simonm:
Still not finished my Ammaco build, need a seatpost, looks like the sizes are 1"  Is a 1" seatpost, with a 1 1/8" clamp an old standard ? e.g. from 1985 ?

HEYWOOD BMX:
Sounds right to me-OS post=22.2mm needs a 25.4mm clamp.

moley:
Yep, measure your Seat Tube.

If its measures to 1" or 25.4mm then you'll need a 7/8" or 22.2m Seatpost and it will use a 1"  Seat Clamp.  :daumenhoch:

simonm:
nope its 1" inside diameter...

HEYWOOD BMX:
 1" inch post will need a 28.6 clamp.
