Touring bicycles are a great rental choice to discover Bulgarian nature in comfort. Designed to manage bicycle touring, these bicycles are strong enough and capable of carrying heavy baggage. They feature a long wheelbase, heavy duty wheels and more flexible than rigid frame construction. Touring bicycles are divided into the following types: trail, road, sport, tandem and recumbent. Contemporary road touring bikes feature approximately 62 cm wheel, easy handling and setting points for luggage racks. Sport/touring cycles are light, with more relaxed geometry, with narrow tires (around 26 mm tires), with at least 36 spokes per wheel and usually carrier racks. Tandem touring bikes are a great rental choice for cycling couples. They are longer and heavier than conventional bikes. In recumbent bikes riders are sitting in a leaning or semi-leaning stand with their legs in front. This position allows better comfort and aerodynamic productivity. The luggage racks may be placed under or behind the seat. Although a cross racing bike, Bianchi Volpe is one of the most preferred by touring bikers for its strength and light weight. Other include DRAG Marathon LUX, DRAG Marathon Pro, Fuji Touring, Jamis Aurora, REI Novara Safari, Rocky Mountain Sherpa, Trek 250, Koga Miyata World Traveler and Rivendell Atlantic.
