Seat Post Search

[velomentary]

Hi - I'm trying to source a longer seat post for a Gazelle Cheetah (1970/80s) I think. I can't seem to find a post with the right diameter and wondered if any classic road bikes etc may use a similar diameter but with a longer post. The seat post tapers in at the bottom so I think the correct diameter seems to be 23.5 or 24 mm - I've attached a few pics. Thanks

The taper is a lead to make fitting the seat post easier. A cheap pair of vernier calipers will measure the round portion accurately enough.

As guinness has pointed out you'll need a pair of calipers to be accurate enough ...being roughly .5 mm out on a diameter is getting towards 2mm on a circumference....seat tube clamps don't like that! Measure the post at lots of different points and take an average and then measure the internal of seat tube then you'll know!

Thanks - I'll get a pair of vernier calipers to be certain. Thanks for the replies

A micrometer is also an alternative

Also make extraordinarily good tools of finger nail torture.....nice and slow drawn out application of pain.... Very finely measured too

I do like Mitutoyo stuff rather than Starrett

My vernier is Mitutoyo. Had it for years, none of this modern digital rubbish. Gets used most days for something.
