I'm going to neg rep the next person who tries to persuade us using a drop-stem with risers is a bad idea.
It's happens because;
a/ Nitto make stems to match your risers and it's a cool sounding name as well as being Japanese (de facto cool).
b/ EVERYONE has seen a courier with a pair of risers knocking around.
c/ Logging on to Hub Jub and spending £30 on a set of alu risers and a £70 stem is no worse than rollin' to soho and doing it in TFG.
ftfy ; )
