    No joke – this stem is crazy light and perfect for my gravel bike. Lighter than “lightweight” stems I was considering at a much lower price.

  2. Francois

    Ultralight stem, for a reasonable price. Nice looking.
    Easy to set-up and adjust. Nothing more to say really.

    Amazing stem, I have two of these on two bikes, a 110mm x 6º on my road bike and a 70mm x 6º on my mountain bike, both flipped negative.

    Jumped over my preconceived notions – too light, too small – and got the stem with the “350” bar. Great complimentary combo, stiff, light, and compliant. Thanks for pushing the envelope in stem designs. Cheers

    There is a lot to like about this stem. It is truly light. It is 76g lighter than the Thomson X4 it replaced. It is also fairly attractive if unremarkable. My only real complaint is the T20 bolts. That is not a common size in the bike world. I’m not aware of a single multi tool that has that size. I have added a T20 wrench to my repair kit and in in the process added back 10 grams. This is a petty complaint I know but I wish it had T25 bolts. That would have made this a better product IMO.

      Hi Greg!
      Our initial production run of these stems included T25 bolts for exactly the reason you stated about tool availability. However, after further testing, it was determined that the T20 bolts were stronger. As safety is always our first concern, we made the change to T20 bolts. Both bolts passed ISO testing. Our concern was not saving the minuscule amount of weight over the T25 bolts, but providing the strongest, safest product possible. Thank you for riding Wren!
