This is 59 drive links of full compliment, full chisel, race chain. I was looking through some old stuff and found this. It was done by Art Martin and is very fast. If you have never had a full race chain, this will surprise you. The teeth are back where Art felt they were the fastest. It takes some power to run this chain so don't expect it to be good on your homeowner saw. It is .063 gauge. $150
