Other important details
Narrow risers with 2-stage speed system
The SIGMA 7 speed system has an adjustable ratio change. The
length of the travel and its loading can be set to suit the pilot's leg
length and leg position: an initial easy-to-push 3:1 ratio while the legs
are bent; then an effi cient 2:1 ratio with legs straight.
Hybrid lines
A combination of line types gives the SIGMA 7 durability and good
performance. The lower lines are sheathed to protect them from wear
and tear. The middle and upper gallery lines are uncovered, for less
drag and therefore better performance. The compact braiding and
extra coating of the yarns of the Liros-Competition lines signifi cantly
improves resistance to UV radiation and abrasion. The loops at the
line ends are sheathed, to reduce surface pressure and wear.
