So if its 25.4, what size seat clamp should I buy also? Sorry for all the questions 

[HEYWOOD BMX]

28.6-standard bmx size.Just watch out for some of the superlight machined to death stuff,I `ve been through a few of these as there`s not enough material to take the stress when you tighten the bolt.
