The watchword here is ‘versatility’. On and On comes with multiple rack mounts and bottle bosses, making it the perfect packhorse for long-haul touring. The pared-back styling is also suited to faster hacks when time is equally lean, the slick lines achieved by routing all cabling through the frame.

Analysing data from our countless gravel-bike fitting sessions has enabled us to create optimal geometry. This ensures an efficient riding position on quicker spins, as well as day-long comfort on expedition rides. On and On can be easily sized, whether you’re a dedicated dirt vet or a keen, green debutant.

Handling is reliable on rough ground but relaxed on smoother surfaces. This is the ideal machine for riders who might be looking to upgrade their commuter but also have greater cycling ambitions; a machine, additionally, for those whose ambitions have no limits.

The fully integrated, carbon gravel frameset features the toughest, most rigorously tested carbon frame Pearson has produced. Lightweight and comfortable it offers exceptional durability, while integrated carbon bars have a 15-degree aero flare and a carbon stem. An aero seatpost features a straight-through, teardrop design.

The bike can be fitted with Shimano mechanical gearing, or electronic Di2 for seamless shifting. Flat mount, hydraulic disc brakes provide punchy stopping power regardless of conditions, while a dropped chainstay allows for greater tyre clearances. (On and On is adaptable for/up to 700 x 45 tyres.)

Available in two colours: Black Star (black, with slight metallic sparkle); and Stone (subtle tonic lacquer).
