Just got a set of on-one rigid carbon forks and the steerer tube appears to be just shy of 4mm thick all round, meaning I’ve only got a hole of 22mm – which means I can’t find any of my existing expanders in. Does anybody know of any brands that make small expander bolts at all that’ll fit the damn things ?

cheers

On One?

I wish – useless. Sold one to me that didn’t fit despite promises it would.

Insider diameter I assume, and you mean a star fangled nut?

OnOne? Its the £14.99 if you have a Fatty Carbon fork

Look for one that is specifically for a carbon fork. Should do the trick.

Ribble

Beware OnOne themselves do two carbon fork bungs – they are different sizes.

Plyphon: Inside diameter indeed – and not a star fangled nut, as you really don’t want to be putting one of those in a carbon steerer tube. It’s a compression/expander bolt.

igm: I’ll give that one a go, it’s different to what was sold to me, and different to any of my existing ones. It’s for the rigid 29er forks though, not the fattys

Woody: Yeah, I’ve got a pile of them here. None fit. By way of comparison the smallest diameter I can get my KCNC expander down to is 23.3mm, so just won’t go in

The £9.99 one is larger diameter, the &14.99 one is smaller.

nice, thanks very much – thats way more helpful than on-one were 🙂

Want to guess how I know…

You wouldn’t think something this simple would be so hard would you
