Has anyone here had any luck getting an e.13 guide on a Giant Reign X? (2012 model). Apparently they fubar'ed the ISCG tab so badly that an e.13 cannot be clocked in the right position. (or at least thats what the mechanic that's building my bike has told me). Need some advice here, I was all pumped on riding today and this has put a big wrench in the works.
