When you're hitting the sort of leg speeds modern day BMX tracks demand, you want the reassurance that your chainring will run true lap after lap. The Box Components Cosine 4-Bolt Chainring is made in the USA from durable 6061 aluminium with large square shaped cutouts around the perimeter to help save weight, 3/32" teeth with rounded tooth profile to reduce chain wear, laser-etched BOX logos and a 4x104mm bolt pattern.
