As in the one sold by Ribble and Shiny Bikes:

Anyone got one? If so could you let me know the axle-crown length?

Also, what’s it like – how’s the ride and the steering precision with it?

Any other similar recommendations? Need something stiff with mudguard eyelets, without raising the front end much (and ideally not having to buy long-reach calipers – if I have to get a new brake I may as well go for a disc).

Cheers

Certain its the same fork as the Deda Blackrain. So whatever those measurements are. You’ll need long drop calipers aswell.

Pretty sure that’s not the case. From what I’ve seen, the Blackrain is a different fork (hence the different name 😉 – I believe Deda carry both). The Blackstorm is listed explicitly as being for short-reach brakes.
