Seat post Clamp size for Ferrous 29er

[Steel29er]

Anybody know what size clamp I would need for a 2009 XL (steel) Ferrous 29er? Looking to get a Hope bolt on. Currently have a Thompson 27.2 post, bought a hope 28.6, but it is too small...thinking 30.0???

31.8 is the size you are looking for....

Very common size, you should have a bunch of options....

Thanks Lew, appreciate the help.

No worries, a 32 would work as well if that helps your potential bling options...
