I have a 1st generation Dura Ace crankset, running 54 42 rings.
Block is 6 speed Dura Ace 13-18.
Front and rear derailleur is 1st Generation Dura Ace, including original Crane DA mech.
Given I am no longer 18, to make bike more useable for club runs and some long retro training miles, want to make gearing more user friendly.
Question for those more knowledgeable than me, I propose;
Fitting alternative chainrings, probably 130 bcd modern Stronglight 39/52. Will these fit my crank without alignment issues etc. Any recommendations - source for original D Ace or some other maker?? I am concerned about chain alignment, faffing with spacers etc.
Want to fit a 14-28 block to original Campag Tipo hubs, rebuilt onto modern Pacenti rims. Will the Dura Ace rear mech cope? I read on original DA data on velobase, it can take a 28, but anybody know the realities. Also, sjs sell 6 speed blocks with middle aged man ratios, but any recommendations.
Any particular chain needed, or any 6 speed do? I rate kmc over sram and Campag, but that’s on modern setup.
Also, I have the original dura ace bottom bracket fitted. Apparently this has a peculiar offset and taper. Whilst it’s in great condition, if I were to “save” it from punishment and fit a modern alternative, what are my options?
All advice appreciated.
