The Good: Strong, light and looks great are the good features of this stem. I believe those features came from the the material, design and how it been manufactured. The power transfer from your body to the handlebar and front wheel is effective.
The Bad: There are few features that i dont like about this. those are the tag price ...seller price ... and .take out price..
I highly recommend this as the chosen stem for enduro, aggresive AM, single crown's Freeride, light dh and DJ. So far i really feel confidence to take out berm and fast speed single track, and i control my bike through this stem not the other around.
