Seriously! These are snow chains that fit around a rear mountain bike tire. It kicks butt people! You will not slip, slide or fall down! And if needed it'll make a great "stay away from my bike" weapon! But no don't really do that! Try it you'll love it!!! Made of rust proof stainless steel.
An older version of snow chains for mountain bike tires. Made by Monitor Traction devices. Weighs only 17 oz. for the pair. Easy to install. Will do both tires. Sold for 44.00.
