Help me STW, you’re my only hope…

The relatively long steerer (by modern standards) is making it quite difficult to find a suitable set of forks for an old bike I’m trying to get sorted before the winter.

My frame is carbon so I’d like a reasonably light fork for it so this rules out steel forks like On One etc. Exotic or Kinesis etc. would be ideal

445mm a-c ideally but 425mm would probably work, too…
