whats up everyone.. this is my first post here.. im new to the whole single speed/fixie scene. i just picked up a frame for free and the guy told me it was a miyata frame or a sakai frame not sure the difference. anyways i have searched for a miyata and sakai serial number data base. but no luck. so i figure now ill ask everyone here

the frame is a 53cm frame and the serial number

reads: Y0L8133

if anyone knows what make the bike is by the serial number let me know
thanks
