You have no such accurate remembrance  
  of a country you have driven through  
as you gain by riding a bicycle.  
~ Ernest Hemingway  

With the changing season it is common to need an extra layer of clothing at the beginning of a ride and as the day warms to strip off the extra clothing. In the last few years we have had two riders get their jackets tangled in their back wheels. The first instance resulted in a frustrating hour of cleaning bits and pieces of clothing from the rear cassette but no crash. The second was much worse, resulting in a crash and broken leg! Make sure your gear is stowed safely with no chance of it getting into your wheel. Don’t ride with a jacket tied around your waist. And when you stuff a jacket into a back jersey pocket, make sure it is completely contained and doesn’t have a sleeve hanging down that can get caught in the rear wheel. So, when taking layers off, store them safely and don’t be like Isadora Duncan.
