I just discussed with my mechanic, what he proposed is Shimano Deore XT Hub and 11-36 cassette. I’m not going to race it so 11 sprocket should be OK with 52 chainring and 36 will provide good ration for hill climb. Here are photos. Do you guys think this will do OK?
I assume Shifting system Shimano Deore Trekking, 10-speed derailleur coming stock on my Birdy will be a perfect fit.
