I have a dumb question, where do you measure for the BCD measurement for chairings? I want to order a bashguard for my Shimano STX-RC cranks and I am not sure what size I need to order. It is 5 bolt but not sure if I need 94mm or 110mm. if anyone can help me that would be great, auction ends tomorrow. Thanks!!
