    Default Rear corse brake caliper holder

    Can somebody tell my if there is a difference in the corse rear caliper holder for the 851 and 888?
    With difference, i looking mainly to thickness between them.
    Could it be that the one for a 851 is thinner then the one used on the 888?

    Henk I would have thought as the speed of the machines increased and the size of the rear spindle increased that the thickness of the bracket for the rear caliper would increase accordingly. I have a rear bracket from apparently one of Foggy,s old bike that has an extra hole drilled in it for a speed sensor (Kind of makes sense as the electronics were developing). For sure the early 851 bikes did not have this feature. If you need the thickness of this one let me know and I will dig it out and measure it.

    All aluminium racing rear brackets, for the Brembo F04 caliper, are 8mm thick.

    851 racing 1991 has a different rear Brembo caliper. A big one, back from the TT1-TT2 era. The bracket looks a bit like the ones with a torsion arm on our road bikes. But it's a flat piece of aluminium. Think it's also 8mm.
