Re:

I have just bought an old Kona which someone has removed a stuck post without a lot of care and it still wouldnt take a 27.2 post instead of the correct 27.0 so i would say wait for the right size

Alright, next inane seatpost question. Having trawled fleabay for 27.0mm seatposts, do I go for a fairly decent Easton aluminium one or a suspiciously cheap Kalloy Uno carbon fibre one? I'd like a carbon one but the choice in that seat tube size is somewhat limited.

Re:

Check the weights if that's important to you. Cheap carbon posts can weigh more than decent alloy posts

Well the alu one doesn't have its weight listed but given that this bit's in the description, I'm not sure the seller knows.

Husband said he paid a fortune for this item....

Oh and the carbon one's 249g apparently, which doesn't sound too bad to me.

Kalloy make seatpins for almost everyone, it's not likely to be a bad seat pin........

Which model easton?

 

[mattr]

And not sure she/he knows what a fortune is. The EA70 is only about 40-50 quid new..........

All I know it it's a black one

I think I might go for the carbon one actually if the make is decent.

How does anodising only slow down galvanic corrosion between carbon and aluminium?

 

[mattr]

Poor anodizing? Porous finish, scratches, salty water.......

A perfect (HA!) hard anodized finish would only be subject to the salty water (and it'd take far longer as it'd have no where to attack.)
