After one ride on the Qball with the trekking bars I decided I wanted to go back to the Salsa Woodchippers but before I could do so I needed another 31.8 mount for the Edge so I ordered this one from Amazon. It's longer than the Barfly but what I love about it is the device really locks in well, much tighter than the Barfly.
It's not as blocky as the Barfly and I like the length of it, the device is a little further out from the end of the stem.
It mounts clamps down using a T25 torx wrench. Much better than the started hex wrench.
