Gearbox made in the way it is important to go 2x5,2x6,2x7,3x6,3x7,3x8, to not have big difference in gear ratios. This does not making my ride any more fun, but in fact quite frustrating, as sometimes it is just turns into constant switching with left and right hands to the point when I am no longer fallowing which gear is which and have to look onto actual shifters.
