"One new equipment addition this year has no significant effect on his Cav's on-bike performance but does make it easier for staff (and the public) to see what he's doing at any given moment – at least when he's riding, that is. The team recently unveiled a project undertaken with sponsor HTC (a major mobile phone manufacturer) and internet giant Google.  Riders carry HTC Legend mobile phones with them during each stage (housed in a small bag beneath the saddle and weighing under 200g in total) and they're paired with each rider's SRM power meters and speed sensors via the ANT+ wireless protocol.  Assuming the riders are within range of a cell tower, this lets team staff track each rider's speed, cadence, power output, heart rate, and even exact position via the phone's on-board GPS in real time – thus aiding the team's ability to make tactical decisions while also providing a better snapshot of each rider's condition." - Chester
