Blackburn Atom SL 5.0 Cyclometer

This computer is really easy to install! Haven't had it very long, but thus far, it seems to work just fine. It has more functions that I am accustomed to having, so there are stil functions for me to explore.

This is a nice unit. Screen is not too big, sensor is a little large on the fork. Altimeter is okay, doesn't give actual elevation but elevation changes during the ride. I would like to have actual elevation as well. Temp gauge is a bit off, I was riding one brisk morning and it was about 36 degrees outside, the temp gauge was reading 50 degrees. It was definitely not 50 outside.

Now the biggest flaw I found with the unit is interference with the wireless signal between the display and the sensor. While riding with my Niterider Lumina 600 headlight on, the display would constantly display 0 mph. The EMI from the headlamp completely jammed up the signal. Once I turned off the headlamp, it resumed working. I resolved this by moving the computer down to my top tube.

I thought all was well after separating the two, but while out on a nice afternoon ride, I noticed my computer was reading 0 mph again. Further investigation found that my bluetooth speaker I have mounted on my frame was jamming up the computer. Once the speaker was off, it would start working again. I moved the speaker further away from the computer and it resumed working.

All in all, I feel like there was not enough design effort put into the unit to ensure that it would work with common items found on bikes. Come on, a headlamp! A little more engineering effort would of ensured this wasn't an issue.

Installing this was really easy. Works well so far. Temp gage not very accurate- heats up in sun and reads way high, but not something I really need anyway. Altimeter is a nice feature to track gains on big hills.
Sensor is pretty big and clunky but not a big deal.
