davidtaylforth - Looks very good, didnt fancy reaming the seat tube on yours then?
jedi - nah i was told it would be sketchy for my riding
Is this a realistic possibility?
I have an iron horse mk3 with 30.0 seat tube and the options of adjustable seatposts is way more at 30.9

18bikes can do it for you

0.9mm is a fairly large amount of metal to ream when your talking about a seat tube.

I know it is but i think the seat tube on the mk3 is pretty damn sturdy. I can't remember the measurements off hand but i have a feeling the OD of the seat tube is the same as some 30.9 ID tubes. If that makes any sense.
I'll fire off an email to 18bikes once i have all the measurements again and see what they say. Price of the job may make it a no go as i will have to factor in shipping the frame down to them too.

Can you remember off hand the OD of the seat tube on your current/old BR jedi?
I know i can always play it safe and get a 27.2 dropper and a shim, just that niggling thought in the back of my head won't go away.

34.9 outer diameter on a BR IIRC

No worries cheers for the heads up about 18bikes, enjoy the new BR it looks sweet.
Will you be having a Friday night build tread like mamadirt does?

34.9

EDIT: too slow.....
Just for comparison a lot of frames have a 34.9 OD / 30.9 ID seat tube. Most Santa Cruz for example, so reaming out shouldn't be a problem unless you're giving it a hard time.

That frame looks a giggle jedi. Post some pics when its done.

Thanks slowrider and jockhaggis, much appreciated.
If my frame has a larger seat tube OD than 34.9 i'll email 18bikes otherwise i'll just go down the route of a 27.2 and shim untill i can afford a new frame.
I don't do the same type of riding as jedi but being a bit of a clumsy hefer it'd probably be a safer bet.
Well maybe not if the santa cruz bike are ok with it?

Specialized frames also have a 30.9 id and 34.9 od.
Looking good Tony. Think I can see the shock clearance issues they were on about from that pic, hopefully it'll be ok though!
