Whats the largest chainring you can run with a straight chainline on a surly 1x1

wow, nobody knows...

Does Surly know?

I am uncertain as to whether or not this is a definitive answer, but I have a 34T on mine and it is tight. My guess is that 36T would be the absolute max, but this is speculation at best.

I have a 38T on mine(cant wait to get rid of it though, kinda limits ratio choices below 2:1. Plus i want eno cranks). Anyway, there isnt to much extra room in there, im thinking im just about at the limit.

BB width should be worth considering, too.

BB spindle length shouldn't make a difference as it will modulate chainline when modified, i.e. if your chainline is spot on with the rear hub, your chainring clearance is finite. You can run the chainline slightly off, but this tends to make noise and reduce the life of your drivetrain (often shaves the tooth to a smaller thickness).

...and rear wheel/chainline. Say you're running a converted cassette wheel with the cogs all the way outboard and the chainring on the outer position or BB with a long spindle. Surely you can use a bigger chainring than if you were using a SS-specific hub and single FW with a "standard" chainline.

That's a good call.

Depends on the hub used, too.

Im going to be running it with surly hubs, which means 52mm chainline. Im just trying to get a good gear ratio, because im also gonna put some 1.50 tires on it for my coummute and then bigger tires for actuall trail riding. I guess i could keep a 38t with a 16 freewheel for trail riding and a 14t track cog for fixed commuting.
