Sigma Sigma ROX 11.1 EVO— Specs & Analysis
Manufacturer specifications, compared against every other navigation & electronics in our database. We do not test gear in the field — we measure, verify, and compare.
The Sigma ROX 11.1 EVO is a mid-range GPS bike computer with a sharp color display, offline maps, and turn-by-turn navigation. It delivers solid performance at roughly half the price of premium competitors.
The Sigma ROX 11.1 EVO occupies a compelling middle ground in the bike computer market, offering many features found in flagship devices at a significantly lower price. For bikepackers who need reliable GPS navigation without spending $500+, it is one of the strongest options available.
The 2.7-inch color display is crisp and readable in most lighting conditions, though it does not match the brightness of the most expensive units in direct midday sun. Offline map support is included, with free worldwide maps that can be downloaded to the device for use without cell service — essential for any serious bikepacking route.
Turn-by-turn navigation works well with imported GPX routes, providing clear visual and audible prompts at decision points. The routing engine can also generate routes on-device, though most bikepackers will prefer planning on a desktop and syncing via the Sigma Ride app or USB connection.
Battery life of approximately 15 hours with GPS active is respectable for the price class. It will get most bikepackers through a full day of riding, with enough reserve for the next morning before a midday charge. The micro-USB charging port is the one dated element of the design.
Sensor connectivity covers ANT+ and Bluetooth, so the ROX pairs with virtually any heart rate strap, speed sensor, cadence sensor, or power meter. Data fields are customizable across multiple screens, and the Sigma Data Center software provides detailed post-ride analysis.
For bikepackers who want capable GPS navigation, offline maps, and training metrics without the flagship price tag, the Sigma ROX 11.1 EVO delivers outstanding value.
Who Is the Sigma Sigma ROX 11.1 EVO Best For?

How It Compares

The price-to-weight ratio comes in at $333 per 100g — a premium price point, but you're paying for quality, materials, and design that justify the investment for serious bikepackers.
