A straightforward product
I have been using this stem with a JRFOTO carbon handlebar for a month now. It works as advertised. There are no instructions in the box so I just used typical torque recommendations for other carbon stems along with Finish Line carbon paste. My stem weighed in at around 131 grams. You can get similar stems for cheaper, but you won't find a better price with Amazon level customer service.
