ive just stuck a dc tech 2 on my kuwi kz,ive positioned below the cross brace on the bars as was meant to be and its on the right side to use as a back brake,now heres my poser im left with loads of slack on the current rear brake cable due to the positioning of the lever,what i need to know is would a front cable now do the job for a rear as the distance it has to cover is that much shorter??whats the length of a nos dc front cable???any help appreciated
