Description

Some parts of this page are translated automatically, so please excuse any imperfections.

Isaac Torus Xplore GRX825 Di2 2x12 gravel bike Blast Bronze is a carbon gravel bike focused on endurance riding, fast gravel transitions, and bikepacking. The Shimano GRX Di2 2x12 drivetrain and DT Swiss G1800 wheelset place it in a higher performance category where precise shifting, stability, and practical readiness for long routes matter. In practice, it’s a versatile platform for riders who mix tarmac, gravel, and rougher farm roads and want electronics and wider tires without compromising on gearing.

Frame and geometry

The frame is made from Advanced Carbon Tech Triad 40 carbon composite and the fork is Advanced Carbon Tech Dual 30, engineered to combine pedaling stiffness with vibration damping on gravel. The manufacturer cites an endurance-tuned geometry for long rides and stability at higher speeds, while the frame uses semi-integrated cable routing and a Token A-Box headset. For added practicality on multi-day trips, there are mounting points on the fork, downtube, top tube, and seat tube, including the option to fit fenders. Tire clearance is rated for max. 45 mm, and thru-axles are the 12×100 mm standard up front and 12×142 mm at the rear, with a tapered steerer tube 1 1/8"–1.5".

Components

The drivetrain is built around electronic shifting Shimano GRX Di2 2×12 with Shimano GRX ST-RX825 levers, a Shimano GRX RD-RX825 Di2 rear derailleur, and a Shimano GRX FD-RX825 front derailleur. The Shimano GRX FC-RX820 crankset runs 48–31T chainrings, and the Shimano CS-HG710 11–36T cassette broadens the gear range for steeper climbs as well as fast road sections; the bottom bracket is threaded BSA with a Shimano SM-BBR60 unit and a Shimano CN-M8100 chain. Braking is handled by hydraulic disc brakes Shimano GRX BR-RX820 with Shimano RT-CL800 160 mm rotors front and rear and Center Lock mounting. The wheels are a DT Swiss G1800 wheelset with hooked rims, a 42 mm rim depth, and 25 mm internal width; Goodyear Connector TLR 700×45C tires are tubeless-ready. The cockpit uses aluminum Pebble Competition handlebars (400 mm, reach 78 mm, drop 125 mm, flare 16°) and an Isaac stem (100 mm, -8°); the saddle is Surface Powerbox and the seatpost is a carbon 27.2 mm.

Ride characteristics

The combination of the Triad 40 carbon frame, carbon fork, and 700×45C tires is aimed at efficiency on flat terrain while also damping vibrations on rough gravel, helped further by the slimmer 27.2 mm seatpost diameter. The endurance geometry and wider tire profile support stability on descents and at higher speeds on gravel, while 12×100/12×142 thru-axles increase tracking confidence under braking and through corners. Electronic GRX Di2 maintains shifting precision even under load, and the 48/31 double chainset paired with an 11–36T cassette provides tighter gear steps for sustained tempo riding as well as climbs with luggage.

Who it’s for

Isaac Torus Xplore is intended for experienced riders who want a gravel bike for endurance and bikepacking without limitations in gear range and with the benefits of electronic shifting. Compared to typical 1× gravel setups, it offers broader usability on mixed routes (tarmac/gravel) thanks to 2×12, while still keeping room for 45 mm tires and mounting points for gear.
