Hi Can you supply this product with a 63mm bore and does it fit a 530 chain? If so what would be the cost for shipping to the United Kindom Many thanks David
A: This should fit 530 chain. The dimensions between that and 50 pitch seem to be the same. We are unable to provide 63mm hub for this. The hub bore in the sprocket is only 2", so a hub would have to be fabricated, and this sprocket would have to be machined to accept any such hub.
