First aid kit
Rain coat, arm warmers, leg warmers, glove liners and headband

Mounting Fenders:

I came across these pictures for mounting fenders on bikes with limited clearance. I received an email from Mark Meininger, who is the owner of the bike, giving me permission to keep the pictures up. The work was done by River City Bicycles in Portland Oregon. Their "wraparounds" are at:

and mounting instructions are at:

Lights:

Although there are as many opinions as randonneurs on lighting systems, these are my thoughts on lights. Head lights can be either battery or generator powered and both have their advantages and disadvantages. Batteries can get expensive over time and you need to carry spare batteries to ride through the night. P-B-P could easily use 32 batteries for the whole ride. Generators last through the night but create drag and bottle type generators can wear the tire and slip in the rain. The best generator is the Schmidt dynohub although it is expensive and I would only recommend it for someone serious about P-B-P and night riding. The Schmidt dynohub can power two 3 watt lights at speeds above 10 mph.

My personal system is the Schmidt dynohub with two 3 watt Lumotech lights and the Cateye Micro light. I carry a second Cateye Micro as a spare for the lamp and batteries in addition to the two spare bulbs for the Lumotech lights. If I need to change the Cateye, I can slip one out of the mount and the other one in. I mount the lights under the handlebars on an extension, which frees up handlebar space and lowers the lights. It helps to have two independent lighting systems in case one fails the other will back it up. Another option is the Cateye EL300 which uses five LED's instead of an incandescent bulb and provides a longer battery life. From what I have read, it is not as bright as the micro and is best as a backup light. In the rear, I use a five LED Vista light set on steady mode and carry a second one to meet the spare requirements of P-B-P although one set of batteries will last through all the brevets and P-B-P.

I have found mounting a headlamp on my helmet helps at night to read maps and road signs as well a fixing flats at night. I have used the Petzl Tikka LED headlamp which I attached to my helmet by threading a Velcro strap through the lamp and the vent holes in my helmet. It allowed me to read my map and computer as well as read road signs at intersections but it is not sufficient for illuminating the road. Another headlamp is the Princeton Tec Aurora headlamp. It has the added advantage of being adjustable as well as different brightness levels and it is also waterproof. They each have three LED’s, use three AAA batteries and will last for over 100 hours on a set of batteries.
