Single speed Mountain bike is currently running 34 x 16 , (26 " wheel)
I want to run 36 x 16
Chain rings will catch chainstays if fitted on inner of crank
If I fit 36" chainring to outer of crank it will upset the chainline.
Will this throw the chain?
Is it less efficient mechanically?
I don't want to use smaller sprocket, been advised 16T is minimum to use off road (Surly)
