Since we saw the prototypes at Eurobike 2016, the Onza Aquila has seen a few tweaks to help get it through manufacturing. It’s been in gestation for a year, their longest development cycle for a tire ever. That’s partially because it needed a few small design tweaks to make it easier to produce, and partially because it’s their new Aaron Gwin signature tire…and Gwin was hands on with development.
The Aquila is a 1325g, wire bead 27.5×2.4 tire with their DH Casing your choice of super soft GRP 40a or RC2 45a/55a dual compound rubber. Those are the two versions (for now), with only the rubber compound differentiating the two.
Retail is $80-$85, and they’re tube type, but Aaron is riding them tubeless with sealant. They can’t officially recommend that, but if your race is only lasting a few minutes, well, go for it.
