A dull evening this week at home and I was browsing Youtube videos about Passo Dello Stelvio.
I found a very good Youtube channel called Cycling-Secrets Channel.
There is a lot of animated videos giving tips how to ride safely. There is a video about hand signals, cornering safely and how to ride in a group.
I found this channel very educating especially for riders attending to their first ride in a group.
Check out the website as well.
