# Why is the treadling light?
Each shaft and lam is suspended on one continuous length of Texsolv cord. Each cord runs over a series of six pulleys to allow smooth vertical movement—no lateral resistance, just clean up-and-down action. To enhance this even further, Louët equips every pulley with a sealed, lifetime-lubricated ball bearing. These bearings do not wear out, and they allow every cord to glide effortlessly.
The other reason for the Spring’s light treadling is that the countermarche system does not require the weaver to hold significant weight on an open shed, unlike a jack loom. The mechanics of the parallel countermarche use gravity and the weight of the lower lams to counterbalance the upper lams and shafts. Texsolv heddles contribute virtually no additional weight.

**The result is an effortless treadle action.**
