Thanks, that's the review I was looking for. I also don't understand why they abandoned the weighted design. So I guess the way to go is the double sided pd-ed500
Yeah, despite my history of using single sided SPD (PD-A525 from the 80s, PD-7410 in the 90s), double sided is really the right choice unless there's something useful on the flip side.
Turn out they weight about 280g for a pairs, only 10g more than the PD-A600 (290g)
