You honestly think almost 1kg extra weight at the rear axle doesn't affect the weight balance of a bike or alter its handling?

Clue: it's not about racking up KMs. it's about enjoyment of the ride
No son. What you failed to grasp in the paragraph you decided to quote was that i wasn't talking about IGH at all. Nevermind comparing the two.
Not if fitted properly and well set-up it doesn't.
If you're frequently adjusting your derailleur there's something far wrong somewhere.
Yeah. Every 3000ish miles in my case. It's really no biggie. and TBH it's barely more time consuming for an experienced mechanic with the correct tools than the faff involved in removing and re-fitting an IGH wheel to replace a tyre/tube.
I do happen to have ridden many many IGH bikes. For utility bikes, touring, exploring etc. I happen to think they're great but I personally don't like the change in handling an IGH creates on an mtb I'm going to want to ride playfully. Don't take it personally though. You're not me. You clearly don't value the same bike handling traits I do so off you fuck to find someone else who might want to listen to your IGH sermon.
