Santa Cruz BLUR 4 C 29 R TR

A Fair Advantage

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.

Design Details:

- SRAM Eagle Transmission - stronger, better shifting, wirelessly
The next generation SRAM Eagle Transmission specced on our CC-carbon models is a radically robust, fully integrated, and interdependent wireless transmission. Built around the universal constant of the wheel axle itself, the Full Mount hangerless attachment creates a far stronger connection to the frame and the super strong derailleur provides unprecedented strength. Shifting under load is made possible due to a combination of X-SYNC technology and cassette mapping, creating seamless shifts even during your hardest power output. The new AXS Pods are extremely ergonomic and highly customizable, so shifting gears is light and intuitive. It's simply the most advanced transmission and nearly as tough as the mountain itself.

- XC or TR
The TR builds feature more travel (115mm rear, 120mm front) slightly beefier tires (Maxxis Rekon), a full height adjust dropper post, no lockout remote, and larger brake rotors. It's not a trail bike, it's an XC bike for certain courses.

- Light Carbon Frame
The full-suspension Blur is lighter than most pre-race dinners you'll eat - 289g saving over the previous generation.

- Reserve 28 XC wheels
This is the lightest Reserve MTB rim (385g or 1367g complete). The rim bed is shallower and wider, meant for the newer generation of higher volume XC tires which are popular with elite racers.

- Geo to match
The Blur's chainstay length is matched to frame size so every rider, no matter their height, gets the same balanced geometry and bike fit.

- Two water bottles
Two water bottle mounts within the front triangle mean there's enough juice (or whatever electrolytes you choose) to keep the engine running.

- No proprietary gubbins
There are no fiddly proprietary parts that could leave you stranded in a Cape Epic or Breck Epic campsite.

- Made to last many lifetimes
The legendary Santa Cruz fit, finish, and quality construction put this into a league of its own. The frame, bearings, and optional Reserve wheels come with a lifetime warranty and any service is easy to do with our Rider Support pledge.

- Chainguide
The only thing you'll be dropping is your competitors.

- Superlight™ Suspension
Our priority with the Blur was to ensure that every kilojoule of a rider's energy is translated into forward thrust. That meant making something lightweight but also really efficient. This is the (super)lightest suspension we've ever made.

Frame Sizing
If you're on the cusp between the recommended height range of two sizes, the absolute best thing is to try to ride them both. At a minimum, check the stack/reach measurements on your current bike and compare it to the new model you are looking at to get an idea of a fit you are already comfortable with. If riding the bike is not an option, consider the following.

Personal Preference
A larger size frame will be more stable and will give you more room to move without upsetting the weight balance of the bike. The larger size will put the front wheel further in front of you, which gives the feeling of security and conversely, it will require more significant body movements when you WANT to shift the weight bias of the bike. Think hard about your riding style and how active/intuitive you want it to be vs. stable and speedy. You'll need to work a bit harder to muscle the larger bike around.

Body Dimension
Not all bodies at a given height are the same. If you have longer legs and a shorter torso than the average person your height, that may push you towards the smaller of the recommended sizes. If you're all torso and arms, most likely you'll want to size up.
