The five major ocean gyres. A gyre in oceanography is any large system of circulating ocean currents, particularly those involved with large wind movements. Gyres are caused by the Coriolis effect; planetary vorticity along with horizontal and vertical friction, determine the circulation patterns from the wind curl (torque).
Velogames Fantasy Cycling has been providing fantasy cycling contests since 1997. The centrepiece event is the Velogames Fantasy Tour de France, which attracted almost 40,000 teams in 2015.
Launched just before the 2014 Tour de France, most of Team Sky will ride the Pinarello Dogma F8 (seen here) for all road stages at this yearâs Tour. In the mountains, Chris Froome and other select riders will ride a newer frame: the Dogma F8X.
