The Eagle Has Landed — The Gravity Allrounder

The Onza Aquila 29" offers a great balance of aggressive tread and open areas for hardpack, loose and mixed soils. The tread design offers best rolling characteristics combined with high braking grip.

Soft Compound 50, a combination of a 50a rubber compound in the center and sticky 45a rubber on the side knobs, is the right choice for all gravity oriented riders looking for ultimate grip on rocks and roots.
