Hello guys. Because i cannot afford to buy chain and sprockets for my bike, im looking for anybody that can help anyhow. I need my bike to got to work from cambridge to haverhill. My front sprocket is already missing 4 teeth and the chain is so loose that i cant tension that anymore. Has anybody got anything to spare? Could be used as long as it is in usable condition. Any kind of help and/or comments i would highly appreciate . Thank you!
