Please Note: You can check your chain length by simply counting the number of pins using a zip tie as a marker, remember to allow for sprocket size changes when going larger. You can "cut" a chain by grinding the two heads off one link and using a punch. Connecting a chain should be done by a professional using a chain riveting tool or with a clip type connecting link normally sold separately.
