Hi,
My bike is the "Masi Uno Drop track"
it has a 73.5 degree head-angle.
my handlebar is the DEDA CRONONERO TRI Bullhorn
actually i'm running the "Deda Zero Uno 2014 Stem (120mm length)" with 6* degree riser, i have flipped it down to -6* degree.
i have my stem as lower as possible, i got all the spacers above the stem, i like the handling feel it gave me..

when i'm on the bike in a comfortable position and looking straight down i can see that my hub is 2cm back from the center of my handlebar

i'm about buying the same stem with a different length.
should i go with the 100 or 110mm ?? (actually i got the 120mm and is too long)

tnx in advance.
