Kastan Pro Full Cro-Mo

[Gnarlyscoots]

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 

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

 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..)

[Gnarlyscoots]

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

Sweet,sweet frame Tel 


Love owt Kastan, the uni blade fork and hub set up  with the 4 piece bars is just mentally cool 


I'll be keeping an eye on this 

[nic968]

 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..

[oldtired]

so it was the frame that was machined for the different headset cups ........ cool  i thought the headset race and machining on the forks was where the adaption was made ,    learn somat new every day    only saw one bit90's and that was well battered by a Barnsley street monkey 
 

defo with Dubber though looking forward to seeing this one

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 

Nice frame

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 

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

Really nice that is Bru 

[Bru]

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!

Bru 

[oldtired]

nice that 


bars are easy kastan 4 piece      there's a set of Mosh cranks on ebay at the mo with a kastan spindle 

[Gnarlyscoots]

Seat clamp. Will get just a sympathetic clean 

[Gnarlyscoots]

Seat clamp cleaned up a little and going to go with the DX brake. I also have the matching lever, lefty too

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 

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 

[Dark Diggler]

Road bike 1" headset cups are 30mm

[Dark Diggler]

Std cup 1 1/8 headsets are 34mm at insertion point

[Gnarlyscoots]

Thanks Si. Would you know where I can get some shims, 1 1/8 to 32.7mm

[Dark Diggler]

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

[Dark Diggler]

Or might you be better with an 1 1/8 fork?

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 

[Dark Diggler]

What about these?
