Hi all,

this is probably a stupid question that has been answered many times, but I can't find that answer, so here goes.

I need to know what size seatpost I should be looking for.
I have a 1999 Marin Indian Fire Trail frame, the seat tube is 34.9mm o/d and 30mm i/d. What size seatpost would be best suited to this? Should I be looking for a 30mm dia seatpost or perhaps a 29.8mm? Ideally I'd like to find something carbon, were they manufactured in these sizes?

All help and advice greatly appreciated.

Edd

30.0mm or shim to whatever size you want, probably 27.2mm. There's not much available in 30.0mm from memory
