Santa Cruz Blur 4 C GX AXS TR Transmission RSV Kit

With its trim frame and super-efficient Superlight™ suspension, the Santa Cruz Blur 4 C GX AXS Transmission TR RSV has shed 289 grams off of the previous model. Santa Cruz reduced the amount of moving parts, bearings and linkages to ensure that the rider's energy is translated into forward thrust.

For the "TR" variation, the fork is bumped up to 120mm instead of 100mm. The slightly increased head tube angle and longer reach of the fork and front tire improves the rider position for more stable descents. The RSV version also features Reserve carbon rims.

"Anti-Squat" plays a big role in the Blur's efficiency as well: The frame and rear suspension employ a leverage curve to provide support and control to reduce the influence that the chain tension has on the suspension. This prevents the dreaded "squat", where the rider's pedaling energy compresses the suspension rather than propelling the bike forward. This also allows the rear tire to have more traction and sensitivity while both climbing and descending. 

The anti-squat characteristics of the frame/suspension interface also allow help overcome the influence of the rider's body weight on the suspension. Bounce, pedal bob and squat are all reduced, and speed is increased. Win, win!
