Thought I'd share with you the weights from having stripped down my new Dura Ace 7800 rear mech.
Pivot bolt (DA) 10.38g
Pivot bolt (SRP - Al) 5.94g
Pullet wheel bolt x 2 (DA) 3.99g
Pullet wheel bolt x 2 (SRP - Al) 1.34g
Cable bolt (DA) 2.37g
Cable bolt (SRP - Ti) 1.50g
Total savings of SRP bolt kit for a DA 10 speed DR-7800 2004 rear mech 7.96g. For the obsessives, you could switch the Ti cable bolt for an Aluminium one and save a further 0.7g.
For the record before tuning 181.66g. Without barrell adjuster 177.42g.
I'm running my DA 7800 mech on a mtb with XT shifters. The shifters have barrell adjusters, so the adjuster on the mech gets dropped.
Next stage is to replace the mech plate with Carbon Fibre. Expected saving 3g. Expected final weight 165g.
