Great quality, shifts well on the X9 and XO systems. Strong enough to take abuse off road without falling appart.
The power lock is a one time use item
You would think that a thiner change is weaker but that is not the case here. The chain workes well and I use this on both a trail bike and a DH bike. They shift well even when dirty. The 1091 is both smooth running and quiet as well.
