TL;DR = works, but very heavy due to poor workmanship. difficult. It's like they're trying to protect themselves from breakage just in case the tallest people on the planet are able to use the product. Here's a hint - they don't use your product. This is a stem, it should only prevent the handlebars and weight from accidentally pulling on the handlebars when riding or climbing. He doesn't even have to weigh a kilo. It's just shoddy cheap production. Proper pouring could easily drop 4-6 ounces and possibly more. However, I give it three stars for size and functionality. But an item can be fully functional but still of poor quality, and that is exactly the case in this case. Attaching bike parts is NOT perfect and not a good production - that's why these department store bikes weigh so much (heavy frames, heavy handlebars, heavy seat posts etc) and why a real well known brand bike sold through a bike shop weighs MUCH less than a bike in the discount store.
