Now the stem:
He is directly ordered from Amazon delivered fits without costly jewelry packaging, in a plastic bag with bubble wrap.
It has a weight of 303 g, according to my kitchen scale. Instructions for the torque values during assembly is not in, you do not need necessarily because they are printed on the stem. The rest of the information can be read on the manufacturing side.
He could be assembled easily and makes a secure and stable impression. Nothing rattles or wobbles. The angle can be adjusted in increments of 10. The construction is of the optics, a matter of taste. This, however, has the stability with 2 joints and 4 compartment screw. My confidence in the adjustable Stems with only one screw is as rather mixed when I consider what forces must keep this. Here I do not use the bike with extreme stress, but only for the road or a normal forest road.
My Conclusion:
For the slightly higher weight as opposed to a rigid or simpler, adjustable stem with a screw, you can adjust the handlebars well on their own needs and still has a stable stem. Helpful in link exchange with other numbers of degrees. Quality product for a reasonable additional charge to the stems with a hinge.
