After a few teasers via the UCI XC World Cup, Santa Cruz unveiled its new lightweight mountain bike, the fourth generation Blur.

Santa Cruz claims it is the lightest 29-inch dual-suspension mountain bike they’ve made to date, with a frame that’s 289g lighter than the previous Blur.

VPP gives way to the Superlight suspension, which is a unique pivot design with flexible seat stays, a big contributor in terms of weight saving.

The design of the Superlight suspension is tailored to the riding characteristics demanded by modern mountain bikers. It is light and efficient with great softness.

The carbon fiber used for the rear triangle has been structured to have the right amount of spring force to achieve the right balance of flex, cushioning and durability.

All energy drinks – you can handle

Blur’s updated suspension layout now allows for dual water bottle cages to be fitted, which also makes it a perfect stage racing weapon. For hot local driving conditions, greater load capacity of the water bottles is crucial.

Each frame size is designed with chainstays that are proportional so runners of all lengths can benefit from the same balanced geometry.

As with modern mountain biking trends, the new Blur is longer and has a slacker head angle, 0.7 or 1.4° depending on the travel of the front fork. Variable seat tube angles ensure a better fit in all sizes.

The frame has internal cable routing ports for all components, including the rear lockout and dropper post. A mounting point in the chain bracket will also simplify the use of a chain retainer.

Sustainable under local conditions

It’s great to see that the designers have also become attached to a threaded bottom bracket design, which is less likely to develop an annoying creak when exposed to dusty driving conditions in South Africa.

As bottle cages no longer need to be mounted on the seat post, all models are equipped with dropper post.

The new Blur will be offered in XC and TR specs. The XC construction features 100mm front and rear suspension, Maxxis Aspen tires, remote lockout, Rockshox SidLuxe shock, and SidSL suspension fork.

Santa Cruz’s TR models offer 120mm of front suspension travel and 115mm at the rear. They also ride Maxxis Rekon Race tires and riders will have the option of a Fox 34 Stepcast suspension fork, able to handle more difficult descents.

The lightest Reserve MTB rims yet make the new Blur roll. Reserve 28XC wheels feature a shallower and wider rim bed measuring 28mm on the inside and weigh 385g per rim, or 1367g for a full wheelset, with DT180 hubs, valves and tape adhesive.

There is no weight limit for the rider and the Blur and 28XC rim models are backed by Santa Cruz’s lifetime warranty. Small to very large sizes as well as C and CC carbon options are available.
