HI ,
i had an endurance road bike "scott speedster 2015" with endurance geometry , headtube is 13.5 cm , stem spacers originally installed with bike is 4 cm .
I purchased a new frame "scott addict rc 2011" , it have racing geometry with 10.3 "cm head tube "3 cm more than the speedster" , slightly longer reach and top tube .
i feel that riding on the hood on my speedster had more upright position than i want , however i can't ride on the drops for long time .
now when i'm installing the new frame , i need to take measurements to cut the fork ( stack on new frame will be 3 cm lower) .. i'm not sure how much spacers i should use at first ..
