The World Cup-winning XC bike that refuses to stay in its lane. The Santa Cruz Blur pairs a featherweight carbon frame with Santa Cruz's ultra-efficient Superlight suspension — a bike that sprints for the hole shot on race day and doubles as a wildly capable short-travel trail bike every other day of the week. Every Blur carries Santa Cruz's lifetime frame warranty and lifetime free pivot-bearing replacement. This page includes both the proven fourth-generation Blur and Blur TR, and the all-new fifth-generation Blur with 120mm of travel at both ends.
