I'm sure others can say the same about bike stuff that we all have splurged on on occasion.

I'm pretty sure this stem will be going on a bike where it fits well. What other stem would one use on, say, an Alex Singer?

And I checked out the pictures closely -- whether or not the stem has a light switch is undetermined (it's hidden obviously) but if it doesnt, the stem can easily be retrofitted to do so. You'd need this stem...or a custom to have this feature.
