hallo,
a last picture of my TFR 16.3Kgs with a lot of modification and very light wheels set (no tube crest very strong regarding the weight of 330grs), so on the frame Ti kit for Gboxx and BB axle in aluminium 7075 custom to save weight, Suspension axle link in aluminium and needle bearing remplace by composite ring.
I see you talk about pedaling, in a light weight configuration the nucleon pelals very well but it's not comparative to an AM, if you have to climb longer 1hour for exemple the nucleon need more power, the rolhoff hub give grind on the 7 shorter gear and the weight of it is an advantage in downhill but worst when it climb really.
From flat terrain to downhill the weight of the rohloff hub always in rotation (more than 1kgs) is a benefit to keep speed linked to the best efficiency of suspension the bike take speed by his self, i have the same sensation on my
ION GB2, the bike accelerate his self when a classic
ion do not take speed and it's a great sensation.
the nucleon is a real pleasure machine from flat to downhill so to climb it's harder, what do you want peasure in the down or efficiency to climb?
even the position of the nucleon AM is better to pedaling and it's a progress to an enduro gearbox bike lighter but in race like DHmarathon like MEGA i think the AM in better for race and nucleon better for fun and pleasure, i think that pleasure to ride is that 90% of rider request
