These pedals would have received 5 stars if not for the fact that the gray finish comes off way to easily.
Very lightweight, easy to use and long lasting otherwise. I have used these pedals in the past on both road bikes & gravel bikes.
If you want to ride two-bolt SPD pedals on a road bike, this is as good a way as I can imagine. These pedals are light, well-finished, with really nice bearing quality. I rode LOOKs for years, so I find "toe-ing in" familiar, but some riders may have to adjust to how these hang. With a few hundred miles on them, I've had no problem with the finish scratching or chipping.
Shimano pedals continue to be the smoothest rolling after the most abuse with little or no maintenance. These replace the PD-A600, essentially the same pedal previous generation, which I used on my road, gravel, and CX bikes, outlasting similarly priced crank brothers and time atac.
Im a fan of Shimano SPD in general and these do not disappoint...
Light weight at 280g
Simple to maintain and work on if needed
Great roadie option for cyclists who prefer a more road like SPD pedal option
They can be hard to clip in as the pedal is weighted oddly that the toe portion isnt usually rotated north.
I have tried numerous types of spd pedals from Shimano, the Shimano Ultegra road pedals, Time Expresso, Speedplay Frogs and these are my favorite pedals for road and gravel. One sided but feels like a road pedal with no hotspots.
My favorite road pedal is the Time Xpresso which is light and easy to clip in and out. Cleats are not durable. Wanted to switch to SPD so it is easier to walk during bike tours. These come closest for me to road pedals. Some platform to transfer power and bottom of foot does not get pressure point heat from small MTB pedals even with the Speedplay Frogs.
Among the Shimano SPD pedals I own (M9000, M8000, A600, and this new ES600), the ES600 is the latest and lightest pair. It's similar to A600, but very slightly lighter. Since it's single sided, it is not as convenient as M9000 or M8000, but the difference is not that significant for on-road use. The only downside is the paint of the surface. It can easily get scuffs during your first ride. A600 has the same issue, but overall I prefer the appearance of A600.
