4 mm

30 piece - 4 and 5mm Bicycle Cable Housing End Caps and Ferrule Hop-Up Kit!10 of each.... SAVE 10% WHEN YOU BUY TWO OR MORE! I've always been frustrated when I've tried to add extra color to my bike build and I can't get the right quantity or color of 4 and 5mm cable ferrules along with the right color end caps. Then if I lost one or crimped the end cable wrong, I was out of luck without buying a pack of colored end cables. Then they were also out of stock... That problem is solved with this kit, we have included (10) 5mm brake housing ferrules, (10) 4mm shift housing ferrules, and (10) end caps so that you have plenty should you loose one, or your frame has internal cable routing that requires more than just 2 per run. PLEASE NOTE: Variations between the end caps and ferrules in color are to be expected. These are Jagwire end caps with Akantor brake and shift ferrules. Included in the package is a total of 30 pieces:(10) 5mm housing ferrules(10) 4mm housing ferrules(10) end caps for brake or shift cables. Pick the color and enjoy the build. These are in stock here in the USA and we pack them here for your convenience.
