I have been using the Sigma (1600) RDS Wireless. I have to check often to see that it's operating, and then have to fiddle with the sensor position a lot to get it working/reading again. Needless to say, it's a hassle to have to do this. This is Sigma's older generation system- I don't know anything about their newer ('digital?') incarnation, perhaps someone here does.
I've done a search here and what I've come up with is that the Cateye Micro has a well-favored status with MTB BikeForum users. I'm leaning toward it, what have you to say on this?
And yes, I DO consider just riding and having fun my main focus on the bike- but I also like having the computer info as well.
Your opinions and recommendations are appreciated. Thanks!
