Santa Cruz Blur 5 CC XX AXS Race Flight Attendant Reserve
Ultimate Flight Attendant, XX AXS, Reserve 28IXC SL Carbon Wheels
For Race Days and Weekdays
The new Blur is made for trails, whether you’re racing for podiums or hammering into the sunrise. The suspension, geometry, and chassis combine to deliver a platform capable of the top step, the rest is up to you.
Santa Cruz bumped up the travel, updated the geometry, and spent a lot of time tweaking the suspension kinematics to encourage you to obliterate the boundaries of a traditional “XC bike.” The Blur is right at home sprinting for the hole shot, but it’s also a lightweight and immensely capable short-travel trail bike for the days between the races. Whether you're sprinting out of the gate or out of a corner, aiming for the horizon or the apex, the Blur takes XCO and injects some 'oh, hell yeah!' into every ride, Monday through Sunday.

Reduced & Refined
Less surface area means less weight. Santa Cruz slimmed down the frame tubes, tweaked the shapes, and took a pair of shears to nearly every carbon ply to reduce the amount of material required to make the frame. Despite the weight loss program, Blur is still built tough enough for a lifetime of riding on rough trails, and carries our legendary lifetime warranty for peace of mind.
Dialed Geometry
Santa Cruz extended the reach significantly, and paired it with shorter stems (50mm on standard builds, 60mm on race builds) to make you feel more like you’re riding “in” the bike instead of “on” the bike. Combined with a 75-degree seat tube angle and a 66-degree head tube angle, the new Blur encourages and rewards hard, aggressive riding on both the climbs and descents. That steeper seat tube is also shorter to allow for better seatpost insertion and longer droppers.
