It is NOt in my opinion a 85. But an 84.
Look on the rear dropouts. It will NOT have gnurling. The 85 would.
Dont ask me how I know all this stuff, ok , its cause I found an unstickered Redline once and found no site to help me id it.
So I researched and made my own site lol.
http://redlinebmx.wordpress.comI havent put everything I know on the site yet cause I sold the bike and rarely update it , till I find another old Redline to motivate me lol.
