I hate to change the tune...I have a 75 paramount. I think it came with a track fork or someone installed a period correct paramount track fork. I have 700 c wheels, ma 40 with record hubs. What is the largest tire I can fit? I am 220, and wuold love to have 28mm. I almost bought 25 mm assuming they will fit, and then I figured might as well ask the professionals. With so much knowledge about brake reach and period correct rim size... someone has to know what is the fattest monster I can throw on a 75. She was repainted by cycle art. I am going to "murder" her out. I have a all black campy triple (mirage) and I have a black stem and I will throw on some bar end shifters. someone also added the cable guides and screwed in a cable guide on bottom of bb. Also, I do not know what model it is. I tried posting more pics and they it is not letting me. anyway, good luck with the build. I think the pasela 27 1 1/4 will fit.
