Minoura SG-200 Swing-Grip.
The Swing-Grip is an angle adjustable bar that allows space to mount extra accessories to the handlebar of your bike.
The adjustable angle of the metal stem means that it can be mounted either on the handlebar or stem.
The stainless band clip fits the diameter up to 35mm (1-1/4inch); so you can install on most stems, except ones with square dimensions.
The alloy bar diameter is 22mm (7/8inch) which should be compatible with most handlebar-mountable accessories on the market.
This alloy bar is also adjustable sideway by 20mm left or right.
