well i gotta admit i,m stumped,i picked this bike up from the local tip shop for $10 simply because it seemed to have once been a decent set of wheels ,and i just cud,nt say no lol,it,s kinda small but it has sum interesting features, on the top of the forks there is a cast mark of a big C with a dove in it, yet on the downtube it has the name Macini (unfamiliar with me) it has a dia-com stem and sidepull brakes an italia seat and suntour downtube shift levers and suntour f/derailer the rear derailer is missing, the wheels are a set pair with the front being flanged and the rear has no dork disc they r both steel,forks r fully chromed under paint , has welded brake cable lugs on top crosstube,bike seems very light 2 me so am assuming 531 renolds ? must admit i am not an expert lol,the Macini decals look aftermarket 2 me so maybe someone was trying 2 cheat a little lol,wud luv 2 know if it is a macini and where it is from , in fact any info at all , i will be eternally grateful,am hoping t-mar hears my plea ! lol
