I am having a hard time finding a 22mm seatpost.

Here is my dilemma:

I found an old school 26" BMX frame, that was obviously custom made in the late 70's/early 80's. The seatpost tube measures exactly 22mm.

Here are the seatpost diameters that do not fit- 22.2mm, 7/8", and 13/16".

What I am looking for is a 22mm, based on my micrometer reading, seatpost. Does this exist, before I start the machining process either on an existing seatpost or the seatpost tube?

Thanks for any info.
 
Bring it to a bike shop and have them hone it out a little.

Are you sure the clamp area isn't just pinched a little?

Got any pictures of the frame? :shock:

Well since you asked, here is the unidentifiable beast I am trying to fit a seatpost to. I have posted this here before, and no one on any BMX site is able to ID it:

it should be a 7/8 post, try spreading the slot under the clamp with a big screwdriver and I bet a 7/8 post slides right in.. :roll:
 
Awesome looking frame!! :)

I am having a problem finding a seatpost for my Murray cruiser. I have the old one & want to replace it, but it measures 20.1mm. I've checked just about every LBS with no luck. I was thinking about having some aluminum round stock machined down.
 
The very first 3/4 of the seatpost tube takes a 7/8" or a 22mm, but after that, it is very tight to a point of no more movement. I even have taken a hone that is used to hone out old school auto drum brake cylinders, and honed out the seatpost tube to no avail.

is it possible thats a homemade frame? it sure looks plenty stout! 8)
 
Genius! Why didn't I think of that? I was too wrapped up in trying to decide on where and how to make a new post. I think I may have to go this route. Thanks.
:D

If it were me, I think I'd run a 13/16" post with a shim to 7/8 at the top.
 
That's a sweet frame! I have no idea what it would be but looks like whoever made it knew what they were doing.
