Great Product with great price. Used my bike last Sunday for a 100 mile ride with the new Shimano 105 and couldn't believe the difference from the basic Shimano 2600.
The 105 5700 levers are super shifters... These were a replacement for Ultegra 6600 shifters. They are every bit as good if not better: the shifting action is smooth and the shape of the lever heads is very comfortable. And of course they also have the hidden cables that my prior levers didn't (which was the main reason for replacing them).
Installation on the bike was a straightforward job, especially with the included cables and cable housings.
Finally, a great price from Merlin!
These are great value and I can`t discern any difference between these 105 shifters and 6600 Ultegras
