Observations: The Ortlieb Travel-Biker Suitcase is the perfect addition to the Bike Tourer-Panniers for that wine-country tour I mention in the Bike-Tourer Panniers description. The Travel-Biker can be used with any other Ortlieb panniers, and also as a stand-alone rack-top bag without panniers. This suitcase style bag is perfect for packing crease-free clothing. I have had a number of customers use this for professional commuting. Carry a change of clothing to your office and only look like a cyclist when riding to and from work ‒ mostly ‒ you’ll still have those tell-tale suntanned finger tips and spots on the backs of your hands from your cycling gloves!
