I upgraded mine for some weareone composites unions with I9 hydras and they weigh 1840 g.
The biggest upgrade is in how they ride. They feel more lively.
For me I would definately upgrade the wheels again
thats good tp know. i too can only see the benefits of these cranks.
A friend of mine who runs 165 mm on his Haibike was very impressed with the lack of pedal strikes when he rode mine the other day
I have them. I dont notice them at all when I'm riding so I guess they must be doing something right. They feel more nimble if anything . I got them mainly to stop pedal strikes, which have become less frequent.

I have changed the bars, stem, cranks and the brakes. Still have rear Sram rotor on the bike as I ordered the wrong mount for a 220mm rotor on the back. Loving the bike
