Miyata Triplecross seatpost diameter



Just bought a Miyata triplecross frame ('92 or '93) on eBay to build
up as a touring/all-rounder.

The guy selling it says it uses a 26.4mm seatpost.

I checked the hallowed Sheldon Browns seatpost archive and it looks
like Miyatas of that era use 26.8

Anyone know for sure?

No, but are you sure you read Sheldon right? Koga Miyata Team frames
have a double butted seat tube, hence 26.8. The lesser models had
heavier material so 26.4 is not unreasonable.

i think your best solution is to make the seller include the seat post -
then it's his problem to be sure, not yours.

I worked on Miyatas of that era, and if memory serves me correct, the
ones I built up were all 26.8. Worse comes to worse, find a much more
common 26.8 mm post, and sand it down a bit; 0.4 mm is not a lot of
material to remove and shouldn't compromise safety if the post is of
decently thick aluminium.
