Does new force rear derailleur (2*12) have new internals/better shifting/better chain management compared to old force?
I see they added oversized pulley as red has but wonder if it is worth upgrading?
Also my 5 cents: new shifters seem owesome (thinking about upgrading existing force to new rival), but they seem to add +1.5cm to the reach, so may need shorter stem which is not so easy if you have integrated roval cockpit or some other integrated handlebar…
Also they did great job making dual-sided powermeter being non-integrated into chainrings, because it’s costly to change your powermeter every 25-30k kilometers. But unfortunalely it doesn’t work with existing cranks, so as soon as my/your chainrings with powermeter worn out, there is a need to either change cranks + chainring (to new force model with exchangable chainrings and powermeter) or maybe switch to pedal-based powermeter, because there is no sense in buying powermeter integrated into chainrings anymore…
