10 Speed Ultegra is getting hard to find, so I bought this to replace an older Ultegra derailleur that was damaged when a chain broke on our tandem. Using the same Ultegra 6700 shifters, I think this newer Tiagra kit works even better than the old 6700 derailleur ever did! This might not be the solution you are looking for if you are a road racer weight weenie looking for those marginal gains, but I wouldn't hesitate to put it on any touring, commuter, or cyclocross bike!
Some derailleurs come with no barrel adjusting nut. This one has one and was what I wanted and needed. Great so far.
Got a bargain on the part I needed. It works very well
The derailleur works fine and was in good condition out of the box. The hardest part of the job was installing a new shifter cable in the handlebar assembly ! Now I know how it's done !
