Oh! I know… I know… Me…Me… Put’s up hand.
Clears throat. Hmmm!! OK…
Hope made the “original centre-lock” on the Ti-Hubs. Unfortunately the spline was much bigger with less teeth, and so is incompatible with shimano. There was a couple of adapters made for 6 hole rotors, (Sachs did them at the time), but there is probably no way you’ll get an adapter from Hope spline to Int Stnd 6 bolt fitting nowadays. What you’ll have to do is take a 5 bolt rotor in the correct size and the alminium spyder you’ve already got, fiddle about with washers and spacing for 10 mins, as these old hubs had a diffrent horizontal spacing to newer Int stnd ones, and it should fit. Speak to the guys at Hope for more info.
