wireless is a doddle, i can't see wired being much harder, just as with the wireless one, you need to get the sensors in the correct positions, the only added task is running the wires neatly/securely
there's a detailed install guide with pics in the manual, you can download it here...http://www.srm.de/index.php/us/download ... em-english
I presume though that a wire needs to run up to the head unit too?
Strange question, but does it do heart rate if it isnt wireless?
if you are considering buying, have a look at the quarq powermeter, similar to srm, but lower cost, they are both very good systems
also, do not buy from uk without looking elsewhere to compare pricing, for instance try...http://www.powermeter24.com
the website is in german, but it's easy enough to figure out what's what, if you get stuck email them, i've dealt with them in the past and they were very helpful
buying inside the eu you still have consumer protection and warranty rights, on some items you can save a lot vs. uk
