The Good: Legit! This is such a light weight stem its ridiculous! It's strong at I think about 90 grams. I like the length of it. Mine is 110mm but they offer 90, 100, and 120 as well. Also loaded backs it up with lifetime warranty
The Bad: I love carbon so nothing bothers me!!!
If your goal is to lighten up your bike, this is the stem to go with! It's been on my race bike along with their other carbon products. For carbon, I think it's priced fairly as well. With a lifetime warranty, nothing to fear. This stem is worth every penny!
