Strengths:
Precise shifting once set up carefully
Weaknesses:
Simply would not stay in gear under load.
Similar Products Used:
The entire Shimano range and Sram Quartz.
Bike Setup:
Trek Fuel EX 9
Bottom Line:
The "Shadow" XT mech came with the bike. When climbing on steep sections of track the chain would wonder onto the surrounding 2 cogs that the shifter had set it on. So on the third from top sprocket, for example, the chain would wonder onto the sprocket above it or below it. This was so frustrating. After endless trips to the bike shop where I purchased this bike from we checked the frame, the hanger, obviously the mech, we changed the XT cassette, the chain, shifters and even 2 front chainrings. In the end my bike shop put a current but non-shadow XT mech on.....problem solved. Naturally I think very little of this "Shadow" design from Shimano. Nothing so fickle belongs on a Mountain Bike.

Except for the weight(compare to the XTR), everything is fine. It works so perfectly and smoothly. At first, it needed some tuning, after that it is perfect. You don't have to worry about repairing by the road side. It don't give you any trouble. What a perfect rear derailleur in this price. What an outstanding valuable rear derailleur!!
