got these off my 86 performer i purchased a while back. the bike was built up as nos and im pretty sure these are as i cant find a scuff, chip or scratch any where and they run true, there is some ingrained dirt here and there but nothing a good clean wouldnt cure.What i need to know is , is the front a metal hub
and the rear an alloy hub
and also the front is lighter than the rear .There are some lighter patches on rear, Is the front lighter because there were different yellows on metal hubs and alloy hubs? or is this age and fade. Cheers Carl
