My chain snapped ,need help My chain broke today and I want to get a new replacement for it I just don't know what size I need my bike has 3 gears in front and 6 in the back which I'm guessing is an 18 speed and if you can leave any suggestions for a chain I will appreciate it preferably under $30 I just commute to school.
You should get to the bike shop and they get you a chain the size you need. If you don't want to go with you bike, take your older chain. For sure it is under 30$. I paid less than 20 for a SRAM chain not long ago.
