    “Sweet Stem!!”

    The Good: Rise and Length are spot on! Graphics are legit!

    The Bad: The bolts are weak, damaged 2 of them in a nasty crash!

    Overall Review:

    The Blk Mrkt Underboss Stem is a good stem for it's price, maybe not the lightest nor the best, but it's good looking and cheap! Will do the job if your not a weight weenie and if you're on a budget!

    “So-so stem”

    The Good: Looks pretty amazing in polished colour, kind of light.

    The Bad: Tiny hardware, slips like crazy, bolts strip instantly, friend of mine had the threads just rip out of the stem body.

    Overall Review: I'd be hard pressed to recommend this stem by any metric, there are lighter, cheaper, better-looking, better-performing stems out there.
