Looking for some rigid forks that are 120/130mm suspension corrected. I make that around 500-510mm axle to crown.
Everything seems to be around the 480mm mark.
Ideally boost and tapered steerer.
Other than some mega expensive Trek ones I'm struggling to find much.
Bird blank forks?
Karate Monkey/Krampus steel fork, which is 521mm and boost?
I know it’s the other way in terms of longer, as the KM can work with a 130-140mm suspension fork.
Edit: looks to be a mismatch on the KM bike listing and separate Krampus fork. Will need to check with a tape measure to be sure.
I thought the krampus fork was 48something.
Pretty sure the old kinesis IX carbon forks were sold as 120 replacements at 490mm so there might be a bit if a range?
Can't seem to find the Bird forks on their website, all links go to an Oops page, so guessing they don't do them anymore?
Krampus/Karate Monkey forks are listed a 483mm so unless there's a version I haven't seen I think they'll be too short.
Boost tapered 490mm? https://www.carboncycles.cc/?s=0&c=103&p=1897&tb=001
Or is that still too short for you (are you taking into account sag?)

Says 521mm fork length on the KM geometry listing when I checked, Krampus is 483mm listed and meant to be the same fork 🤷♂️
I don’t know which is right unfortunately.
I got one of these…

500mm a-c, which is similar to my sagged 120mm sus fork
Yes I'm taking sag into account.Current forks are 537.5mm axle to crown and 130mm travel, so 25% of that is 32.5mm giving me an ideal rigid axle to crown of 505mm.
Doesn't seem to be much out there as most bikes that have a rigid fork option appear to have a longer head tube to account for a shorter rigid fork.
Was just hoping there was something that wasn't eye wateringly expensive to have a play about with.
I've got a pair of Bird Blank forks i need to sell on. Message me if you want pics etc.
Have dropped you a pm
I got one of these…
Sonder Pathfinder
500mm a-c, which is similar to my sagged 120mm sus fork
Also the similar Planet X version. No cage mounts but also 500mm and somewhat cheaper.
Ah I managed to track down some genesis tarn carbon forks and they 515mm and boost.
Really great forks.
Came here to suggest forks from genesis tarn if you can find any
Selcof carbon forks have 510mm a to c, boost spacing and Tapered Steerer.
Thanks all for the help. Have gone with a set of the Bird black forks that I've been offered
As someone looking for a “normal” 485 rigid fork it actually feels harder to find than long ones nowadays. All newer model forks seem to be made longer when they switched to BOOST (eg Whisky 483 > 500).
Trek 1120 at 510mm AC is a good value fork for anyone else looking.
I also always point people to this page for inspiration on rigid forks and brands to look for:

I have popped a pair of these into my mates Decade Virtue 26" hardtail frame with a 27.5" wheel. Sets the head angle at around 68.5" and rides like it used to on 120mm 26" forks. Wheel and tyre size can be changed to tweak further.
If anyone else has some bird blank forks they want shifting I could be interested...

I run these on my on one scandal. I'm seriously considering the trek 1120 fork for the cargo mounts and maybe the front mech.
Other than some mega expensive Trek ones I’m struggling to find much.
For a branded fork with cargo mounts and a rack mount I think it's pretty good value at £350 ish. The sonder pathfinder is £339. If your not bothered about cargo mounts then the Selcof fork at £179 is a good deal. Just wait for a 20% off everything code.
After that, for a carbon fork it gets pricey, whiskey forks for example are £££
Its cheaper to buy a new frame and fork
