Yeah its aluminum and not actually carbon fiber. And looks like the knock off it is but I love it.

I like that it is lighter than the original Trek stem and is shorter and bring us the handlebars back closer to me, which is more comfortable for the ride. Any 60 mm stem would’ve worked, but it wouldn’t have been as light as this carbon fiber stem. Works good for a very much of a value.

Perfect for me at 80mm. Bike is a tad big and I needed something shorter to help reach so I could ride comfortably. Looks great on my bike as well, better than the original even.

Perfect fit. I had a 130mm all carbon stem and needed to shorten the stem so I got this 70mm aluminum/carbon. It actually weighed less than the 130mm all carbon. It's smaller so less material. 119gm vs 136gm.

All aluminum, just a strip of carbon over the aluminum. Such a joke. Not really any weight difference. Looks nice, only reason ill keep it is because i needed a shorter stem really bad im a shortie, bike had a 110 -6 degree. This fits n looks nice n will do for now

This item was advertised a carbon fiber and its clearly aluminum. It looks like carbon fiber and is painted with the same look as carbon, but you can see the inside is billet aluminum. The weight is the same as a similar length stem made of aluminum.

So far this is a very capable piece. Threads are good. Stainless hardware and lockwashers included. It's very lightweight and looks good on my bike.

The stem is aluminum with a carbon fiber sticker. Yes a sticker!Finish is incredibly poor with chips in powder coat, rough tool marks under the powder coat, mismatched alignment of components and worst of all sharp edges protruding onto the hole for the handle bars that would seriously damage my carbon fiber handle bars if installed.
