I was wondering how safe it is to ride with a loose chain. Mine is VERY loose right now. It sounds like it is rattling against the chain guard. I plan on doing both front and rear sprockets plus chain in the very near future. However, until I can scrounge up the cash I still want to ride. The rear axle is already adjusted all the way back. Anything I can do if this is a dangerous situation and I can't ride until I get the new stuff? Can I remove a link or two? Would I need a special tool to do this if I can? Also, when I do finally replace the sprockets and chain is there anything else that I should particularly look at?
