Update regarding cassette. 34t was still rubbing ever so slightly on 1 and 3rd gear. So I had to go lower to 32t which is now perfect. 11-32t 10s. Also removed spacer on crank hub so the chain line is slightly inside. Shifts fine, no issues so far.

After changing elastomer from mid to hard I noticed that mid elastomer was deformed so the rear fork was actually lower than it’s supposed to. I think this was one of the reason why 34 cassette was still rubbing. Add my 100kg weight to that mid stiffness deformed elastomer and you will have lower than average fork position which brings the chain closer to the rear fork. I believe lighter users with stiff suspension block may get away with 34 or 36t cogs. However extra weight needs to be factored in, so for anyone thinking of installing more than 32t cogs I’d recommend testing for chain rubbing with fully loaded rear rack (15kgs).
