These wheels are easy to overlook going by the spec sheet alone, but these wheels are much better than the specs would suggest. They are super responsive and more comfortable than I expected, certainly not to the level of something with a 25mm internal width, but they handle rough pavement surprisingly well. The stiffness is really impressive, I'm able to put out about 1000 watts in short bursts and I don't notice any lateral flex or spoke deformation at all. They hold air better than any wheels I've previously used, I think that is partly due to the GP5K AS TR tires, but Shimano definitely made this wheel the right way. These are probably the most stable wheels in crosswinds that I've ridden and they hold speed nicely as well. Shimano might have a more modern design in the works at this point, but these wheels are still really solid performance wise and the ride feel is amazing, they feel fast even at lower speeds which makes them a lot of fun to ride. When they are on sale it is a great value.
It is a best wheelset I ever owned
