Building a 12-speed Di2 bike involves a couple of steps and decisions to make. Are you building a rim brake bike or a disc brake bike? Will you connect the shifters wired, or run them wireless? What cables and what length do you need? I'll guide you along the process.
The 12-speed DURA-ACE Crankset is available in a couple of different crank lengths, from 160mm all the way to 177.5mm.
There are three different chainring options:
- 54 x 40T
- 52 x 36T
- 50 x 34T
The Power Meter version of the crankset weighs 748 g, while the regular version weighs 690 g.
