Started to build my sons bike today and had nothing but trouble trying to fit cups. Dremmel helped in the end but the problem I now have is that the fork stem is to short. Or am I making a school boy error here, wrong headset ?
Head tube length: 103mm without cups
Fork stem: 127mm
Any suggestions ?

Looks to me like those forks have been cut down :-\
-
Your right norty, iv just spoke to a seller in America who has these forks and his are 5.25" and my fork stem is just over 5 " :'(
-
Yeah you can clearly see that...
Did you see them prior to purchase?!
-
^ no mate it was an eBay purchase.
Just put it together roughly to begin with and it looked long enough.

those forks pop up on the bay fairly regularly :daumenhoch:
-
^ if you see any and remember would you give me a shout.
Does anyone recognise the frame or know who owned ?
-
Can't you try the bottom bearings in the other way? You might get some extra length.
I know those headsets and it does make a difference.
-
yup looking at the pic on my phone of my pinched forks, they are cut down ::)
swazal may be your answer ;)
-
Good call, i have a threaded inch I cut from a Fork to use as a flex fighter bitd if you want it to weld on ?
-
Annoying that. >:(
How about a set of these from bankrupt bike parts on ebay? :-\ Very good value at £20.99 posted. :)

also: In the 2nd pic: things look as if they weren't fully engaged yet... ?
and in the 1st pic: .... it might be possible to get some extra lenght/threads for the locknut by grinding off a bit of the adjustable race (the 'washer'-looking thing at the top of the headset) ...?

Problem sorted :D
Headset fitted
