Koppenberg is about 20%; the problem is that there is sand between the 
cobblestones, so if the rear wheel gets into a longitudinal gap, you are 
stuffed.  I've done 25% a few times, most notably Bushcombe Lane:

at the start of the Cotswold Corker.  I only had traction issues where it 
starts to level out, due to the mud, grit, water and skog(tm) which are 
frequently to be found strewn about the minor roads of the BRITONS'
England 
in the month of February.  On the steeper bits lower down I was OK, except

for having to avoid those unable to remain upright and who were thus 
toppling gracelessly into the hedge, or the front gardens of householders 
unfortunate enough to live on the route.
