Miche Primato Bottom Bracket sucks - London Fixed-gear and Single-speed

johan · 15th August 2008

Useless piece of crap, unscrewed itself halfway into the city. Had to fucking walk back, stay clear of these BBs.

andyp · 15th August 2008

User error in installation? That's normally what leads to a bb unscrewing itself. Been there, done that.

johan · 15th August 2008

How would I install it wrong? To loose?

andyp · 15th August 2008

Potentially yes. Is the frame italian threaded?

johan · 15th August 2008

Yeah, Italian, but my prior shimano BB did not unscrew itself. And I tightened the miche up as hard as possible.

andyp · 15th August 2008

It's worth investing in some thread lock compound if you can find some. I had an aluminium Pinarello and no matter how hard I tightened the fecking bottom bracket it would work loose. Thread lock solved it.

adoubletap · 15th August 2008

Halfords for thread lock

johan · 15th August 2008

I think I'm going to go for a BB that has one fixed side and one loose side, and not an adjustable one.

hippy · 15th August 2008

I never had any trouble with mine. Did you grease the threads before installation?

johan · 15th August 2008

Yes, plenty of grease. Maybe I'm too weak and couldn't tighten it up hard enough :S

eeehhhh · 15th August 2008

Mine is fine. Lightly greased the threads. Done up to specified torque with a torque wrench.

I'd put it down to not being done up tight enough.

johan · 15th August 2008

and what sucks even more is that I have to take the tube into town to get a campag BB tool...

Dude, I have one you can borrow. Hit me up via PM or SMS or something (number in thread).

MrSmith · 15th August 2008

i had trouble with mine, cup on driveside was rocking loose in the shell. swapped it for a campag with a flanged cup.

Sharkstar · 16th August 2008

I fitted one this morning. Now you've got me worried.

fred · 16th August 2008

every thread unwinds itself of it's own accord, eventually.

h2o · 16th August 2008

I have miche bbs on two bikes. On one i used some teflon tape to ensure snugness after one side unscrewed a few times. No problems since.

Learning how to service a bike should not equate to using your credit card whenever something goes wrong. That's just mindless consumerism.

miro_o · 16th August 2008

Was it installed with the right tool (the campag one)?

stevo_com · 16th August 2008

inferior grease........

rocksteady · 16th August 2008

been riding mine for a week now, no probs whatsoever

johan · 16th August 2008

loctite on, i'll give it 2 weeks ;)

willski · 16th August 2008

Swapped my Sugino for a Miche last year and I wouldn't go back. The Miche has run sweeter for longer and is much more resistant to the rain.

johan · 16th August 2008

Wouldn't that be because the miche is sealed while the sugino is not?

This one is heading that way.

My Shimano BB unscrewed it self in my Italian threadet frame.. So I'd recommend that you don't use Shimano either ;)

(I AM ironic, I recommend you use Loctite and HTFU)

kowalski · 4th September 2008

My Mickey BB had to be beaten like a chav on a Friday night to get it undone.

The bearing is, however, a sack of spanners. 600 miles on a modern sealed BB is frankly pathetic.

I'm led to believe they're out of the same Kinex pot as the CampagNOlo, so I'm not keen on trying them either.

h2o · 5th September 2008

I've been running a Miche BB for more than double that and it's still fine. *shrugs*

gabes · 5th September 2008

johan, get a phil, you can...

Emilia · 2 Weeks Ago

Hmmm, my Miche BB has just started to unscrew itself, as did its predecessor, only about a month ago. One was fitted by me, one by someone else, so I can't blame the mechanic. The one on my Surly (RIP) was fine for over a year.

Is there any chance it could be something to do with the frame?

miro_o · 2 Weeks Ago

Perhaps the threads are just cut a little 'loose'. That'd depend on the tool used by your frame manufacturer and it's condition, and I guess the material qualities of the BB shell.

C'est la vie.

fred · 2 Weeks Ago

italian or engrish thread?

Not a clue. English, I assume, since I didn't notice anything unfamiliar when I was fitting it.

It's making me even less fond of this bloody bike.

fred · 2 Weeks Ago

is this the condor?

Emilia · 2 Weeks Ago

Yes. I know I should be counting my blessings, but so many things have gone wrong that it's just getting on my nerves at the moment.

hippy · 2 Weeks Ago

Did you use a locking compound or grease or air on the threads?

fred · 2 Weeks Ago

try ptfe tape (30p or so from a plumbers merchant). about 5-10 turns on the threads, in the opposite direction to the threading. So, if you're looking at the bb shell frm the side of the bike and gonna turn the bb cup clockwise to tighten it, put ptfe tape on it anticlockwise. you still need to grease the bb.
