Build finished!
Here’s the list of parts:
Frame: of course Adapt DP-B02
Handlebars: DP-H01 which is also supplied by Adapt
Groupset: Shimano 105 di2 which came from my Yoshun r086D
Cassette: ztto 10-33
Chainring: pass quest 48-35
Wheelset: 206db rsl50c from my r086d
Can possibly still be lighter with carbon crankset or higher tier groupset. I am also planning on changing the wheels to something lighter. Maybe from xcms, serenade, pertual or whichever has good value. Will try to ride tomorrow if weather is good.
