Precise and fast 12v road rear derailleur The SHIMANO 105 12-speed rear derailleur combines the smoothness and shifting stability characteristic of the SHIMANO SHADOW RD design with direct-mount compatibility and capacity for a wider range of ratios. Technology Direct Mount Rear Derailleur Rear wheels are easier to remove with a mounting option for Shimano Shadow RD and Shimano Shadow RD+. The direct mount feature is designed to suit a wide range of contemporary frames with large-section chainstays, in particular mountain bikes with thru-axle dropouts. Allows for flexible frame design. No special tooling requirement (M10x1 Mount bolt, without e-clip)! Shimano Shadow RD The rear derailleur Shimano Shadow RD mechanism is intended for more aggressive riding. Its super low profile design carries many benefits. Because of its low profile and single tension construction, the derailleur does not hit the chain stay in rough riding conditions. The result is smooth and silent performance.

So lucky no scratches or damage! The packaging seriously needs improvement. The rear derailleur is packed in a thin piece of paper bag, wrapped around with a piece of bubblewrap! Credit goes to the seller for using a thick cupboard box! After all, i am still happy with the product.
