Our Jet Lube Process injects the proper amount of grease END2END... not just at the tips like the competition's pre-lubed housing. This results in about 10% less cable drag. Housing is lead and dioxin free unlike some Taiwan-made housing out there. Our stainless steel cables are smoother feeling than PTFE cables, because of our proprietary manufacturing process. Designed especially to mesh seamlessly with Campy system.
