Of course this is a longshot. Hoping to find a titanium 1 inch fork for my 89 Merlin. Hopefully a segmented type. Also, looking for a 29.4 Ringle for my fat in any condition.
Might be able to custom make a pair of forks for you as they make Ti forks or they may be able to replace your head tube with a 1 & 1/8th one as this one of the services they offer.
