Cheers for the tip. I'm actually a transplant from Yorkshire - been here six years now.
The forks were on a MC San Andreas frame (with Goldtec hubs and original Hope closed discs) which "tore open" above the BB. I traded that in for a MC Sin here five years ago, swapping the Monstors for Marz DC Shivers at the time.
I'm planning on perhaps switching the Monstors over to a new project, provided I can replace the axle...
