well at least for the time being I am going to be running a 16t in the back with the triple in front (42 34 24), so I should have a big choice of gears to choose from assuming the chainline works. I know I'll want to take off the triple soon enough though (I'd like to get a bash guard sort of setup ideally)
Eventually I'll find a replacement crank and I'll play around between chainrings. I can't decide whether to go Robin's double 32T style route, or pyze guy's equal total number of teeth style. Either way, I already have a 16T cog, so I would imagine 36x16 and 34x18 would be a good range to start in. Whatever unramped chainrings are cheap and available really.
I'll be using an SS specific chain tensioner so I'm not sure how much lateral play I can manage.
