    brake cable problem

    i bought a used 2011 specialized roubaix elite carbon fiber frame, everything but the drive train, for a great price on ebay.
    i also bought a complete 2012, 105 take off group set on ebay for a great price.
    i an assembling the bike now and everything is going nicely until i put on the brake cables. when i put the cable end cap on the cable housing it won't fit into the tension adjusting nut retaining cup. the cable will fit into the cup without the cable end cap on it.
    the cable housings are new jagwire, and the cables are original shimano cables.

    can i install the cables without the end caps? or should i try shimano cable housings?

    the group set came with the cables but only had 1 brake cable housing, says shimano SLR on it, and there were no end caps on it.

    thanks for the help in advance

    If the housing has a good fit in the fitting, you can live without the ferrule, who's purpose would otherwise be to match the housing and fitting diameters. But without a ferrule you want to be extra careful to cut the housing to a square bottom. If the housing is still uncut, use the machine cut ends for the non-ferruled end. Or use a bench grinder to square up the cut.

    The ferrules also provide for the adjusters to turn easily without twisting the housing. If your adjusters need to turn, you can pull away the housing to ease the pressure so it won't twist with the adjuster, or drop in a small brass, or SS washer when threading the wire (but it's Christmas eve, so you'll have to wait until Wednesday). BTW- I always add a washer in turning fittings when I don't use a ferrule.

    Shimano brake calipers do not require end caps on the brake housing where the housing enters the brakes. You may need them on the housing ends at the frame fittings but not at the brakes themselves.

    OK THANKS.
    i have a 2008 roubaix i am upgrading from and it has caps on the cable ends so i thought it should have them on it.
