The Domane is such a capable all-rounder, and with disc brakes,
even more so.
Trek's IsoSpeed system at front and rear makes for a
super-smooth ride without adding undue weight, and the Ultegra Di2
offers probably the best bang for the buck on the market right now
- silky, reliable shifting with a minimum of effort.
The Shimano discs provide effective stopping in all conditions,
with great modulation, and allow the Aeolus rims to be slimmed down
to give less rotating mass - the end result is a bike that
accelerates and stops with ease.
