Aerostich Thermometer Handlebar Clip

Three Little Clips…

Each of these devices has a few unique quirks. The Clock Clip (#4230) is by far the most useful. It's proven to be durable, easy to read and works great on bicycles, too. The Compass Clip (#2203) has problems finding north as soon as it's clipped to any handlebar, but it also snaps off in half a second and because it's nicely liquid filled it quickly points true as soon as it's a few feet away from all the metal. This remains a nice lightweight and out-of-the-way method of having a little analog backup in case the GPS fails in some remote place, or if your and your smartphone are way off the grid somewhere.

The Temperature Clip (#2212) is the most problematic. It's also liquid filled, but the numbers are so small that it's very hard to read, almost impossible...and it's not adjustable so if it's internal bimetallic spring pointer is off by a few degrees you need to figure out by how much and then perpetually add or subtract this number to know the actual temp. Pain in the ass, but still a lot less costly than the next option, which is this really nice digital (#4266, $15.00) that reads to tenths of a degree and also gives you the humidity. On the other hand that one isn't waterproof without modification and this Temp Clip does tell the temperature sort of accurately, uses no batteries and doesn't require figuring out a way to mount it. Clip on-clip off.
