Facts and prices checked
Edge 1050 for battery and features, Karoo for SRAM riders and lower price
We rank the Garmin Edge 1050 ahead of the Hammerhead Karoo (third generation, often called the Karoo 3). The Edge 1050 has a 3.5-inch, 1,000-nit touchscreen, a speaker with a built-in bike bell, on-device point-to-point route creation, and a 20-hour battery rating, against 15+ hours for the Karoo in its default mode. The Karoo costs less, about $525 versus Garmin's $699.99 list price, weighs 118 g to the Garmin's 161 g, and integrates closely with SRAM AXS, which makes it the better pick for SRAM riders who do not need the longest battery life.
