Ultimate Hardware 5/6/7 Speed Bike Chain - Great value replacement or upgrade Shimano compatible F50 cycle chain from Ultimate Warehouse, perfect for any geared bike with a 5/6 or 7 speed rear freewheel. Please note that when replacing a chain if your freewheel is really old or covered a lot of miles it may cause your new chain to jump under load, so bear in mind you may ultimately need to replace your freewheel as well.
