KXL 47T 53T 56T Alloy Folding Bike Crank Set With protective Cover Road Track Bicycle Chainset 170mm Crank 130PCD

Super lightweight 56T Crank Set, easily fitted once I had removed the original set (48T) on my new 20" folding bike using the Draper 31039 crank removal tool. I measured my existing chain and found that I did not need to replace it with a longer one using a formula that I found on line. Measure the distance in inches between the centre of the bottom bracket and the centre of the back axle. Multiply this distance by 2. Then divide the chain wheel teeth by 4 and the largest rear cog teeth by 4 and add the 3 values together and add 1, This gives you an answer in inches. Mine was 31.5 + 14 + 8.5 +1 = 55. Each chain link is 1/2 inch so this resulted in 110 links which was the exact measurement of my existing chain.Draper 31039 Bicycle Crank Puller

Bought for my 20inch wheeled electric bike, to replace a 48t chain set. This one at 56t gives a much better top gear. It has a good solid chain guard, helps protect trousers and will help prevent the chain jumping off. Perfect for any 20inch electric (or non electric) bike.
