Old racers are perfect for longer tours. Solid steel frames absorb the bumpy road conditions much better than the newer aluminium and carbon frames even with narrower tires. Unfortunately most of the racer frames do not come with eyelets for mounting racks or mud guards.
On the photos you see an old titanium frame from the 90`s with Tubus Vega rack using adapter sets from Tubus (Fußverlängerung 7,95€, Schellenadapter 5,95€ (different sizes available depending on the diameter of the seat tube) ). Be careful to protect the paint job when mounting the adapters on the seat tube, and it is ready to roll. The ride was extremly pleasant!
