Fork crown race too big

well, I got a cheap fork and it seems that it was filed where the crown race should stay.

how stupid is it to glue the race? I don't think there'd be a problem since it will all be compressed by the headset but I'm not even sure how I would glue it!

any help??

thanks!

dont do it

how loose is the crown race when you put it on the fork?

First of all is you fork got an alloy steerer or Steel?

If Steel, you can either send it to a frame and fork specialist and they put brass around the bottom of the steerer and then ream it, this may mean a re-spray. 2nd option is get a sharp but broad centre punch and 'BOP' all around the race area (cheapest option)

If alloy, is it really loose that when you turn the fork upside down it falls off?....... get an alloy can (coke etc) and cut a very thin piece and glue that on maybe then press your race on!

DONT GLUE IT! GLUE WILL BREAK DOWN AND WILL COME LOOSE AFTER A SHORT PERIOD OF TIME! :)

how loose is it?

is the fork 1" or 1 1/8"?

is your headset 1" or 1 1/8"?

someone else take it from here.

well, ok. here are the missing pieces of the puzzle:

1 - it's 1" and the headset is 1"

2 - not sure about what its made of: the fork is carbon and incredibly light so I'd say the tube is alloy. it's threaded though, don't know if it makes a diference

3 - yes, I have a few campagnolo and cheap races and they all fall when I turn the fork upside down

I thought about dripping some solder (?) and make the or glue it with some epoxy resin/glue. the coke can solution sounds good too

I'm not sure what you mean by this: "2nd option is get a sharp but broad centre punch and 'BOP' all around the race area (cheapest option)"

well, it is carbon and incredibly light then maybe its alloy steerer but with threads? i have not seen any carbon forks with alloy threaded steerers? maybe the numpty who filed the crown area threaded them? post a picture and that will indicate between alloy and carbon! but coke can is a very good solution!

and regards the centre pop! get a sharp pointed object, also an hammer, and hit the sharp object so it splages the material (column) there this will make the outside diameter slighly larger and help grip the race

this is a centre punch http://ecx.images-amazon.com/images/I/31YVGQE0RHL._SL500_AA280_.jpg

I think you're right, the steer tube seems to have been changed. it seems like an extra bit was welded in and that's the threaded part! can't I use the center punch on a alloy tube? I would give it a try, although the coke can seems easier. I'm just afraid the race will rotate

you can use it on alloy but with alloy being soft your not really gaining anything unlike steel! also the all crown maybe bonded to the carbon! try the coke can! maybe start off with 1 thin strand then work your way up until you get a nice fit!

i doubt there has been a bit welded on just how the fork was made? maybe post a picture of the column?

let us know how you get on!

here it is! it seems like the race had some solder on top. but I got it with a loose race. I'll try the coke can tomorrow and post results and better pics

^can I use pepsi?

use ginger beer if you like it :)

it does look like an alloy steerer but a better pic and a cleaner column may help ;) steel columns do tend to be more weighty than alloy of course!

I still I'll just use the first can I find. if that doesn't work, I'll choose a special one.

I'll post better pics soon, with the can trick in process

If a magnet sticks to the steerer it is steel, if not ally. My guess is it is an alloy steerer - but it looks a bit fooked in the pic. You can pick up good condition carbon forks for about £30 second hand so my choice would be to buy a new fork. Safety first an all.

I don't have a magnet! I'll get one tomorrow, thanks.

I wanna solve this, I like puzzles and this is the new one ;)

here are some new pics:

its does look like alloy but try the magnet trick :)

ok, got a magnet and found that it was in fact alloy and then some threaded steel tube was added

so, since the bottom part, where the race would go, is alloy I'll have to use the can thing. I'll do it as soon as my new headset arrives

there are different sized races for 1 inch headsets and forks.

yes but they all have to be a 1" race!

I have no doubts that the fork was filed. I compared it will several other forks, both threaded and threadless and they all have almost a 1mm extra where the race should go

my new headset will get here tomorrow so then I'll post pics with the new race and coke can shim

coooool :) what headset you gone for then?

I got a chris king on ebay really cheap, which I immediately sold to a 'friend' with a big profit...ahahah

I got lucky again and got an ambrosio on sjs, all black (without the ugly lettering) which will hopefuly get here tomorrow

you sure you have enough stack height :D ?
