Just checked out the website & I believe they are referring to bottom out force not actuation force, so these should be very comparable to MX blacks weighting wise. They have another keyboard on their site that has Outemu Reds & they are claiming 60g for them so it's either bottom out force or they're just talking out their ass.
According the their website this switch need 80g of force for actuation I believe. BUT +/-10g
They claimed this switches are their brand/design (Canyon black) and still if 70g is needed for actuation and 80g for bottom out... it's too heavy I guess. From what I know BLACKs in general ar near 60g which is acceptable but 70g
Please check the attachment.
P.S. And yes, they stated Outemu Reds are 60g and again +/-10g so let's say 50g for actuation and 60g for bottom out which is normal for Outemu I think.
