Quad Lock 360 Arm - Knuckle Adaptor

I was worried the extra piece would make the setup feel flimsy, but the knuckle adaptor locks in rock solid and gives my phone just the right clearance from the bars. Being able to add that extra height between the mount and index head makes a huge difference for clearing my brake lines.

Bought this to raise my phone a bit higher on the fork stem mount, and the extra height from the knuckle really does make glancing at the GPS feel more natural. Fits snugly between the mount and index head with no wobble, which is exactly what I wanted.

The knuckle adaptor slots perfectly into my existing handlebar setup and raises the index head just enough to clear the windscreen. Took maybe five minutes to swap in, and the locking mechanism feels rock solid on the highway.
