Hi
In the process of bringing a Mongoose Cali back to life. Just purchased a Tangeseiki headset but cannot get the bottom headset over the threaded forks. The headset does not have a thread so assumed would slip straight over. Have I bought the wrong headset or are my forks the wrong ones that were originally on this bike?
Any suggestions would be greatly appreciated.

Put some pictures up as it doesn't sound right?

Is it only a cats whisker off going on or quite a margin. If the former, sit the ring on a hot plate or stove so it expands slightly then seat it square and tap down with a long section of tube which either matches the diameter of the inner section of ring or the outer. Dont hit it around the bearing curved section... if that makes sense :daumenhoch:

That's the bearing race that fits onto the bottom of the stearer tube. It doesn't screw on... it needs tw@ting on with a hammer. :daumenhoch:
I use this (http://i1164.photobucket.com/albums/q565/CustardLips/IMAG0225.jpg) (http://s1164.photobucket.com/user/CustardLips/media/IMAG0225.jpg.html)
A piece of (I think it's 25mm ) copper pipe and keep belting it till it's on. :daumenhoch:
Oh, put a bit of grease or vaseline around the raised part of the tube to ease it in/on... you know the score. ;)

The hot plate/stove is a good idea too... put some fookin gloves on tho. :shocked: :LolLolLolLol:

Cheers guys, I will give it a go. :)

I'd turn it upside down then put wood on the bottom of the steer tube and twat that so the copper tube is against the ground, doing it the way it is in the photo runs the risk of damaging the fork drop outs :daumenhoch: if that makes any sense :LolLolLolLol:

Looks like your forks have been rechromed? ???
If this is the case, then you'll struggle. :-\

There are two sizes of crown race 26.4mm and 27mm.

I had a set of forks recently that were 27mm although it's only .6mm if that's what it is that crown race will never fit.

Fookin hell mate it's not a square peg in a round hole and usually doesnt take much tw@ting to get on. Put the timber under the dropouts whilst belting the other end with your best Franz. Cr-Mo v's 3×2... there's only gonna be one winner. Done this many times without any damage to any forks I have abused in this way. :D

I use a file and/or a dremmel to shave a bit of the forks. Each to their own. Whatever works for you is good :daumenhoch:

Cheers Guys
Took all advice, filed down slightly, heated up and put metal tube over and banged it one. Lovely!
