Nice set up and bike. IMHO carrying a light load makes touring far more rewarding.
I'd replace the U-lock with a lighter thin cable lock, as it's mostly to deter the amateur thief.

You also seem very light on clothes. The merino tops you can wear on or off the bike, but what about shorts etc for on the bike. It's good to have one spare of those in case the other pair don't dry out over night. Also you should think about some rain gear, booties and a jacket maybe and a pair of off bike shoes for walking to and wearing in the showers.

Your cooking set up is a classic ultralight approach. If you have experience with it are are comfortable with it's limitations great. But I've found that something like a Trangia and a small pot work better for extended tours as cyclists have the opportunity to buy and cook more varied food than ultralight hikers so it's nice to have the ability to cook something rather than just boiling water.

But there's a million ways to skin a cat and I like the way you are going.
