The Crupi "Chromoly" BMX Race Cog is made for BMX racing: in 4130 chromoly it is durable and strong enough for gate starts. It fits any Shimano standard freehub body and runs with 3/32" chains.
The base can be flipped: it has 1mm of spacing on one side and 2.2mm on the other. This lets you set the chain line as straight as possible.
