Mechanisch niet sterk

Vandaag Pure 1 ATS ontvangen en op de fiets gezet, na aantal keren indrukken setknop met 0,5 mm potlood verdween setknop in behuizing en was de ATS onbruikbaar. Kon hem weggooien.


  • Duidelijk display
  • eenvoudige bediening
  • niet duur


  • sleckte kwaliteit testknop

slechte aankoop

Mooi design, duidelijke cijfers, en makkelijk in gebruik. Helaas heb ik er 1 rit mee in de regen gereden en nu zijn de cijfers niet meer compleet leesbaar. Je mag toch verwachten die een fietscomputer iets kan hebben.

  • Mooi design
  • Belangrijke info aanwezig


  • Geen gemiddelde snelheid

Detailed product description

Modern classic
The large screen, elegant shape, and restrained colour scheme all make the PURE 1 a modern classic in the Trend line. Clean looks meet serious functionality.

Sleek design
The PURE 1 stands out because of its 11 millimeter thick casing. The sleek design sets a new standard for minimalist devices. Optimal screen estate at 29 x 45 mm.

Single-button operation
A single button is all it takes to operate the PURE 1. This allows you to switch between ride and totals, even when you're out riding. The button is sizeable and has a clear and distinct "click", meaning it can be operated even in winter while wearing gloves.

Focused on the basics
The stylish minimalist computer focuses on the basics. The Sigma Sport Pure 1 shows speed, distance, and time.

Flat bar mount
The bar mount of the PURE 1 ATS has been adapted to suit the vertical design of the bike computer. The mount is flat, keeping the computer close to your handlebars.

Click magnet with pawl retention
The PURE 1 ATS uses a newly designed spoke magnet. The different levels of the pawl retention allows it to attach to all regular spoke sizes ranging from 1.6 to 2.3 mm.

Variable fixation of the ATS transmitter
The PURE 1 ATS measures speed using the ATS transmitter (Analogue Transmission System), which sends the data to the computer without wires. The analogue signal is coded and the transmitter has a range of 70 centimeters. The attachment uses a tie-wrap, O-ring, or strap and is easy enough. The transmitter itself is mounted to an extremely flexible rubber base which suits virtually any fork.

User-friendly battery cover
Typical to Sigma Sport products is the fact that you can replace the batteries yourself. The battery is stored in the new battery cover which ensures a perfect fit all of the time. The cover can be removed using a coin.

Simple wheelsize configuration
In order to get the right speed on your display, you first need to set the proper wheel size in the computer. All common sizes have been pre-programmed into the computer, all you have to do is select the right one. You can also set the size manually.
