Goed en netjes, geen poespas

Doet wat het moet doen. Makkelijk te installeren, en fraai, zeker zonder snoertje.

Draadloze fietscomputer zonder poespas

Ik zocht een draadloze fietscomputer zonder poespas. Deze bleek in de aanbieding te zijn en dus gekocht. Makkelijk te monteren, en het scherm is goed af te lezen. Het frame kan je draaien zodat deze ook op de stuurpen gemonteerd kan worden.

prima, maar

Ik gebruik hem alleen voor een tijdritfiets. Om te weten of bij dezelfde inspanning het mechanisch rendement hoger of lager is bij een tandje meer of minder. De oude wilde niet meer nadat ik er een nieuwe batterij in deed. Ik belde jullie om te helpen bij wat ik klaarblijkelijk fout deed. Tot mijn positieve verrassing kreeg ik gelijk een nieuwe. Dank daarvoor. Als mijn herinnering me niet bedriegt deed de eerste versie die ik jaren gelden kocht het ook niet goed.

Degelijke en betrouwbare snelheidsmeter

Ik heb 12 dagen gereden met deze meter door Spanje, met heet weer, soms heftige regen en ruige ondergrond. Metertje gaf geen krimp en heeft van begin tot eind prima gewerkt.


  • Robuust, kan tegen een stootje.
  • Prima waterdicht.
  • Geen overbodige functies, gewoon basic.


  • Smalle cijfers onderaan minder goed leesbaar

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.
