2008 Vegas Low, just starting my 4th season on it, 6750 miles on it. On the way to work today it snapped as I was shifting into 4th gear. Everything turned out well... the bike is in the shop. A Google search indicates that this isn't at all uncommon; some foke report having one snap every 5K miles. Any new, good, technique that can be employed to extend the life of the cable?
