{"product_id":"7-speed-screw-on-freewheel-14-28t","title":"7-Speed Screw-On Freewheel, 14-28T","description":"\u003cp\u003eA chain that skips under load, a wobbly sprocket stack or a seized freewheel body all mean the rear freewheel is worn out. This screw-on 7-speed freewheel has 14-28 tooth sprockets in high-tensile steel, and it comes lubricated. The manufacturer lists it as model MF-TZ500-7 and says it fits a standard threaded bicycle rear hub.\u003c\/p\u003e\u003cp\u003eListed uses include mountain, BMX, e-bike, hybrid, fat bike and cruiser bikes. The listing does not give the thread size, so confirm the thread type before you order.\u003c\/p\u003e\u003cp\u003eCheck before you order: this is a screw-on freewheel that threads onto the hub. It is not for cassette (freehub) wheels, where the sprockets slide onto a splined body. Count your sprockets (7), note your smallest and largest tooth count, and photograph the face of the old freewheel. Removing the old freewheel needs a matching freewheel remover, and the listing does not say which remover type this freewheel uses.\u003c\/p\u003e\u003cp\u003eClean and grease the hub threads, thread the freewheel on by hand until it seats, then refit the chain; a 7-speed chain and a 7-speed shifter are needed.\u003c\/p\u003e\u003cp\u003eNot sure it fits?
