If it's any help, I recall someone saying Marzocci (sp?) do forks with a 1" steerer and British PACE forks do because the steerer is seperate from the crown - they are hellishly expensive but they are handmade and extremely light compared to others...

Take a look at PACE RACING

They do a 100mm downhill big travel and a 63mm XC fork, both fully adjustable and with remote lock-out lever.

Price ? £400-475
