We drew on everything we’ve learned from years of crafting the highest-quality carbon full-suspension bikes and added the super-efficient Superlight™ suspension to create a World Cup-winning XC race bike. While the Blur isn’t guaranteed to make you a race winner, being the lightest full-suspension carbon XC bike we’ve ever made might be the difference between contending for first place or just crossing the line.

A SUPERLIGHT™ FULL-SUSPENSION XC BIKE  -  Cross-country racing isn’t just a power lap around the park anymore. The courses are challenging, and the competition is fierce. Superlight™ provides traction to avoid wobbles while keeping overall weight down. By reducing the number of moving parts, bearings, and linkages, we saved 289g compared to the previous Blur.

A FAIR ADVANTAGE  -  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.
