Santa Cruz Blur 4 Carbon CC 29 XO AXS TR RSV Kit Mountain Bike 2025

We tapped into everything we’ve learned from years of making the highest quality carbon full-suspension bikes and added the super-efficient Superlight™ suspension to make a World Cup-winning XC race bike. The Blur isn’t guaranteed to make you a race winner but being the lightest, full-suspension carbon XC bike we’ve ever made, it might be the difference between claiming first place...or just crossing the line.
