Sigma may not be as well-known as the likes of Wahoo and Garmin, but its ROX 11.1 Evo is an excellent bike computer, combining a user-friendly interface with riding and training data. Compatibility: Heart rate, cadence, electronic shifting, power meter, smart trainer.

Navigation: Limited to a breadcrumb trail, but it does sync with Komoot.

The Sigma ROX 11.1 EVO is smaller than many other bike computers.

Read our full Hammerhead Karoo 2 review.

With a high-end processor and screen to run, the Karoo 2’s battery life isn’t great at around eight hours though. Instead, Hammerhead interfaces to third-party software such as Strava or TrainingPeaks for any more detailed post-ride analysis. The phone app just passes data back and forward to the Karoo 2 without any user interface and the web app has limited functionality, although it does let you plan or import a route and keeps a record of your rides, routes and workouts. The Karoo 2 was the first cycling computer to give you climb profiles on the fly as you ride, so there’s no need to pre-plan a route to display gradient and distance to the top. The resolution of the sharp colour touchscreen is also much greater than competitors. It’s based on an Android operating system, which gives you fast screen response and Android-style fields and gestures. The Hammerhead Karoo 2 does things a bit differently from other cycling computers.

Screen: 3.2in/81mm colour touchscreen, 480×800 pixels.

Compatibility: ANT+, SRAM eTap, Campagnolo EPS, Garmin Varia (but not Shimano Di2).

Training data: Speed, altitude, power, heart rate, cadence, calories, gears (for non-Di2 electronic drivetrains), distance, time, temperature, navigation, performance monitoring and more.Navigation: Fast rerouting even over complex route networks, on the fly climb profiles.The Karoo 2 is based on an Android operating system. Read our full Garmin Edge 1040 Solar review.Garmin Connect also enables you to integrate data from Garmin smartwatches, to give you 24/7 fitness and training status analysis. It links automatically into the best-in-class Garmin Connect training infrastructure, giving you route planning using Garmin’s heatmaps from its rider community and lots of post-ride analysis options that others make you pay for. It’s highly configurable and records loads of training stats. The Edge 1040 is much more of a training aid than just a ride recorder, so it gives you your training status, recovery time and more. Size-wise, it’s a large device, a tiny bit larger than the Edge 1030 Plus, but it’s got 64GB of memory, so it can store twice as much data. There’s a non-solar option as well, which costs less. We regularly gained 10 minutes per hour of extra charge on summer rides. Garmin’s latest top-end computer has a neat trick – there’s a solar glass screen that can extend your runtime up to an industry-leading claimed 45 hours. Screen: 3.5in/89mm colour touchscreen, 282×470 pixels.Compatibility: ANT+, Shimano Di2, SRAM eTap, Campagnolo EPS, Garmin Varia.Connectivity: ANT+, Bluetooth, WiFi, USB-C.Training data: A huge number of training metrics including training status and load, VO2 Max and recovery time.Navigation: Full colour with turn-by-turn routing and rapid rerouting.To learn more about how and for what purposes Amazon uses personal information (such as Amazon Store order history), please visit our Privacy Notice.The new Edge has solar charging.
