Hey guys I was wondering if any of you route your wires through the frame. Specifically, the main roll hoops. I'm thinking they probably won't like that maybe to the holes, but we drill holes for pop rivets in the roll hoop for the firewall. It would only be two wires for about a foot. It's not necessary but would look really clean. Thanks,

I haven't seen it done that way. You will certainly need to have grommets around the wires where they pass through the steel.
While I understand the desire to have it look as clean as possible, I was always content with just cramming them in the crack where the firewall meets the RRH tube and hiding them that way.
You could also just get some wire loom or tape that is the color of your paint...

I'm familiar with all the options. It's not hard to do and yes grommets would be required. There is no cracks to put the wires so it would look cheesy to use tape or painting them. I just didn't know if the tech inspectors would allow it.

The only way to be sure it will fly is to shoot an e-mail to the tech inspectors.

They do allow it (in the past). Sherbrooke (among others Im sure) has been doing it. I cannot find the picture that I saw a while ago though.

We always run the wires through the roll hoop / cage.

What about throttle cables? Has anyone ever done that through the SIM or Floor tubes? I always hated having that one just hanging out in the cockpit.

Definitely possible. Then maybe you don't need a cable housing for the length of cable inside your tubes, but that's not really that big of a deal. I wonder if anybody routes cables in the tube on bicycle frames...

Yeah bike frames have been done for a while

Although it looks clean to route the cables inside the fram of the bike, I don't like it because having the exposed cables on the Top Tube makes them available to act as emergency controls in case your brake lever or shifter lever is broken on a trip. I've ridden trails with a hand on the front derailer cable to keep it from auto-shifting, and I've pulled the rear brake cable by hand when my shift lever was bashed and out of adjustment too. This is common practice. Also, I've heard of accelerator cables on Baja SAE cars being pulled manually during an endurance race because of a pedal or cable failure, but that's probably something you should be black flagged for if you get caught.

Aside from looks, on triathlon bikes, the internal cable routing serves to reduce aerodynamic drag. I know this sounds ridiculous when your bike has a moving, sweating, un-aerodynamic person on it, but there are wind tunnel tests showing some reduction in drag (and cross-wind drag) with internal cable routing on tri bikes. Just an FYI

I agree. Horrible and brilliant things are done to keep cars running in an endurance race. If you get caught, you have to be black flagged. I just don't want to suggest to anybody that routing the cable in the cockpit so you can yank it by hand is a "design feature." |
