Large display

Optimal readability: With a dimension of 32 mm x 45 mm, the display of the PURE GPS is one of the largest among the SIGMA bike computers.

Thanks to the generous display, you can see your data immediately even during fast descents, or technically demanding trails, just by a quick glance at the PURE GPS.

3-Button concept

Operation via three buttons is intuitive and user-friendly. There is a button each for the Bike and Altitude functions as well as a third button in the middle as an On/Off, Start/Stop or Menu button.

Flat housing

Thanks to advanced electronic components, the PURE GPS has been designed to be flat and compact.

In combination with the new GPS bracket, the product works harmoniously on the handlebar or stem.

GPS bracket

SIGMA’s GPS bracket can be mounted on a handlebar or stem. It is stable, durable, and will keep your bike computer firmly in place even in rough terrain.


The PURE GPS is protected according to IPX7 standard against splashing water and temporary submersion.
