    Wired or wireless computer for the Cervelo triathlon bike?

    I'm about to buy a cyclocomputer for my Cervelo P2C. I want cadence on it, and I want the cadence sensor to be rear-wheel mounted so I can also use it on my trainer.

    Quick questions for people of have done this:
    - Are wired options doable given the aero frame of the Cervelo?
    - Do you have problems mounting the computer? (I have the stock Vision wing-shaped bars and am not sure whether you can mount anything on those.) Where do you mount the computer on a tribike?
    - Recommend a model, and if you use it, please share your setup! (I have seen recs of the CatEye Strada and the BlackBurn Neuro in prior threads.)

    (I did find the recent posts on this subject, but I'm still not sure about the questions above, and my LBS guy gave me some conflicting information, such as saying that the CatEye Strada would NOT work on my rear wheel.)

    I just picked up the Cat Eye Double Wireless computer. The sensor mounts on the chain stay so you get both speed and cadence even if you are on a trainer. I mounted it on my new QR Seduza with no problems at all. The computer is mounted between my aero bars and fits nicely.

    Wired can be done. Those with the older wired SRM's have just carefully taped the wires on the downtube or those with some electrical ability have drilled and internally routed the wire reconnecting once through... Same could be done for a bike computer.

    Personally I'd just go the wireless route! Many computers have a stem mount so problem sorted there as well...

    I have the wired cateye strada cadence on my P2C. Pickups for both cadence and speed share one wire and are taken off the rear wheel. Don't see anything difficult about it. It's been on there all summer and works like a charm.

    edit: Oh and you simply run it down the underside of the tube and under the bottom bracket. I have a zip tie at the top and one at the bottom. Initially used a little electrical tape along the underside of tube but it fell off months ago and I never replaced it. Can't imagine drilling a $2K carbon frame.

    I have a VDO C3DS wireless with Cadence. It is mounted to the back wheel and works flawlessly. There is NO reason to go wired especially if you want to do a rear wheel mount.
