Replacment forks

[adds21]

Hi,

I need to replace my forks. My original forks (tapered) look like this at the point where they enter the frame at the bottom (I've removed the baring, obviously)

The only replacement I've so far managed to find looks like this:

So, my original forks have a flat section just at the point they enter the headset, (where the baring sit). Is there any way I can get the replacement forks to fit in my frame - I'm a little unsure as to where the barings would sit on the replacement fork, even if I could get it to fit using somekind of adaptor or something?

It's proving to be a bit of a pain, as I've had no luck sourcing a tapered fork with the same profit as the first image (from a 2012 Boardman CX, the lower image is from a 2015 (I think) Boardman CX). If I can't adapt the lower to fit the upper, does anyone know where I may be able to get a fork which fits?

Thanks,
Adam.

The top picture shows the crown race still on (that is the bit the bearing u removed sits on) - that will need to be removed and put on new forks

Bottom pic, no crown race fitted, but also looks damaged at that line an inch or so up from the crown race seat?!

Thanks for the info about the crown race. That's excellent news.

Do not use those forks in the bottom photo under any circumstances, until you have them assessed as ok by a competent bike shop.
They look seriously damaged to me.

Modern forks have a built-in crown race. In other words, you can use the bottom fork but you will not need the tapered ring that comes with the headset bearings.
Neither of them are damaged, it is the light and photos playing tricks.

I'm also pretty sure you only have to replace one fork, not many.

I don't know of any competent bike shops with x-ray equipment. You'd need an aircraft engineer or one of the few specialist CF repair businesses to have potential CF damage properly assessed (or a friend at Force India )

You don't need x-ray equipment to see the damage that seems to be present on these forks, but a competent bike shop will either immediately condemn them based on a visual inspection or advise where they can be further assessed and it if is financially worthwhile to do so.

They do not use xrays on cf - ultrasound is what is used. It is hard to tell from the pics what is what with the forks

Isn't that then same thing?

BTW, did I tell you why I got sacked from the pre-natal clinic...?
