Planning an all-day ride and worried your phone's battery will give up before you get to that final Strava segment? A battery-pack charger like the Powertraveller Powermonkey Discovery could be the solution.
Powertraveller is a British company which makes a very wide range of recharging solutions with onboard batteries. They have products to top up your phone as well as rather larger offerings to get your laptop or even your boat going.
Genesis's Croix De Fer hardly needs an introduction. You most likely already know that it's a do-it-all bike, and that its credentials were firmly established in 2010 when Vin Cox got the Guinness World Record for riding it around the world faster than anyone had done before.
Entries for the 2013 London - Edinburgh - London 1400km audax open tomorrow.
