OP Roller Build. What size is the seat post?

[vestaviascott]

I'm about to purchase a replacement seat post for my OP roller and I don't know the size of the seat post.

Anyone have the specs?

I thought they were all the same size?

Mine is 27.2mm x 350mm

I've seen some that are 31.6mm

Yours is probably around 27.2 x 300mm

You're right. I took the post off and the size is etched at the bottom.

Some are 25.?mm, I know I had to send one back I thought would work.
