Any of you freaks ride single-speeds or fixies, or otherwise spin wrenches on bikes?
I'm having some chainline issues on my Surly ghetto 'crosser. The chain keeps snaking off when I least expect it, leaving me to either nut myself or unclip in a hurry and drag my feet to a skittering, spark-flying halt.
I swear I've got everything lined up right, but at least once per ride the chain will pop off. The setup has been bombproof until now.
Chainring looks straight, chain looks OK...anything I'm missing, besides maybe the concept of taking this to a bike forum?
