Hi Guys! I/m New here and as well as in cycling. I got my first bike just recently and its a Bridgestone Roadman Super Colmo. Would anyone be kind enough to help me identify when this was made or any other info regarding my bike? I found very less info on google. its Serial Number is RM703s. i cant post any photo since the forum wont allow it yet. If you guys want to see it I can send it to you.

Thanks in advance! ​​​​​​

Welcome to the forums. The Roadman wasn't marketed in the USA, so you won't get many responses on the forum. It was marketed in Japan and Eastern Asia, possibly some other countries. That RM703S is on a sticker and isn't the serial number, which will be stamped somewhere on the frame. Many Japanese market frames have it stamped on the front of the head lugs.


The crankset is are quite distinctive but I don't recognize it, so it may be some Asian brand that wasn't popular in America. The rear derailleur looks like it may be a Bridgestone Klimatic. My overall impression is entry level, as I'm seeing exposed brake nuts and nutted hubs.


Fade paint jobs didn't start to become popular until the late 1980s, so that's probably the earliest possible date The crankset itself looks like it could be 1990s. If you can find the actual serial number, that will help. Also, assuming that is a Klimatic rear derailleur, they were manufactured by SunTour and the back of the parallelogram will have a date code consisting of two letters that should be within a year of the bicycle itself.

This bicycle looks like a Roadman Super Colmo model.

I have seen a Roadman Colmo model with the model sticker FMC703 F.

The crank set looks to be one of the late 80's Suntour models which would match the other components.
