The Good: Light, Easy Intsall
The Bad: Moves Easy After CrashOverall Review: I ran the low mount version on 1x9 gearing with my Trek Fuel EX 7. Worked great because with a press fit BB the low mount or high mount allow you to still use a chain guide. Super LIGHT The chain guide was easy to install, however it is easy to move upon crashing. The lower mount I had setup is similar to a derailuer clamp on your seat tube and it moved on me and needed readjusting several times after a bad crash.
