Current Stage Info:

Saddle I am used to now (lighter as well). New and lighter rims.
From inital weight (13,4 kg) down to 12,8 kg.
Still "heavy" (steal frame and gear hub and hub dynamo).
But only the rims almost did 400 g.

Steal and "no" seattube = flex.
And it is working!
In this setup (full build) it weights 13,4 kg (frame XL). Not a for climbing, but in normal urban territory it runs really good.
