Hey Mads, what are the new bar and stem? Very impressive weight!
You chain looks very, very short and I would imagine the shifting will not be so great when you add in some extra resistance of the new clutch mech.
I have just put an Absolute Black chainring and XTR clutch rear mech on my Scalpel and it isn't an entirely faultless solution. It has only taken me 200km to drop the chain repeatedly. In the dry these chain rings seems to be perfect. However during a very muddy, very wet 60km ride in torrential rain there was gritty mud building up around the wide teeth on the chainring which stops the chain from sitting low down on the teeth like it should. The shape of the wide teeth does not allow the mud to be pushed down and off the tooth as it does on the narrow/ normal teeth. Several times during the ride I noticed the chain sitting high on the teeth then eventually clunk down and locate properly (or fall off). My opinion is that the clutch mech does most of the work keeping the chain on and the chain rings are a bit of a gimmick. Sure you can feel the chain grip a little better on the ring and Absolute Black have the pictures to prove it but I feel the effect of the new mechs is more significant. I feel a better set up is probably a normal single speed chain ring with a clutch rear mech to help the mud clear, but no-one seems to ride this combination (hence difficult to find others' experience of this). FSA are soon to be releasing the Megatooth ring which relies on a longer, more hooked tooth and avoids the narrow/ wide approach which seems to be prone to issues in thick, gritty mud... at least in my limited experience.
I would be very interested to hear your thoughts when you get the new set up up and running, especially in mud
