Can anyone tell me if the spindle, brake disc, brake caliper etc are all the same on all the 1199s or if the 'r' has any different parts apart from the actual arm? Thanks in advance.
Doesn't look like it! You could always go here & download the parts lists (right hand side dropdown) & compare part numbers HTH
All the axle, hub,disc,caliper are all the same, in fact i think the actual arm is the same its just the internal parts of the front mounting which are different due to the adjustable pivot
