The following list is what I intend to carry on my trip.  It is based on previous cycle touring trips I have made, albeit on a much smaller scale.  I tend to think that you need the same equipment for a year as for a week.  Clothing, I will keep to a minimum, as this can be easily and cheaply replaced en route.  I have indicated alongside the list where I use a specific make of equipment, or where I have a specific reason for taking a certain item. 

All the equipment, incredibly and as the photos show, is carried in two rear panniers, and I also carry a front bar bag.

(For details of my bicycle and the equipment on it, click on "The Bicycle" button on the Home Page.)

Pannier covers - Bright yellow.  Offer some water resistance and lots of high visibility.

Front Bar Bag - Altura Orkney 8 litre capacity.  Fixed to the handlebars using a Klikfix system.

  There are too many for me to carry.

Clothing

• For the Bike:
  
  Cycling Shoes - 2 pairs of Shimano SPD trainers
  Shorts - 2 pairs
  Shorts liners - 1 pair, to be worn with casual shorts
  Vest tops - 2 dry-fit.  They provide a much needed insulation layer, even in hot weather, when sweat can cool quickly in the wind
  Cycle tops - 2 Gill tops, loose and
  comfortable
  Leg and arm warmers - Invaluable for converting short sleeves to long, or to survive long descents
  Gilet - This is a very lightweight, sleevless zipped top which provides an effective windbreak when conditions demand it.
  Scarf - Home made from white linen - a multi-functional and invaluable item.  It has saved me alternately from sunstroke and hypothermia on several occasions.
  Waterproofs - I use a Gore jacket, Gill overtrousers and Goretex overshoes.  (Cold, wet feet can be demoralising and dangerous on a bicycle).
  Helmet - I don't always wear it - it depends on the conditions I face.
  Glasses - Bolle Parole come with four different lenses for any lighting conditions
  

• For off the bike:
  
  Sandals - Light and basic for campsite and hostel wear
  Shorts 
  Lightweight cotton trousers - Cut off trousers give more flexibility
  2 t-shirts - Coolmax fabric is easy to wash and dry
  1 long sleeved shirt
  1 micro fleece - Can be bulky but is needed for cooler evenings
  Swimming costume
  Night shirt
  Underwear - Wear one, one to change
  Base layer - Helly Hansen - very light and gives a warmer night time option
