I was told it's lighter my Nomad is 17kg & the new Ogre is 14.2 kg ?
Both of those can be true. But not if you compare like with like. You could build a 14.2kg Nomad or a 17kg Ogre.
I've just swapped the Ogre for a Nomad, here it is
IMG_20220807_124312 Most of the stuff swapped straight over, mudguards are new, stem is longer, same model of tyres but 40mm instead of 2".
I also have some new digital luggage scales, tested with some known weights and more accurate at these weights than using the bathroom scales.
Ogre (XL) 16.7kg
Nomad (61L) 15.8kg - I included the unfitted light, but haven't subtracted the bit to come off the steerer. Unlike the photos - weighed with the same pedals.
Half that difference is the tyres and tubes, but the Ogre is designed around bigger tyres, I tried it with the 40mm's and it wasn't pleasant.
Weight and the peripheral differences CycleTourer highlights aside, they're quite different bikes. They ride different, sure there's plenty of overlap, the Ogre a better bike off road, the Nomad better on, you could do the same rides on either, though the choice of which is better would depend on your use.
But if your objective is a lighter bike, for when you have to lift it, this isn't it. I may have said this once or twice before - The weight difference between steel touring bikes is minimal, a few 100g's at most, the rest is in the build.
