Help find 27,5 fork for 1 1/8 frame

capi

Hi to all,
I have recently managed to buy a nos carbon frame and I cannot find anywhere a fork that fits.
I need a straight 1 1/8 steerer fork who can accept 27,5 wheels (don't mind if the fork is a native 26" one as long as it has clearance for the 650b wheels) with travel in the range of 120 to 140mm and qr15 axle.
I cannot find anything suitable and available to buy in europe until now.
I heard that all 26" fox forks fits 27,5" wheels, is it true?
Any idea or advice?

Thank you very much,
Max

Those were just the first 2 I thought of (French stores always seem to be good for slightly obscure sizes).

Edit: sorry, the steerers are wrong in the alltricks one.

Fox 26" forks have a lot of arch clearance - typically just over 1" on a 2.25" tyre, which will leave 1/2" clearance to a '27.5" (27") 2.25 tyre, what tyre size are you thinking of running?

When you say it's a 1 1/8" frame, is that external cup or semi-integrated? The ZS44 standard headtube can take an external cup for a tapered fork.

Thank you for the suggestions!
I tried to put an external cup and insert a tapered fork but inside the frame there is an alluminium flange that does not let the fork to insert properly, there is 1cm of light, it's not usable that way.
Sorry for my english but I hope to have explained what I mean.

Is that metal structural? If not it may be possible to machine it out, also some tapered forks have a shorter length at the larger diameter than others, so where some won't fit, others may.

capi

I don't think it's structural but it is glued to the carbon so I don't know how to properly remove it and also I don't know if the heat caused by a driller to try to enlarge the hole could damage the carbon of the frame.

Probably the bonded in cups to take the headset, can be machined perfectly safely as long as you don't go crazy and produce too much heat.
