I exchanged the front/rear sprocket when I converted the drive chain to 530.
I think SUNSTAR is one of the most reliable brands. I referred to the secondary speed reduction ratio chart on the manufacturer's website, and chose 17T for the front and 46T for the rear to make it more close to the normal speed reduction ratio.
Compared to the 630 chain, the handling became lighter and the movement became smoother.
Looks like you access from European region.
Would you shop at webike.eu.com?
