I want to decrease the reach of my handlebars. Does it matter whether I increase the height or get a stem with a smaller length(extension?) on my bike?
And is there any way to calculate the relation between the two? Something like, a 1 cm increase in height is equivalent to a 1.5 cm increase in length?
Background : I have an old single bolt handlebar stem(see image) with it's minimum insertion not visible(if it ever had one). When I raised it enough for it to be somewhat comfortable it started creaking every time I put power while pedaling or while climbing off the saddle. I have another similar stem that is slightly more than 1 cm longer but has it's minimum insertion about 3 cm higher than what the current one does not creak at. I want to know whether it will really reduce the distance I have to extend forward. Yes seems to be the intuitive answer but I really want to know for sure because these are a big bother taking off and putting on.
Edit : The handlebars I mention are drops on a road bike.
The horizontal portion is parallel to the ground
