    • 5 Bolt (130mm bcd) Chainrings

    A chainring with only 130mm bcd (bolt circle diameter) spacing is typically a vintage road bicycle standard. However, in the late 70's, road bicycle cranks were regularly used on BMX bikes as a lighter alternative to Ashtabula (one piece) cranks. 

    The most common BMX chainring bolt circle diameter is 110mm bcd, so be sure to measure carefully before ordering a 130mm bcd chainring.
