This thing is almost indestructible. I've put 200 miles on it so far and still not a blemish. I would say this isn't the lightest crank, but you can swap the steel chainring for an aluminum to save a few grams. I do have the rx810/820 level crank in 170mm, but I wanted 165mm crank length just because I liked it on my MTB. I don't think the 820 level is worth the extra $100 or so for the extra weight savings and better finish.
