DURA 2 SOLAR

GPS Bike Computer

The ultimate training and adventure companion with an ultra-thin profile and the world’s longest battery life.View Pricing

SERIOUSLY SLEEK

Built for cyclists seeking performance and elevated design, DURA 2 SOLAR combines the longest lasting battery of any GPS bike computer, a 3.5" display, detailed mapping, and ultralight construction to help riders train smarter and go further than ever before.

THE HIGHLIGHTS

An ultra-low profile, woven carbon fibre backplane, and a tapered aluminium alloy bezel combine for an elevated look with the tactile feel of high-grade materials.

UNMATCHED POWER RESERVES

A single charge gives you 120 hours of ride time, before accounting for solar charging. On the sunniest days, the monocrystalline SOLAR panel adds 2 hours of ride time for every hour of direct sun* – which means you can go months without charging DURA 2 SOLAR.
