rotor 3d creaking
Moderator: robbosmans
hello
I've been with a problem that start to leave me nuts. my training bike is a specialized roubaix sl2 with a rotor 3d with power2max. the crank is constatly creaking from the bb area. when i clean and lube the bike if i loose the screws of the cranks and tightening everything the bike is ok, for 2 or 3 days. then he start to creak, first only off the sadle but became worse and worse, i think the creak is with the right crank at 6 o clock or the left at 12 o clock, i really cant figure out. when i came at home i loose the crank tightening again and he stays ok for more 2 or 3 days.but the screws are well tightening even when creaks my lbs do the same clean and lube and said to me the bike is ok. but is not...
can someone help me
sorry for the bad english, but the google translator...

Hi Grouk,
What bottom bracket does the frame have? If its a standard BSA then I would remove clean and refit. IF its a press fit then I would remove and refit with some Loctite 641.
I would also try another set of pedals as I have found this to be the source of many bottom bracket creaking!
I think tightening the crank bolts is a red herring.
Let us know.
Cheers,
Lig.

Check and/or tighten your wheel skewers too. Seems odd that the creak is occurring in the "dead zone" of 6 and 12 o'clock. I think pedals are also a likely suspect.
I'm running bb30 rotor 3d+ and q rings with 6800 di2 - I've had an annoying noise like yourself since about 600 miles - somebody mentioned greasing the hanger etc
I've replaced the bb30 with no real difference lube lasts 30 miles then its back, ear plugs might help or just let it go till it fails or gets louder
Sent from my 16gb Mi Pad (it works)

buy spare BB for 6800 and you will get the tool
if you "touch" something and it's get better for a while - you touched the problem. Change Rotor chainset bolts for new (15€) , and mount it DRY ( chainring holes) , except thread : here use Loctite 648 - it's relatively strong retainer (green) , but there's no issues with unscrewing . tight them to about 8Nm ( same bolt order rules as car wheel tightening bolts ! ) and wait 2-3 days before ride. If that won't help, change bolts for FSA : they're bit softer alu , and prevent creaking .
Tightening : first make it 4Nm, then 5, then 6 …

I can be wrong, and have plenty of examples for that

Had the same issue with the same set up. Finally removed the P2M spider from the cranks, gave it a thorough clean (was full of Belgie dirt and sand) and reassembled.
Noise gone.
Seems the interface between the spider and the crank mount has enough of a gap for small particles to get in to when wet. Then once they dry, they creak. Annoying as hell! On an otherwise terrific setup.
Hope this helps.

So cleaning everything fixed a creak?
Amazing

press fit crap..
inspired these guys
The two frames that started the idea (beyond Gary’s Wilier) were the Specialized OSBB and Cervelo’s BBright, which they say were notorious for having bottom bracket interface issues.

The guy has a threaded bottom bracket...this entire thread has nothing whatsoever to do with anything press fit.
