    how important are the cable ferrules?

    So my new BB7s arrived today with spd 7 levers and some blue cable housing and new cables. Stupid me forgot to order some ferrules. How important are they? Do I actually need them or not? I can't get the old ones off the old cables. So I'm wondering what will happen if I install new housing without them? I'm thinking the housing won't last as long.

    Well, I'd definitely recommend using ferrules, but I'm not sure you're required to for brake housing...there may be some requirement due to the differences between disc brakes and standard brakes that I'm not aware of. Many road bikes don't use them, for what it's worth. Older road bikes have cable stops that are too small to accommodate the ferrules--they're just large enough for the brake housing. Many modern STI brake levers are the same way.

    Shifting ferrules are much more important, for the record. The ferrules keep the compressionless housing from coming apart.

    When building up a bike or installing new cables, I personally use ferrules. They're cheap and easy to get. Many times the bike shop will just have a few laying around that they'll toss your way without charge. Seems like a small price to pay to avoid the potential of ruining your housing and losing your brakes mid-ride.

    With compressionless housing they are essential, with spiral-wound housing, they are a really, really good idea.
    Do you have an LBS? They'll have some.
    Seems a shame to mess up a new brake installation over them.

    Go get them, especially if you're counting on them for mechanical discs. Without ferrules you'll have a really mushy brake lever as well as a larger opening for dirt to get into the housing.

    Cool, I'll pick some up. I was just wondering since I wanna get the new brakes on and start breaking em in, my LBS is closed on Wednesdays. No matter, I'll just pick up 4 tomorrow morning and finish the brakes then.

    At first on the shop or workshop floor they make no difference, so lazy mechanics who don't ride often don't fit them. But out on the trails they make all the difference in the world, a helping give consistent braking action.

    Are you talking about cable housing ferrules or cable tips? If it's housing ferrules and they are too big, you need to go find the correct size of ferrule. In my experience I've never had to clamp housing ferrules, they just slide on snugly and stay.

    housing ferrules. I have to go in the morning and get some. would be nice if I could get the old ones off, but they ain't budging. Which is why I figured they needed to be clamped.

    no need to clamp them. when you set everything up and the cables have proper tension, they will stay put.

    Oem cables may well have crimped ends as they can be assembled in a factory as stock lengths of outer with ends firmly in place for packaging/storage. Normally you don't crimp as that could lead to increased drag on the inner

    try gently heating up the old ferrule with a lighter, then pull and/or wiggle the ferrule off with a pliers (without squishing it!). This will work if they crammed some housing into the ferrule when they originally installed it.
