The regulation of NJS is "42mm±2mm from center of frame to the center of chainring."

To quickly ensure for it, you just need to put the guage on the seat post. Aline the V-groove protrusion to the frame's center, check if your chain is in the the black thick line.

 

It mades by hairline stainless steel which supports the sense of parallelism and right angles when working.

The burrs on the product are removed by hand, leaving some edges possible to do further machining.

 

*Please be careful not to rub your bike tube with the cross section of the V groove.*
