The 2025 Viral Dérive was just updated with a few geometry refinements and design tweaks, including clearance for 29 x 2.6″ tires, size-specific crank lengths and bottom bracket heights, and more. Find all the details here…

First released in 2019, the Viral Dérive is a trail and bikepacking-ready titanium hardtail designed around a Pinion gearbox and a Gates belt drive. Neil reviewed the previous model last year and summarized its geometry as versatile and grounded, offering a ride quality that feels great loaded up with gear. To quote his review, “If I was to imagine the perfect bike built around the Pinion gearbox, I feel like the Dérive is it.”

Viral just announced the 2025 Dérive, which stays true to its adaptable beginnings but sees a number of small adjustments and design tweaks. The biggest change is that the geometry is fully dedicated to 29″ wheels, with clearance for 29 x 2.6″ tires. The previous model was compatible made with 27.5 x 3.0″ tires in mind, resulting in a higher bottom bracket to accommodate those tires. A true 29″ platform means a consistent fit and feel across the entire size run, and they’ve shortened the crank lengths on all sizes (V4: 165mm, v3: 160mm, v2: 170mm).

Another major change is the placement of the seat stays, which now wrap around the seat tube, allowing for full internal brake hose routing for a cleaner look. The 2025 Viral Dérive also took some cues from the brand’s drop-bar adventure bike, the Viral Wanderer, including the ability to run full internal wire routing for a dynamo rear taillight. Viral also outfit it with a titanium light mount designed to hold the Supernova TL3 Mini seatpost clamp taillight.

The complete offering features a selection of high-end components, including Chris King wheels and headset, a OneUp dropper post, stem, and handlebars, a RockShox Pike Ultimate or Viral Carbon Boost rigid fork, and SRAM Level Ultimate 4-piston disc brakes. The complete build costs $9,895 USD ($8,906 pre-order price) with a PIKE Ultimate fork or $9,405 ($8,465 pre-order price) with the Viral Carbon Boost Fork.
