    BB Cable Guide Help...

    got a new frame to build up, just waiting on delivery for Potenza groupset. The cable guides on the BB are pretty minimal compared to cable guides on my previous frames. I'll definitely get cable rub, will this affect shifting performance? The guides are too small to fit shift cable housing.

ID:	318780Will it be worth it to put some kind of tubing to reduce friction or should I just cable it up and ride?

    Any advice and tips from your experience is appreciated!

    'brifter' is a lame word.

    I'd probably try some liner through those guides and see how it works. They might slide a bit, especially on the front derailleur cable, but you can just move it back every now and then.

    as in liner from normal shift cables? I have extra cable lengths, I'll give it shot.

    thanks!

    to use liner or not ... it probably doesn't matter.

    i wouldn't. others would. some that don't will mention the ability for moisture to collect in the liner.

    That was one of my main questions... would tubing or anything really affect the shifting performance. If not, I'll probably go as is.

    Don't do anything. It will be fine.

    Here is a pic of another old, wonderful shifting, bike's BB area

    There's sometimes a buggy.
    How many drivers does a buggy have?

    One.

    So let's just say I'm drivin' this buggy...
    and if you fix your attitude you can ride along with me.

    that's more of what I've worked with in the past... but I guess it's still just steel it's rubbing on.

    thanks guys!

    If I recall, didn't some older frames use some stainless housing without the vinyl coating to guide the cable around the BB area. Same as what they used for bar ends on vintage road bike.

    I built up something similar to yours & I agree with CX about the liners. I bought some Ashima Reaction cables that came with full length liners & grubs. So I just ran some long sections of liners all the way to the derailleur bolts. Shifts great. BTW I hope you post some pics when you have it built, I'm liking that paint job a lot.
