check the ends, on a lot of handbrake cables, the ends screw onto the outer sleeve
I purchased a sierra one from ebay £7

cut the centre piece so that I had 2 seperate cable assemblies, then just unscrewed the ends on the outer sleeve, cut the outer sleeve to the required length after test routing it round the trike frame, then screwed the ends back on
recently I took the ends back off and used heatshrink sleeving on the cable outer, stops it rusting and rubbing paint off
