possible group buy, seatpost gauge set

Posted on
  • I had this idea before, buying plain 300mm kalloy seatposts(traditional with no clamp) in
    25mm,
    25.4,
    25.8,
    26.2,
    26.6,
    27mm

    they cost around $5 each(last time I checked) and can be cut into 3x100mm sections. postage is reasonable, ordered from the retailer before (USA)

    any interest?

    good to have for old frames

  • checked again, $6 each, 300mm

  • I bought an old unbranded 1970s bike, came with a 25.4mm seatpost which was the wrong size. I measured seat tube with digital calipers. 25.8
    bought 25.8mm, didnt fit

    already have 26.2mm and that doesnt go into the frame.

    recently got an MBK which came with a 26mm seatpost. tried it with the old frame, perfectl fit

    calipers dont give a clear reading for seatpost sizes for a few different reasons
