>>1151120little hard to explain, but i will try.
when you use a right (straight) handlebar the hands adopt a position like C2 and D2wrong. in order the reach correct position as C1 and D2right i have to put the A1 zone of the bar ends just as stated in D2right. that means, the A1 zone must be just same as in my bike pics, in other words, A1 zone must be positioned just to face the ulnar zone of my hand, in a straight line colinear with forearm.
in A, the bar end grip and the "horn" can be oriented separately but in mine both things are in a fixed position. but i give a shit about horns, i dont use them, that ergonomic grips were the only in market when i buy the bike. i wanted one like B, but there wasnt in market.
