swingarms and axles shifting arent the main cause of chains coming off..
youre far more likely to break a front sprocket, which i have, or get a stick or rock caught up in there.
worn out chain sliders and rollers are far more likely to cause a chain to come off.
absolutely your chain should be adjusted properly, but bad bearings arent nearly as likely to cause a chain to come off.
whats with the name calling? youre a dick.. i just got a PM from some sissy saying youre an asshole.
