Other SOLVED: Specialized Levo (2018) Brose 1.2 Motor - Clunk Noise

[MarcusTwice]

I own a 2018 Specialized Levo Hardtail and has been a joy with zero problems until now.

Unfortunately it has developed a ‘clunk’ when pedaling under load in the highest gear (small cog).

Please take a look at the movie, as I need advice…

Thanks for taking a look.

Your chain ring jumps forward with each gunshot, which makes me think your freehub must be slipping a few ratchet teeth. I would take it apart for inspection and cleaning.

Mine did it too, the E13 screws of the motor had come loose.

I think it's just the smallest cog on your cassette is worn. So, the chain is slipping forwards one tooth then abruptly catching again. You could also check the derailleur adjustment and make sure the B screw is set correctly.

Are you riding in Baltimore MD?

All great advice, thank you so much.

I have ordered some removal tools and will keep you posted.

His location shows as "UK" ... so probably not !

There doesn’t seem to be anything broken, so will give it a clean, regrease and put back together…

SOLVED

There was a E13 screw loose on the motor but the main issue was the smallest cog on the cassette.

I’ve purchased a new Shimano XT cassette and it now back to be smooth as silk.

Thank you, for all your suggestion.
