I'm not *that* fast....

Picked up my new road bike yesterday from my LBS (I've moved up in the world from a hybrid as I'm commuting a longer distance). Loving the bike and cycled back from a family dinner tonight. I was hoping that I'd be able to be a bit faster after switching bikes, but checking the computer the shop fitted, I noticed that I'd done 20 miles (the journey is about 8) and I had a max speed at one point of 143mph!

Much as I'd LOVE this to be true - it obviously isn't. Any idea what might be wrong? It's a Bontrager Trip 4w (wireless). It seemed fine yesterday, but it was very windy and a bit cold on the way back tonight. Could that be affecting it?
Commute: Chadderton - Sportcity

    Probably went under a power line or something. This (and led lights) can effect some wireless computers.

    Lots of things can affect wireless computers. My old Blackburn used to steadily clock me at 80mph...while stood in the stand at Tesco. Stopping in the supermarket cafe at the end of a ride became a great way of bumping my stats. The induction loops at traffic lights can also mess them up.

    Induction loops can even efect Garmins, nobody's safe.
    I've added a signature to prove it is still possible.

    Is it a brand new bike or just new to you?

    My b/f bought a new bike computer a while ago, which our LBS set up for him, and he was surprised that he seemed to be going about twice as fast as before- until he spotted that they had not removed the old magnetic chip from the spokes!

    Ooh that's a silly mistake to make! No, my bike is a brand new bike - and gorgeous!

    PT'ed it in today as the wind is rediculous here today, but will check tomorrow and see if the same thing occurs. It was fine when I rode it back from the shop (in daylight and not under any power lines) but after reading the suggestions from various on here, I went under powerlines last night and had my flashy lights on. One to keep an eye on until I go for my six week service I think.

    I think the most important part of this is that you took public transport....because of a breeze?!

    Pull yourself together for god's sake. What are you going to do when the snow starts coming down?

    My cateye computer (wireless) used to go stupid when I had the headlights on flashmode. It seems to be a common problem. I just got a replacement light (cateye warranty service is brilliant) and noticed that the instruction sheet has been updated to warn about this.
