CyclistHammerhead Karoo 3 has new internals and over 15 hours battery lifeHammerhead has updated its Karoo cycling computer. It retains the same case dimensions and screen size and resolution as the previous generation Karoo 2, but theres a wholesale upgrade to the Karoos internals, with a faster 2.0GHz processor, 64GB memory in place of 32GB and multi-band GNSS support. Crucially, Hammerhead has at the same time increased battery life from a claimed eight hours for the Karoo 2 to whats now said to be over 15 hours.This is the first major upgrade since Hammerhead was acquired by SRAM, and it has been co-developed with the brands new Red AXS groupset to offer closer integration you can configure SRAM groupset behaviour in the Karoo, instead of using the AXS smartphone app.The new Hammerhead Karoo is priced at 449.99 / $474.99 / 499.99 / AU$749.99.Read more: SRAM Red AXS reclaims lightest groupset mantle and updates ergonomicsRead more: SRAM Red AXS groupset reviewRead more: Zipp ups integration with SL 80 Race bar and Goodyear-made Vector R tyresUpgraded internalsHammerheads screen resolution was already significantly greater than its competitors, with the 3.2 inch colour touchscreen boasting a 480800 pixel resolution. In contrast, among its competitors the Garmin Edge 1040 has a 3.5 inch touchscreen with 282 x 470 pixels and the Wahoo Elemnt Roam has a 2.7 inch non-touch screen with 240400 pixels resolution.The upgrades to the Karoos internals include a new quad core 2.0GHz processor, up from the previous generation Karoo 2s 1.1GHz. The internal memory size has doubled from 32GB to 64GB and theres 4GB of RAM, again double that of the Karoo 2.Hammerhead has added new multi-band GNSS support to the Karoo, which is also a feature of the latest generation of Garmin and Wahoo cycling computers and should provide a more accurate position fix, particularly under tree cover or when riding between tall buildings.Probably due to the high res screen and Android-based internals, the Karoo 2s battery life lagged behind that offered by its competitors, with a claimed eight hours. The new Karoo improves significantly on that with a claimed 15+ hours. Its still a little lower than Wahoos claimed 17 hours and significantly less than the Garmin Edge 1040s claimed 35 hours without the solar charging option and 45 hours with solar charging. Its nevertheless a significant upgrade that makes multiple rides between charges or longer outings a more practical proposition.Hammerhead says that you can recharge the battery by 30 percent in 30 minutes, with a full charge taking 2.5 hours, using USB-C charging. Despite the upgraded specs, Hammerhead quotes a reduced weight of 118g for the new Karoo versus 131g for the Karoo 2. The new unit retains the IP67 ingress rating of its predecessor.
