If anyone has a part number I'd love it if ya gave me a shout out
As so many are successfully running jack shafts and thus - their regular bike chain is taking all the drive load, I really think the oversize 41/415 is just plain unnecessary. In addition such a BMX chain is often available in far better quality than the kit supplied 415 or even a 41 picked up from a local hardware store.
Here's a link of the part number, MK918 Yaban Half Links BMX Chain. It claims to have a 1.5 ton breaking point. I'm using this on the shifter kit. However, this chain does stretch a lot.
