Trek computer node 2.1
I bought a Trek 920 yesterday, with a node 2.1 computer. The LBS did some basic stuff. But I need to do the detailed stuff. I think I'll like the altimeter for cycling and hiking in the mountains. HR monitor because I'm an old fart. I'm about to go on the website for the 1st site. Any advice from you?? By the by, I am a computer idiot.
