Non aero lever reverse cable routing, any disadvantages??????

Are there any disadvantages to running the housing out the bottom of non aero levers with the cable wire "button" on top? I am wanting to run aero bars , but the standard routing gums up the works.

I'd get some cheap aero levers.

Must elaborate how you're mounting your conventional levers. Can't picture it. I understand the housing will exit the lever blade at the bottom, correct?

I have done this before

With the button / cable end where the housing normally meets the brake lever and the cable housing running between the brake lever and handle bar. It shortens the cable housing a bit and looks slicker.

I've seen it on Campy non aero levers before. I've never personally tried it, but it did grab my attention.

I've seen it and it doesn't look good. Someone drilled a hole in the back of a Campaganolo lever body and posted it here; I wasn't impressed. Seems like a silly idea to me when there are lots of inexpensive levers out there that were disigned to be used with aero routing. You also have a housing stop issue to deal with. This was on drop bars.

OP, are you using tri bars or bullhorns or something similar?

It has been done, but usually involves drilling. Like others have said, some cheap aero levers will be better. If you are vintage inclined go for the dia compe inverse levers.

Here, I hope, is a link to a picture of the routing I am talking about. No drilling required.

I did this in the mid 90's when I couldn't get non-aero hoods for my Suntour Superbe levers. At that time they were obsolete, Suntour was gone, no one cared about vintage stuff, and I was too cheap to upgrade to new levers. I drilled a 1/4" hole, obliquely, upwards through the back of the lever. The stop end of the cable went through the ferrule on top of the lever body, and the housing stuck out the bottom of the lever. It was a good way of making my older equipment work. It worked just fine, and it looked... well, not too awful. Now that Suntour Superbe levers are classic/vintage, I wouldn't do it again.

Yup, that's basically what I did, except that my solution did involve drilling. When brake cables fail, they fail at the lever end; the factory stop breaks off. If you put any kind of a kink in this section of the cable, your cable end will fatigue and fail prematurely. Maybe the mafac levers in the photo don't have this problem; my Superbe levers did, and drilling solve that problem.

I think the levers in the photo are Weinmanns. For the record, I think that's a silly way to route a cable. I'm still not certain how the cable is pulled through the housing with that setup.

Yes, I think you are right, Weinmann (or DiaCompe, same thing). The pear or barrel end of the cable is in the adjuster/ferrule at the top of the lever body. In the lever proper, where you expect that pear end, the housing stops now.

It may seem silly now, but it seemed like a good idea at the time.

Oh. So the cable is fed through the top (which would normally be the exit) and the housing stops where the cable end would normally be and the lever acts as an interupter levers does, by pushing the housing.

I wasn't questioning your reasoning, rhm. But I suspect you wouldn't have done that has $20 aero levers been available at the time.

+1. Mind you I'm not endorsing the concept, but at least in this case there's an aesthetic consistency with the klunky rack and diy lighting system. I also love the wiring diagram for that system.
[edit] I just poked around that Flickr set some more. I think he's my new inventor-hero. Forum member? I especially like the removable fender with a Radio Shack phono jack to carry current to the rear light. Check it out. In terms of durability, he says he put over 100k on that bike, although it's unclear how much of that was with the cable routing in question, or how often he changed cables.

Those are my Flickr pictures. I didn't originate the inverted brake cable idea. I think the first person I saw using it was John Vanderpoel who I believe was a far more creative bike tinkerer than I.

I'm sure the cable life is no worse, possibly better.

Here's another version with a Campagnolo lever and similarly modified Weinmann centerpull:

Those pictures are what I was thinking of. It's sort of funny in a way that it doesn't really seem to change much. I suppose the housing is shorter for the front, but you still have cables creating all that massive wind resistance. It has a cool factor to me because it's so strange but I don't like that the cables could get in the way of my hands.

RHM, after looking through that flickr photostream I think that person might be your doppelganger.

My hat is off to you, Cyqlist. I consider myself fairly handy with most things, but you are clearly in an entirely different league.

Do I have it right, then, that the cable is fixed and the lever serves to push the housing?

How is the cable housing affixed to the Weinmann caliper shown below?

Right. Pushing housing and pulling cable have the same effect.

See pictures below.

I did this about 15 years ago and can't remember every detail such as whether I had to ream out the hole in the brake arm for the cable anchor bolt to fit. I think I did deepen the slots for the cable in the top of the brake arm ends.
