Disc Mount Forks for Pompino

Inspired by seeing Stephane Mehdi Ouaja finish the Transcontinental on his fixed/free Langster I've decided to dedicate my winter to riding fixed far more often. As a consequence I want to make use of my Pompino but also my lighting/dynamo set up from my own Transcon ride - a Kaffenback. To use the SP PD-8, Archetype front wheel I need a disc mount fork that'll fit the Pompino. I'd like steel, I'd like black, I'd like just the disc mount that'll take my BB7 caliper and not a disc/V combo. I'd consider carbon if need be but unlikely as my budget is next to nowt. I could of course use my Archetype wheel by taking off the rotor and using the Pomp's Condor canti but that'd spoil my rim's pristine brake track! Ideas??

surly disk forks are beefy and strong

I've got an unused Pompetamine fork that I bought for a project in the distant past, it meets most of your criteria as its disc only, steel and was built to match the Pompino geometry - £35 if you want it.

It is white, but a can of spray paint should solve that.

and you can customize (improve!) your headtube angle and trail.
pick one:
surly disc trucker 26" fork, Axle-to-crown: 376mm rake 45 max 700c tire size 37mm
surly straggler 650b fork, Axle-to-crown: 380mm rake 44
surly disc trucker 700c fork, Axle-to-crown: 390mm rake 45 max 700c tire size 50mm (guess)
surly straggler fork, Axle-to-crown: 400mm rake 44

Socialamnesia, thanks for the offer. The Pomp has black carbon ones at the mo but the frame is that sort of pearly white colour. If the forks are the same then it could work without a paint job. Just seen the price of a single BB7 caliper though!!

Could do you a deal on one of those too :)

OK, thanks again. I'll bear it in mind. The Transcontinental has left me bereft of both funds and brownie points at the moment and so it may be a little while before I get back to you.

Did you choose a fork in the end?

I'm tempted by a Surly fork myself but would dropouts angled forward on a disc fork. The other option discussed, the Pompetamine fork, is, I believe, only suitable for centre-lock style hubs.

Kona p2s are the same geo as the pomp fork. I run one on my Pompetamine. Loads of tyre clearance and mounts for mudguards.
