Isaac Torus Xplore GRX610/RX820 2x12 gravel bike Blast Bronze

Description

Isaac Torus Xplore GRX610/RX820 2x12 gravel bike Blast Bronze is a 2026 model-year gravel bike focused on endurance riding, fast gravel transfers, and bikepacking. The spec is built around a carbon frame and a Shimano GRX 2x12 drivetrain, with an emphasis on a wide gear range and compatibility with modern standards. In performance terms, it’s a configuration aimed at experienced riders who care about efficiency on long routes as well as practical readiness for multi-day gear.

Frame and geometry

At its core is an Advanced Carbon Tech Triad 40 carbon composite frame paired with an Advanced Carbon Tech Dual 30 carbon fork; the manufacturer states an endurance-oriented geometry designed for long hours in the saddle. The frame features semi-integrated cable routing and an asymmetrical rear triangle to increase clearance at the chainring and reduce the risk of chain contact with the frame off-road. For bikepacking, there are mounting points on the top tube, down tube, seat tube, and fork, and it also includes mounts for fenders. Maximum tire clearance is 45 mm (frame and fork), and the axle standards are 12×100 mm front and 12×142 mm rear; the head tube is tapered (1 1/8"–1.5") with a Token A-Box headset. Specific reach/stack figures or chainstay length are not provided in the supplied materials.

Components

The drivetrain is based on the Shimano GRX gravel group in a 2×12 setup: Shimano GRX FC-RX610 cranks with 46/30 chainrings, a Shimano GRX FD-RX820 front derailleur, and a Shimano GRX RD-RX820 rear derailleur. The rear range is handled by a Shimano CS-HG710 11–36T cassette and a Shimano CN-M7100 chain; the bottom bracket is Shimano SM-BB72-41B for BSA threading (68 mm). Braking is handled by Shimano GRX BR-RX400 hydraulic disc brakes controlled by Shimano GRX ST-RX610 levers, with Shimano RT-CL800 160 mm rotors front and rear and Center Lock mounting. The DT Swiss G1800 wheelset is tubeless ready; the rim is hooked, with a height of 42 mm and an internal width of 24 mm (external 28 mm), fitted with Goodyear Connector TLR 700×45C tires. The cockpit consists of Pebble Competition alloy handlebars (400 mm, reach 78 mm, drop 125 mm, flare 16°) and an 100 mm alloy stem (-8°) with Isaac Momentum bar tape; the saddle is a Surface Powerbox and the seatpost is 27.2 mm carbon with 10 mm setback.

Ride characteristics

The endurance geometry and carbon frameset aim for stability at higher speeds and reduced fatigue on long gravel stretches, helped by the 27.2 mm seatpost, which typically allows more compliance than larger diameters. 700×45C tires on rims with a 24 mm internal width provide support in corners and allow lower pressures, which matters for traction on rough surfaces and for loaded bikepacking. The combination of 46/30 chainrings and an 11–36 cassette broadens the usable range from faster road riding to easier gears for longer climbs. DT Swiss G1800 wheels in tubeless setup support practicality off-road (reduced puncture risk and the ability to fine-tune pressure for the surface).

Who it’s for

Isaac Torus Xplore is designed for experienced riders who want a gravel bike with an endurance fit and full bikepacking readiness (mount points, 45 mm clearance, fenders). Compared with purely race-focused gravel bikes with more aggressive geometry, it prioritizes long-distance comfort and versatility while retaining modern standards (tapered steerer, thru-axles, Center Lock).
