Bought on sale for a climbing century. I was concerned I would not be able to use it with my Shimano 9150 DI2 since it was not recommended. I run a sub-compact (50/34). It worked in all gears but didn't want to risk going big-big gear option. So I set my DI2 to full syncro mode and limited gear options to drop down the front to 34 when gearing down (higher up on the cassette) on the rear cassette from 27. This avoided the big-big gear selection that put a lot of stress on my rear derailer. Worked great!
These inexpensive Shimano pedals will last a very long time if they are well maintained. This is my second pair. I bought the first pair probably over 20 years ago. And they have been on a lot of different bikes since then. They still work perfectly and show very little wear. I have never had to do anything to them. I just keep them clean and that's it. The bearings are still perfectly smooth and don't have hardly any play in them at all. Not enough to even notice. And that's only in one of them. The other has no play. But it is still as smooth as glass. The originals have a polished aluminum main body. The new ones are black. And they both have the same chrome steel adjustable clip-ins. They are both easy to clip in and unclip. They are a very good value and well worth the money. If I ever need another pair I will probably buy another pair of these.
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.
I switched out my old Ultegra crankset to GRX (FC-6800) as I wanted lower gearing. As I learned that the GRX chainline is slightly different and it would be difficult to keep the old Ultegra FD (FD-6800) from rubbing I also changed out the FD to this GRX810. It's important to find and download the Shimano installation and adjustment instructions as they don't come with the components any longer. Anyway, they made if very easy to install and to adjust to prevent rubbing at all chain angles.
The GRX FD-RX810 seems very much like the 105 FD-R7000 on my new road bike. It shifts quite nicely - smooth and easy. After 26K miles the old Ultegra FD was pretty beat up and ready to be replaced anyway.
