Was about to say the same - triple means wider gear range (in general) and nice low bottom gear when using that 30 granny ring.From the online specs, I assume it has a triple crank set (three chainwheels at the front) so you will have a better gear ratio than most (other cyclists on road bikes) to get up the steep hills of London.
A friend of mine who is working over in denmark has a btwin, so iv not seen it in the flesh, but he has had some good strava adventures on it.
