Test-drove a Specialized Diverge up Heuberg yesterday. 550m elevation gain with a 13.8℅ average gradient is definitely a bit too harsh on a road bike. However, on gravel and with sane gradients, that thing kicks ass!
Biererei not only carries a great selection of bottled brews, but also has 4 beers on tap at their growler station. Best thing to happen to Oranienstraße in ages.
