Dogma disc...head scratcher

F10 disc w/eTap. Getting drive train (I think) noise when under hard load (i.e. uphill). Not so much on flat or soft pedal. Both rings.

I tightened the thru axles
I tightended the BB on both sides
I tightened the crank
I tightened the ring bolts
I tightened the rear der to the hanger
I tightened my pedals

Only thing not tightened was the seat and seat post. I'll try that next. Any other suggestions? Can't stand the noise!

RD slighlty out of alignment so the chain isn't in the center of the rear sprockets?

How many miles do you have with this chain and with these sprockets and chainrings?

Whenever I have a new chain or new sprockets it always needs a while until everything is working together without any noise from the drive train.


Or


Are your chain and your sprockets ok? Do they need to get replaced?

This is all a fairly new build. ~Four months on the road w/all new everything. I will say, off topic, the SRAM drivetrain is noticeably louder than Dura Ace.

Well after 4 months the drive train should be not new anymore. So that rules that problem out.

But depending on your milage per year and the way you use your bike (wattage and the sprockets used more frequently) 4 months coud already mean a replacement for the chain...

Have you checked if your chain is worn?

similar experience on my BMC.... I regreased the BB and did not hear anything on my last ride.

When I get more time.. I will pull the BB and apply the japanese wako lube (v160) and call it done.

I have a feeling this may be it.

I’ll try the seat clamp and post clamp first.

easy place to get wakos is ebay.. seller alex_japon is pretty quick.. I think I had the lube in hand in just under a week.

No reason why you cant use V160 on threaded BB

My F10 disk has a Dura Ace BB and doesn’t make any noise.

You’ve got a threaded BB. Grease, antiseize, whatever, if you’ve torqued it down properly I really doubt that’s the source of any drive train noise.

"Noise" is a little vague, but your bottom bracket is threaded, so I doubt that is it.

Under load makes me think something is flexing and introducing rub. I'd suspect the front derailleur, but could also be the rear slightly out of adjustment.

Since he’s mentioned tightening everything down I’d imagine it’s a creak he’s chasing.

I’d just point out that simply tightening isn’t always the answer, some things like seatposts and wedges can creak at correct torque if they’re dry instead of properly greased/pasted.

More of a repetitive ticking than what you generally hear from a creaky seatpost (as an example)

Under heavy load.... actually, it could be your saddle. If you push hard you can get some saddles to squeak.
It could also be the saddle clamp or rails....
