Does anybody know what is the maximum biggest cog size possible ? I have now 32t, would 36t ou 40t fit?
P.S. : this cassette and the XDR body are road/gravel components, not MTB components.
With the default 52T chainring, we can only go with 11-34T cassette max. It was proven with the original B3 10SP Sports model from Pacific Cycles that was on offer 6 years ago. This model has been discontinued.
If you are considering to go with 9T-44T cassette, you might have to consider moving onto a 48T or even 44T chainring for a single chainring setup. You will be getting higher top and low gear ratio but high gear gap as you might already know.
My 3x10 Touring Birdy 3 is using 44T and 11-36T combo without the chain rubbing the rear fork.
I have a friend with a Frankenstein New Birdy Classic running 44T single chainring pairing with a 9-46T cassette. He initially used a Zee RD and eventually switched to SRAM Force AXS XPLR RD. (He replaced the stock v-brake forks with Birdy 2's disc brake forks.)
