Cranks for Surly Cross Check

Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer?

Cranks for Surly Cross Check

I'm looking for some cranks for my cross check. For now, I'll be running it single speed, but would like to run geared in the future.. Though, if I did run geared, I'd only run a single chainring.

I already have an IRO crankset.. I'm sure I'll have no problems running the cross check single speed, but would I need to change out the crankset if I put a 9 speed in the rear?

figure out if your chainring is intended for multi-speed 1 1/32" chains or fat 1/8" (bmx) chains.

1/8" chainring teeth are too wide / thick to run multi speed chains. but you can go the other way-- bmx /ss chain on 1 1/32" chainrings without problem.

With the IRO recommended 68*110 bb, the IRO crankset will put your ring at 42 mm. This could be a little noisy/ cross chainy when you're on the smallest cog in back, but it will probably work OK and if its too annoying you can always put in a bb with a slightly longer spindle, say 115.

Something to consider, 135 or 130mm on the rear axle.
This is Africa, 1943. War spits out its violence overhead and the sandy graveyard swallows it up. Her name is King Nine, B-25, medium bomber, Twelfth Air Force. On a hot, still morning she took off from Tunisia to bomb the southern tip of Italy. An errant piece of flak tore a hole in a wing tank and, like a wounded bird, this is where she landed, not to return on this day, or any other day.
