Why put a 6deg stem on a 10k + all out race s-works bike that is begging to be slammed? My bran new 2019 sworks venge 54 cant be slammed to match my 2015 giant propel advance0 54 (which has been perfectly set up for me all 5 seasons of riding it with it slammed) Is Spec forcing me to buy a neg 12degree stem OR wait for an even better -17degree that would reduce air resistance more??? my 54 sworks venge di2 came with a 100mm 6deg stem.Not cool! when everything else on the bike is PERFECT. But i will love the -12deg 130mm stem if the dealer cant trade it out for me... other than that, GREAT BIKE, IF a -12 or -17degrees - this would be a great aero stem. -6deg just creating a sail to slow you down with more air --- why??? use the aero spacers if you need higher bars.
