I am building a 200x from the frame and up. I bought a front tire from ebay but for some reason it wont fit my hub. Could it be that I have like a 86 hub or somthing and a 85 200x tire? The guy said hes positive it's a 85 200x tire. So i unno. If any are interested i'll post the pics of the tire..I just measured the hub and its 5 inches from one stud to the other (not crossing the wheel). The wheel I have is 5 3/8 apced apart. Help me out thanks!
