Take the hint and go to Rohloff14 or Pinion. 1x is the sickest joke ever for a tour bike, no top end.
The KOGA world traveler is alu and very durable.
My R14 is still getting better at 21,000 miles. It's impossible to make it fail. I have it geared high, 21 to 109 with a chain. So what if I have to push a few miles.
Sure beats busted spokes and goofball shifting. SA XL Dyno drum brake on front and cable TRP Spyre disc on the back, stops on a dime anytime.
