i bought a mid-new school torker at a pawn shop and i'm wondering about the cranks.they look like redline and have the redline sticker.the thing is,they are not stanped like my 401's.they have the indention on the front for the sticker,but are smooth on the back.single pinch and full wrap.there is no redline stamp and the length is on the back(inside)at the pedal.they are also about 1/4 inch wider at the spindel than my 401's or any other redline 3 pc. i have owned.any input?
