I've been on to their website without luck but I suppose the obvious thing to do is to phone them which I will probably do tomorrow. The other answer is to try and get hold of a wheel with the QR20 hub. There must be one around lying in somebodys shed. Really I'm looking for the easiest and cheapest option as it seems a waste to have a good pair of forks lying in the garage. In actual fact I only need them to go on an old Marin Rift Zone that I've rebuilt which at the present moment has Pace R36's which need a good service. Thanks for your suggestions.
