Conceptual and fun, have lower friction with the wind allowing desempemnho higher in stretches of plains or slopes. Uphill, hiker spends more energy due to its geometry. Add double or triple the strength of two or more hikers making the event more fun and enhances the profile share and sync.
Materials: Carbon fiber, Cr-Mo Steel (4130), Reynolds 953, Titanium ... and the old tradional Carbon steel.
With a greater distance between axles, allows greater comfort and stability randonneur. Easy maneuverability on roads plains or slopes. More hostile roads steep slope high percentage requiring a little more effort randonneur. Even so, it is the most used on the international circuit for adding the historical, aesthetic, and technical.

Smaller distance between axles, somewhat reduces comfort but grante faster hiker in the most hostile terrains and steep and winding. Ease of steep roads and high percentage of slope requiring less effort randonneur. Currently, widely used in the international circuit by adding functional and aesthetic values.
Materials: Carbon in various combinations, Aluminum (7005), Titanium, Steel and Reynolds 953 Cr-Mo (4130)
