If i wanted to build a 1x11 cross bike with hydro brakes what Di2 gubbins would i need if i used TRP hylex brakes plus the new 'climbing switch' adapter.
Would it be only the rear derailleur plus battery, cables and climing switch?
Trying to work out if this is a good but cheap way into Di2 or if I'm better off sticking to 105 plus hydro brifters.
Thanks in advance.
