DURA 2 SOLAR
GPS Bike Computer
The ultimate training and adventure companion with an ultra-thin profile and the world's longest battery life.
Seriously
sleek
DURA 2 SOLAR
Built for cyclists seeking performance, endurance 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 backplate and a tapered aluminium alloy bezel combine for an elevated look with the tactile feel of high-grade materials.
Only 99 grams, made possible by the aluminium alloy and carbon fibre combination, both chosen for their strength-to-weight ratio.
A 30% larger screen and 17% higher pixel density than DURA 1. The 3.5-inch Memory-in-Pixel screen is optimised for outdoor viewing in direct sunlight.
On the sunniest days, the monocrystalline solar panel adds up to 2 hours of ride time for every hour of direct sun.
