Met an English girl in Austria on her bike.
We were chatting and she said she found the bike too heavy for her on corners because it was so difficult to get it up and down.
She was going to change it to something lighter.
I asked her did she know what countersteering was.
She did not, and I explained it to her, telling her to, just a Giles suggested, check what happens when you steer by pushing the bars with your thumbs, and how the bike will drop or lift or swerve instantly on minimal input.
Met her next evening at same guest house.
She had a grin from ear to ear. Said it was incredible, and what was more, she had already been doing it unknowingly, but was now doing it intentionally.
All ideas of a lighter bike were now gone. her riding partner/husband had not been aware of this utilaisation of such a technique either.
