Ciclosport CM 4.21 HR Computer

This new wireless cycle computer features not only with its modern and innovative look, but also with its PC configuration. This means that all accumulated data can be read-out from the device. The CM 4.21 is the perfect attender for the ambitious cyclist on ample tours. Due to the TwoInOne system it is possible to use two different wheel circumferences. The CM 4.21 therefore can be used for two bikes and be upgraded with optional cadence and heart rate functions.

  • Huge, easy to read 3-line display (up to 10% larger than in the previous model)
  • Individually configurable display (Multi Choice System)
  • Aerodynamic design, scratch resistant casing
  • Save your totals on your pc and set-up the device with a software interface
  • Ease of use due to integrated rubber coated buttons
  • Quick and easy to operate using the simple menu structure
  • Ease of use due to our Twist Klick handlebar bracket
  • Multi Lock handlebar brackets, also suitable for bike stem installation

Rated 1 out of 5 by Disappointment I purchesed it a while ago now and can comment on its reliability. Basicaly it has a reception/signalling coding problem. My item keeps receiving strange signals with speeds of 190km/h or other weird values. My today's max descent speed was recorded at 98km/h. HR reception is equally poor and unreliable. 18 May 2014
Rated 5 out of 5 by Happy cycling Am a happy chappy with my Ciclomaster 4.21 cycle computer with heart rate monitor. Had done just over 1,000 km's the past 5 weeks and just love the easy functions of the computer. Just looking out for the wireless cadence sensor when that will be available. 19 February 2014

Cadence Monitor?

Hello,

Is this compatible with the Speed Transmitter Kit 2014 currently being sold on CRC for £12.99? And am I correct in saying that it calculates cadence?

Many thanks,

Does this unit come with the HR Transmitter? The "includes" line suggests it comes with it, but the description paragraph suggests it's an optional upgrade, which is right?
