ARRIVAL OF THE FITTEST

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.

FAQs

Blur is the model name, Superlight™ is our new pivot system employed on the Blur.4. You can read more about that HERE

We offer the Blur.4 in 2 travel options: 'XC' - 110mm travel front and 107mm rear travel. This option uses a 40mm stroke rear shock. 'TR' - 120mm front and 115mm rear travel. This option uses a 45mm stroke shock. All Blur.4 frames accommodate both shock sizes.

Yes, there are a limited number of Blur.4 frame-only options available. Contact your local dealer for more info.

No, 29" wheels only, front and rear

On sizes M, L, XL there are three bottle mounts- two on the inside of the front triangle, and a third underneath the downtube. The small size does not have the third one underneath the downtube, but does have the other two.
