I have a 1970's Motobecane bicycle with 27x1 tires. I need new tires and tubes. What would be the best size to fit, as I cannot find an exact match?

  • Are the tires tubular or clincher? – ojs Aug 24 '19 at 14:50
  • I would suggest you buy 27x1 tires. It may be that the best local retailers have is 27x7/8 or 27x1-1/8, but those should be fine. – Daniel R Hicks Aug 24 '19 at 17:02
