If the VDO X2DW Cycling Computer was a car it would be a Honda. While nothing fancy, it's highly reliable, well made and easy to use. One aspect of the VDO's high reliability is a unique wireless signal system that is highly resistant to interference from other computers, high powered lights and even the worst mud you can ride through. The VDO X2DW's large screen is easy to read and has a large speed read out while displaying both the time and your current cadence. A unique time trail mode allows you to set a distance and the VDO X2DW Cycling Computer will calculate your time and distance remaining every 3 seconds making it perfect for training sessions. The VDO X2DW Double Wireless Computer features a simple fitting system using trusty cable ties and has the ability to be used on two preset bikes with an automatic transmitter recognition that knows whether you're riding bike 1 or bike 2.
