Spirit of that group cycling (5)

Ross

I believe the answer is:

ethos

I'm a little stuck... Click here to teach me more about this clue!

'spirit' is the definition.
(I've seen this before)

'of that group cycling' is the wordplay.
I cannot quite understand how this works, but
'of' could be 'o' and 'o' is located in the answer.
The remaining letters 'eths' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for ethos that I've seen before include "The distinctive spirit of a culture or an era" , "Moral significance" , "Those with characteristic community belief" , "Cultural spirit" , "Moral atmosphere" .)
