Playing around with an older (2011?) Specialized Rockhopper frame I got for £25 back in February. An old 31.6mm post wouldn't fit, so I've bought a cheap 30.9 one - which seems loose on a test insertion (haven't clamped it in place yet). Anyone know offhand what the diameter spec is likely to have been?

Specialized are pretty much all 30.9. it'd be odd if yours isn't
