    Mounting Computer with Cadence Question

    I am about to install my first computer with cadence, where should i run the wire, does anyone have pics of it done nicely? I cant figure out a good place to put it without 50 tie-straps all over my frame.

    djbowen1, the answer to your perhaps depends on your computer's specifics and is difficult to verbalise (no picture available on my pc). But I will have a try anyhow.

    I have a wired Ciclosport computer that uses two separate pick-ups for speed and cadence. Both are on the chainstays (left and right). From there, they run under the stays, unite under the bottom bracket (some wire clustering there) and continue under the down tube. At the intersection of the down and the head tube, the wire 'leaves the frame' and is wrapped around a brake cable.

    You cannot, I think, avoid tie-strips altogether (I must have used twelve, or so), but perhaps you could find some matching your frame colour. Maybe you could use some tape on the down tube, instead of strips. (Tape however, I guess, gets dirty and therewith spoils the optics.)

    Make sure to leave plenty of wire between the tube intersection and the brake cable. You must be able to fully turn the front wheel (even though you will never do that while riding) to either side. Otherwise, the wire might get stressed and break (e.g. when you carry the bike without controlling the handlebar/fork/front wheel). Happened to me...

    Good luck and happy RPMs!

    Mylar clear packing tape in just about invisible and lasts for years. Run the wire under the tube and tape at top, middle and bottom.

    Hope this helps,

    Sorry I don't have any pictures of my old setup.
    I had an Astrale on my Raleigh. Swapped the computer for a Vetta RT77 when it started acting crazy.

    Here's how I did it.
    Mount the computer on the handlebar. You'll have to approximate the length you'll need to get the sensors to the correct location on the left chainstay.
    Wrap both wires around the front brake cable. Split them off near the end of the brake cable (use a tape at the point where they split off) and run them along the left side of the down tube, close to the front derailleur cable.
    Tape the wires along the down tube about 1" from the head tube.
    Use another tape in the middle of the down tube.
    Use a third tape about 1" from the bottom bracket.
    Route the wires under the bottom bracket.
    Install the cadence magnet on the crankarm.
    Position and install the cadence pickup on the left chainstay. Check to make sure it is close enough for the cadence feature to work.
    Install the speed magnet on the spokes. Position and install the speed pickup on the left chainstay. Check to make sure it is close enough for the speed function the work.
    Wrap the excess wire in a loop and tape it to the chainstay. You can also pull the excess back to the head tube and wrap it in a loop and tape it there. That's what I did.

    You may have to play with the exact locations of the pickups to get everything to work correctly.

    You may find that occasionally your left foot will hit the speed sensor and you'll have to stop and reposition it. You'll know you've hit it because the cadence will be working but your speed will be 0.

    If it will help I can send you a PM with pictures my current setup (not Astrale).
