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.

The Bottom Line
We haven't scored the Sigma ROX 11.1 EVO, and neither has anyone else we can cite. It's here for its verified specifications and dimensions, which is what the fit tools run on — a score is an editorial judgement, and we don't hand one out until someone has a basis for it. What this page can tell you is measured: 55g, $250, and how both sit against every other navigation & electronics product we track.
Weight checked against the manufacturer on 18 August 2026 — see the source. The price above has not.

How it compares
Against the 11 navigation & electronics we hold published specs for.
At 55g the ROX 11.1 EVO is the lightest in the category we track, against a category median of 93g.
At $250 it undercuts 8 of 10 of them, against a median of $350. That works out at $455 per 100g — above the $368 median for navigation & electronics.
Weight and price come from published specifications. Cost per 100g is a blunt measure — it rewards light gear and says nothing about durability or whether the thing works — so treat it as one input, not a verdict.
