Well, it's better than an over-short steerer!

Okay, I have a need to lop a fair amount off my steerer - alloy, atop a CF fork. The SF nut is already in there, will need to be lowered to match the new length.

Am loathe to buy the Park tool to screw into the SFN to hammer it down the steerer as I'll not use it all that often - as in, maybe this once.

Anyone got any proven ideas for re-positioning the SFN without laying out for the specialist tool please? I do all my own bike maintenance, can RTFM and understand the best end of a screwdriver to hold :)

The cop-out is a trip to a LBS, but I note that many of their mechs have sore knuckles from them scraping against the ground when walking...

All suggestions gratefully accepted. Thank you in advance

Regards

Dereck

Cut the steerer off to the top of the nut, thread in a long version of the appropriate bolt, tap in it further, cut some more, repeat until done.

I always set my SFNs with the bolt from the top cap. You just have to be careful to apply the tapping in a uniform manner to get it to go in straight.

I've never cared for the SFN except in steel stearers. I've always used expanders. If you want to keep it straight, you might use a longer bolt that matches the SFN threads.
It's better to make two or even three cuts than to cut a little too much.

Thank you for the ideas folks. Now, having never done this before - how much force do I have to use to drive the SFN downwards? Looking at it in its present location, it appears that it is a real tight fit down there, as I'd expect.

Light taps? Fair whacks? Don't force it - use a really big hammer instead!

Fortunately, have to go to a hardware store this PM. Have this idea involving a longer bolt and a couple of matching nuts locked together on it. Screw bolt into SFN until the nuts are sitting snugly onto it, then apply force with my little 'ammer.

Expanders - sounds logical, but can't say as I've ever come across one in a bike or a bike shop. I really have to do something, its a wart of a thing sticking up above the stem, covered in spacers.

Sometimes taps, sometimes wacks, Sometimes a really big hammer.
