Hi everyone,

I just bought a 2020 Robaix pro (SRAM force etap ax's) and I have the same issues that have been mentioned here. I wish I would have found this post before I purchased the bike:( so far it seems the cassette is the culprit? To me it seems like it's that new style of chain, when listening to try and isolate the noise it seems to be coming from everywhere along the drivetrain. As has been mention my main concern is the vibration, loss of efficiency and possibly of chain loss. Any input would be great

Kirk
The cassette was the main source of noise in my case -- I tried 3 Force cassettes for 300-400km each, all noisy. Then I got a Red cassette from my LBS (Force cassette RMA'd to distributor) and 95% of the noise went away.

So, contact your LBS, let them know about the issue and that the fix is a red cassette, they should be reimburced by SRAM or their distrubutor.

I would remove the chain and soak it in degreaser. The stock lube is way too thick, making most of the noise.

Thicker lubes act as sound dampers. The only way thick lube causes more noise is if solids get stuck to the chain, and this isn't the sound I hear from 12spd SRAM road cassettes. It's too regular/patterned.

Red cassettes are very expensive. i don't think Sram will upgrade you cassette for free.

I think the claim was that a LBS swapped it out. I dont think SRAM would do it. But maybe.

I dont think Canyon would but maybe i should try.

For those interested of getting Sram red/force AXS groupset or upgrade kits, Rotor makes new - 4 Spyder chainrings with 110 bcd.

They fit Shimano 4 bolt cranks and you keep the bottom bracket as well, assuming u have Shimano cranks...
They also fit Rotor Aldhu spyders and couple more of their lineup.

You also get to keep your power meter, if u have one on those Shimano cranks.

They have round and oval rings, both in 48/35 configuration.

I already ordered the oval ones they should come on Monday.

Will report later on for fitment and shifting performance.

They are around $100 for 48t and $50 for 35t.

Weight is not specified, but according to my calculations, Dura Ace cranks with these rings should be in the 630 grams range...

Heavier than Red,
But way lighter than Force.

Hello everyone, I've recently bought a new bike equipped with SRAM Force Axs, and at the moment I'm having quite some trouble trying to identify what could be the source of a squeaking noise coming from my BB/crankset... Don't know if anyone have experienced this already, but here's a video trying to describe the problem, can provide some more if needed. Video. Already added some more lubricant to it, which solved the problem for some time, and at the moment, every now and again it comes back for a while.

That sounds horrible. Wouldn’t ride that anymore. Chances are you are grinding down your frame due to misalignment.

(not a home mechanic), I can ask my LBS to see if it's some sort of misalignment... may or may not solve the problem, worst case scenario I take it back to where I bought it (after this pandemy shenanigans) is gone, since rn it's recommended to only leave home for work and essential shopping here
