GPS manufacturer Garmin has launched in to the power market by unveiling its new Vector system on its blog site.

The Garmin Vector enters the market as the most transferable power measuring device available as it is easily swapped from bike to bike, unlike the SRM, Quarq or Powertap systems. It is also the first system to offer measurements from each leg, an intriguing option for all coaches out there.

Look and Polar are currently collaborating on a pedal based system that has been tested by Cofidis riders this year, but they are yet to bring it to market.

The Vector system is made up of the pedal (Look Keo compatible) and transmitter (see picture below) that sits between the pedal and crank. According to Garmin the system is calibrated before being shipped so is ready to ride as soon as it is fitted to a bike.

Garmin Vector system measures power from the pedal spindle and transmits data wirelessly to a head unit.

The system uses the ANT+ wireless transmitting software (as per Powertap) so no cables are required. It will currently only work with Edge 500 or 800 computers.

According to the Garmin blog; “Vector works by measuring the normal deflection in the pedal spindle as you pedal, throughout your entire pedal stroke. With force measurements, the cadence measurements from Vector’s integrated accelerometers, and time, Vector accurately calculates watts. The force sensors are permanently and securely sealed within the pedal spindle, one of the most robust components on the bike.”

As well as the ability to quickly and easily transferred between bikes the Vector holds another key advantage, it measures power close to the source.

The Garmin Vector will be available in the UK from March 2012 and will be priced at £1,149.

    yeah, why no edge 705, it is ANT+ compatibile! maybe cos there are two signals? – surely a firmware update could make it work as it will sense powertaps… well, I’ve been waiting for this in lieu of getting powertap – friggin twice the price and I’ll have to sell my 705 and buy an 800… oh well, it’s only money, I’m currenty building my S-Works McClaren Venge up from the frameset – Campy SR 11 sp ‘n Zipp Firecrest 404s 🙂 looks like it’s going to be 10K + now – good thing I don’t have kids to put thru school is all I can say.

    As someone who spent a lot of money on the Edge 705 I am VERY disappointed it is not compatible with that unit. I certainly wont be buying an 800 to use one. In fact it will probably make me look at alternatives to Garmin.

    Yes, it’s easy to take a wheel out with a Powertap in, but how does a cassette work with a different chain? What if you’ve got a Powertap built on to a standard rim and want to use it on your race bike? It’s not that easy.

    sure, you can release a powertap wheel and ride it on another bike. what about for those of us with a TT bike and a road bike, with race wheels and training wheel sets? It’s a great concept for using power across multiple wheel sets and cranks. But you’re right is wondering about durability whent he pedal strikes the curb etc.

    Yikes !. Pedal-strike alert. !
    Hope you dont ride anywhere near the kerb…

    Eeerrrrrr……is the powertap not easily swapped out as well? surely thats easier than a pedal based system, as its a quick release as opposed to a spanner/allen key that you’d need for the pedals. Be interesting to see how they fare when they get ground against the tarmac or concrete kerb!

    Transferring a powertap wheel is easier than 2 pedals ! One quick release lever.
