Just popped my forks out to take about 15-20mm off the steerer.

It seems there's an insert already in place, am I ok to cut through this?

I haven't seen this arrangement before so not really certain how it works or specifically how much length is required on the insert.

Any pointers?

Ta

e2a "road" in the title, in keeping with current trends 😉

Insert? Sounds like that might be the equivalent of the star fangled nut in the carbon tube.

It should come out, see if there's an allen key fitting in there where the thread for the top cap goes through. It should unscrew and slacken off though from experience they can be a bit of a clart to get out.

Technically you could cut thru it, but you'll be needing to buy a new one to replace it if it is what I think it is.

A star-fangled equivalent it is, but anyhow it's unscrewed and left a sleeve inside the steerer.

I'm guessing this may be glued in or something otherwise it would slide up when tightening the top cap.

So I'm left wondering how much length I can afford to lose off this sleeve before it gives me grief...

It might not be, there might be a o-ring around it and once the SFN type thingy opens enough it'll grip the rough carbon. If you look down the steerer is there a cut going down the length of it that might imply it's just held with tension on the sleeve?

Can't believe a fork maker would effectively make a fork uncuttable by doing that.

No worries, I've managed to get the sleeve out. Seems it's just knurled rather than glued and uses a wedge shaped nut to expand it outwards...
