is a Red AXS GXP. I just threaded the cups and installed the GXP adapter for the non-drive side.
On the Token Ninja I think a wavy washer is required on the drive side, but ztto dot not provide this washer so I thought it was not necessary ?

In addition to what was mentioned above I have seen some people use PTFE plumbers tape to take up any tolerances which solved their creaking. Can be an easy fix.

I currently have a ZTTO threaded press fit BB86 steel bearing BB installed in one of my bike frames. It's currently working great! I have a few questions if I plan to upgrade the bearings:

1. Can I leave the cups/sleeve in place while removing the bearings?

2. I'm presuming I would need to use a press fit tool to install new bearings?

If it requires removing the whole assembly again, maybe it's better just to get a brand new BB instead (though somewhat wasteful).

thanks for your inputs electrolux and carbonazza, actually the noise came from the nds crank arm, the 8 mm bolt was loosening itself during rides, especially when I was out of the saddle. I had to re-tighten it regularly on the fly during a bikepacking trip.
When tightened, the crankset did not spin freely but I do not know the source of the issue. I did not want to carefully investigated this, and replaced the ztto bb by a token ninja lite, and now I think this is working properly.

1. Most likely.
2. Yes.

How are those BBs holding up guys? I don't wanna instal another pf dura Ace bb and was considering the threaded one like this. Easy to put better bearings and it should work great. Would be way cheaper then buying something better then dura ace like bikone

I have a T47 77mm BB from ZTTO and it has been great (so far) has only done a few thousand kilometres. Install was very easy. Bearings actually seem decent.

I have a MTB frame with a misaligned BB shell (F*CK you OG-Evkin) and have been struggling with it for a while. Tried a lot of different bottom brackets and retaining compound up to the point where the BB shell is now oversized because of all the play etc. of the bottom brackets.

As a last resort I tried the ZTTO thread together BB with a lot of high strength retaining compound and this has been fine for a while now. The bearings are holding up already a lot longer than I was expecting (after a lot of muddy MTB rides) and the crank is now spinning smoother than any of my other bikes.

I have 3 ztto BBs and all of them had play between bearing and crank axle from the start. I though the bearings were bad but turned out it was because of the undersized plastic bearing covers. I used some electrical tape on the inside of the sleeve on one of the BBs and it worked ok. For the other two I ordered different plastic covers.

Overall these BBs are ok for the price. I found it to be a little annoyiong during the installation: rubber orings tend to move out of the groove. I also installed Token Ninja on one of my bikes and in my opinion the design on Token is much better. It has an interface covered with some kind of plastic similar to what shimano pressfit BBs have that makes it a bit more forgiving towards the bb shell shape and it requires way less effort to install

Long term review. Very happy with these c.12 eur BBs, whether from alibaba or alix. i had one die on my LT268 after 5+k km, i put liqui molly 3312 all over and the creaks went away for weeks. When they came back i installed a new one, with liqui molly from the outset. it's been flawless. Video with the new BB + molly, weeks ago. I'm at c.9k km now, includes plenty of mountain riding on dirty roads, and a good deal of road spray, even if i do my best not to ride in the rain. I'll go ride if the roads are half wet.
I've installed several more and nobody's complained yet (they ride less than i do).
For the price, i'd rather change them regularly than spend several times more upfront for the hope / belief that a more expensive one will last longer. Unless and until i see credible evidence that you can save more than a fraction of a watt with something fancier.
I do have a friend who recently changed hub bearings with ceramic bearings though, and... he has to change them already because the ceramic balls are into the bearing and there's play. He's furious at the bike shop who sold him these saying they were worth the cost.

I have gone through two of these as of late. I need to do more diagnosis because my ZTTO 30mm>24mm BB worked greated for thousands of miles. They are dirt cheap though. The problem I have is using my Cannondale Hollogram SL2 crankset into a T47 30mm BB. Both BBs work okay initially but after a short while begin making endless cracking noises like the bearings are completely shot. Recently bit the bullet for a WheelsMFG BB of the same kind and after the same mileage doesn't have any of the same issues as the same ZTTO variant. So whilst I am not sure of the cause, it seems to be related to the ZTTO BB and not my setup. Overall, I'd still fit a ZTTO one if needed due to how cheap and easily available they are to the UK from AliX.
