Guerrilla Gravity's Gnarvana is proof that inhouse carbon-fibre frame design can deliver great value.
The Coloradoan mountain bike brand’s latest model targets committed enduro riders. If features 160mm of rear suspension travel and rolls 29er wheels, thereby offering a powerful combination of terrain damping suspension action and obstacle rollover ability.
Like all other Guerrilla Gravity frames, the Gnarvana pairs a carbon front triangle with an aluminium rear end. Guerrilla Gravity uses an advanced resin to set its carbon-fibre, which is claimed to be 300% more impact resistant than most conventional composite frames.
The Gnarvana is being offered in three frame sizes and they all feature very progressive geometry. With a 63.7-degree head angle, Guerrilla Gravity’s new 160mm 29er is among the slackest production mountain bike frames you can buy, with a single-crown fork.
Reach numbers are slightly less radical, with the mid-sized Gnarvana totalling 460mm. Guerrilla Gravity does allow all its customers to adjust reach by 10mm with the brand’s GeoAdjust headset.
To ensure the required rear-end stiffness to complement Gnarvana’s impressive suspension and geometry numbers, it has a 148mm Boost axle spacing and 3mm drive side offset. Those 3mm help create clearance for large-volume tyres and specific dishing when building wheels on the 148mm hub standard.
Riders who frequent muddy conditions will be heartened by the presence of threaded bottom bracket and with the ability to fit 30.9mm seatposts, you'll have a huge range of the latest dropper posts to choose from.
One of the cleverer frame details present on Guerrilla Gravity’s new Gnaravna is its external cable routing. Although internally routed cables yield a wonderfully clean look, they can be very bothersome to replace or adjust.
Guerrilla Gravity has found a great solution but using a cable gutter, which is covered with a bolt-on panel, applied to the non-drive side of its Gnarvana’s downtube. The result is a clean aesthetic, with a semi-hidden set of cables, which are easily accessible for maintenance when required.
The Gnarvana is set to retail for $2,195 as a frame only option, whilst Guerrilla Gravity will offer builds starting at $3,895 and peaking at $6,395
