Is the cable long enough that you can remove some of the outer sheath to give you more inner cable exposed?
It definitely is, and that is precisely my plan until I get the supplies together to make up a set of cables for the bike. So far as I can tell, nobody ever made nice lined cables for the NF, so I figure I'll just make all the cables up from some parts from Venhill in the UK.
It'll make the brake and clutch a bit nicer to use too.
