I don't often succumb to "I just have to have it!" but when I saw this, my tandem needed it desperately. Unfortunately, my two commuting bikes are older and have quill stems, or they'd have something too. One "issue" with the thermometer is the typical inaccurate reading when it's in direct sunlight. But it's been great for an annual week long bike ride, checking morning temps to figure out what to start out wearing.
