Would a double clamp or hinged not do the trick

$:-\$

too big or small? i have some clamps that are different sizes by small amounts.

I've got one of those Pete, the one you grappled over the fence at mk. I built the tube up with electrical tape and got a dc hinged on it, that works fine. If not you could try a cut down seat shim on the outside

When I had one many moons back, I am sure a had a 'tange sc-2' on it...

Would an early road bike one fit ? , kinda like Campy/Suntour/Shimano .............

Ask Steve Earl what he has on his chubby

pete rickman made a shim to fit over seat tube which made up the difference
on seat clamp it was just a bit of tube with a slit in it or take a look on ebay
for a dk split seat clamp made for minis

The 1983 Gt mini in BMXMUSEUM has an Dia mx hinged job!

Not sure if its tight or not....

Hold tight, I remember I bought another GT mini years ago with a clamp fitted, it had a split shim fitted inside. Fook knows if I've still got it but I'll go digging....

*UPDATE - Not found it

It may turn up , my junk room is sky high with unorganised crap. Found 4 mx 1000's, dx's, boxed forklifter stem, a burnished ripper among a ton of other bits....not a bad rummage.

found them, there are these tange clamps that are too small for a normal bmx. they measure a little over 20mm inside. one was shoehorned onto a showpony the other is lightly used.
nice blue clamps. LMK if your interested
