Cinch mount equipped and 24mm EXI, so Shimano BB compatible - win!  I have a spare set as a backup in my gear box in case the carbon cranks on my bikes crap out, they seem SLX level quality and finish.

They are min-max approved.

I have them on a bike and they've been fine. Don't notice any difference compared to other cranks, they just go around like any other pair I've used...

No complaints so far and the chain rings have the splined mount which means they take smaller chainrings no problem

My only complaint with affect cranks - I have 170mm cranks - rather than have a 170mm length forge, they use the same 175mm forge and just drill the shorter length. So the crank arm sticks out more than I'd like - so same/more pedal strikes.

They are good value cranks. But IMO no better than SLX. Shimanos pinch bolt design is bullet proof as are their cranks based on my experiences. But with the RF direct mount you can drop below a 30t ring, which you can't optimally do with Shimano.

Maybe its just my paranoia with the olden square and ISIS bb setups, but anything pressure spline fit still screams check for tightness regularly to me.

interesting, who knew?  the point of this is going to 170. i don't hit the actual crank arm very often, but pedals, much more often.

Looking at the ends of the cranks, they are more beat up than I've seen with other crank arms. I'm actually debating getting some "boots" for them (like you would do for carbon cranks).

My experiences with them have been similar. Work as expected, hit rocks at times (at 170mm length). If you ride in very muddy conditions, you'll be grinding the finish down after some time (but I don't think that matters). I'd recommend them.
