Santa Cruz Bicycles Blur 4

While the Blur 4 is designed as a high-efficiency cross-country race bike, its geometry is versatile enough for aggressive trail riding. It excels on long rides where speed and climbing efficiency are priorities, but it remains stable and capable on technical descents.

The frame accommodates tires up to 2.4 inches wide. This provides a good balance between rolling efficiency for XC racing and enough volume for traction on rougher terrain.

The Blur 4 features a 73mm threaded bottom bracket. This is a significant advantage for home mechanics, as it simplifies maintenance and is generally more reliable and creak-free than press-fit alternatives.

The bike is equipped with 110mm of travel in the front and 107mm in the rear. This short-travel setup is optimized for maximum pedaling efficiency and quick acceleration on varied terrain.

Yes, the frame includes multiple water bottle mounting locations. This is a practical feature for long-distance rides or races where carrying extra hydration without a pack is essential.

The Blur 4 is built exclusively around 29-inch wheels. This size is standard for modern cross-country bikes, offering superior rollover capability and momentum maintenance on technical trails.
