I felt like the stock 90mm stem was a bit too short when angled +7 degrees and too much of a saddle drop at -7. I took the 110mm stem off my old road bike and have it set up at +10 degrees, which worked brilliant. The handlebar drop is still there like the bike was designed for, but I comfortably get an extra bit of stem reach while being more comfortable and better balanced.
Only thing left now is the handlebars. 720mm is too wide!
