A couple weeks ago I found an old gitane roadbike when i was helping a friend clean out his garage. He didn't know what to do with it so i offered to take it. The paint was worn and chipped and the tires were cracked, and so i thought it would be a good idea to fix it up with nicer components (seat, seatpost, BB, crank, new tires, new paint) and then convert it to a single speed.
I brought it home, took some measurement and found that the parts needed (diameters mainly) are smaller than anything i can find online. The opening for the BB was about 34 mm and the seapost is about 25 mm. Im more of a mountain biker so im not sure if these measurement are normal for a road bike. It may just be that standards have changed over the years.
Would this be a good bike to convert?
Any suggestion where to find components?
