>>1806569>>1806570ehh i think it can be used without, as it seems to be depicted in pic related. maybe the link will just get scuffed against the barrel adjuster. i could put some kapton tape to protect it and make a tighter fit. the adapter end cap that comes with the jagwire elite links is smaller than the POP end cap so maybe it's mainly decorative so that they can have their jagwire logo showing. there shouldn't be the same need for the end cap as for kevlar or whatever copmressionless housing.
