          Comments about Shimano SLX M663 Oe Rear Derailleur:

          I was piecing together a frame and decided to go with a 1X10 setup and read about how great the clutch type derailleurs are. I was going to buy the ZEE free ride model for it's short cage but wasn't sure if I was going to stick with 1X10 or not since this is my first mountain bike in 10+ years. The derailleur came as described - sans retail packaging but was brand new and installed perfectly. Paired with a Zee shifter, this bike shifts GREAT uphill under load with me stomping on the pedals. Shifts are quick and positive and I heard no chain slap. Great deal!

            I Buy this Shimano SLX Sl-660-10 shifters and a SLX M663 Rear Derailleur to upgrade my Deore 27 speed system. I'm a one handed rider and I do not have time for troubles when I'm in the mountain. These shifters are very reliable, smooth and precise. I'm certain which gear I'm using even I remove the VDO part to accommodate both shifters and both brakes in one side of the handle bar. I feel happy and confident with this purchase.

              I got this derailleur when I upgraded to a 10 speed from an 8 speed alivio set up. World of a difference in shifting this made. Crisp, clean shifts... and not to mention not having a chain drop since the switch! SLX is definitely in the sweet spot when it comes to the price/performance ratio.
