Front sprocket

[brettLo]

just wondering what pitch and how many teeth is the standard front sprocket on a pitpro 140 ?

cheers

depends...but usually a 14 tooth. go bigger

some bikes use 420, some use 428....

i said it before somewhere, but...a 428 CHAIN will fit a 420 SPROCKET.
420 CHAIN will NOT fit a 428 SPROCKET.

428 is a little bit wider than 420. same pitch and roller size though
