Terry I have one of these with the forks.... I'm 99% the forks are 1" non-threaded

The head has skims to take and 1" headset or without it will take 1" 1/8, I think that was the case but I will check tomorrow.

Bru  :daumenhoch:
Thanks Bru. If that is the case, could I not just buy a 1 1/8 threaded headset? Would that fit a 1" fork?

Sounds dumb but new to this malarky  :D   ;D

 You may have one of the frames that took a 1" cup at the top and a 1 1/8" at the bottom...Sounds weird, but Kastan did make some 'transition' frames and forks that took a regular shafted stem on top, yet had a thicker crown I think..
 Did you check top and bottom measurements? If they're the same, it maybe 1 1/8" all the way, which could work out easier in the long run..( Apart from the GT forks..)

I have just measured the interior diameter of the top and bottom of the head tube and it comes to 33.5/34mm. Is that 1 1/8?

If so, Jon has found some reducer shims on the bay which will enable to carry on as planned  :daumenhoch:

 If they're both the same, and too baggy for the beartrap, then it's a 1 1/8" frame..You could use 1" threaded forks using a regular headset with shims if your set on using 1" threaded forks..
 I went through the same thing last year after being sold a 1 1/8" frame as a 1", but I've opted for the 1 1/8 route.. :)

No and Yes

1 1/8" = 28.6mm but 34mm is the correct head tube inner diameter for a 1 1/8" threadless set up.

Minor set back  :daumenhoch:

Nice frame   :coolsmiley:

Shims ordered buddy and I will be using my genuine BT II for now. I'm going to try and track down an Odyssey Pro headset but not at the stupid money like the one on US Ebay  :D

These are my fork options. Going with the GT because the Eagle claw drops and the welding is superb  :daumenhoch:

Ta  :)

Need to get my ass in gear and finish it, not 100% sure about the bars... Don't know what tyres to put on it, what brake would be right, what lever and grips to use  :-\ 

Never had so many issues before!

Terry,
Have a look at this article about Winnie Wright RIP. He was riding a Kastan in the mid 90's before he had the Pashley.

Right guys. I got hassle here  :yahoo_silent:

My head tube inside diameter is 34mm (give or take),

a standard headset cup for 1" fork is 32.7mm.

I fitted these shims and tried to fit the headset but it wouldn't, so I measured the inside diameter of the shim and it is 30mm (give or take).

Is a 'mini' headset cup 30mm ??? If so, then that is what these shims are for and I am back to the drawing board  :(

Once you have the right headset,It's the steerer that needs a shim isn't it, 1" - 1 1/8"?

http://www.evanscycles.com/products/m-part/threadless-stem-shim-adapter-ec039894?country=GB&currency=GBP&utm_content=mkwid__pcrid_17321847296_kword__match__plid_&gclid=CN_83qTD7rsCFc3KtAodex4ApQ
No, that's going the other way round. I need to reduce my 34mm headtube to accept a 32.7mm headset cup. Maybe a Uni seat post shim would do the trick? It needs to be approx .5mm to 1mm thick.

My mate in the US has the headset that came off this frame but the lower cup has a crack in it.

As I have already bought the fork, headset and stem for this, I didn't want to go down the route of having to buy more and try and sell what I have, if that makes sense  :-\
