Discover the idworx oPinion Trekking Bike
The ultimate heavy-duty trekking bike with disc brakes and Pinion gearbox, designed for demanding tours, long-distance travel, and maximum reliability.
If you are looking for a premium trekking bike with outstanding durability, the idworx oPinion is built for exactly that purpose. Developed as the perfect companion for bikepacking, world travel, and trekking adventures with heavy luggage, it combines exceptional frame stiffness, powerful disc brakes, and the advanced performance of the Pinion gearbox system.
The oPinion is the direct evolution of the legendary All Rohler with Rohloff Speedhub and shares its renowned robustness, comfort, and long-term reliability—enhanced by the even wider gear range of the Pinion gearbox.
Built around an extra-stiff frame, the idworx oPinion ensures outstanding stability even under maximum load. Every detail is engineered for fully loaded trekking tours: from long-distance expeditions to demanding off-road adventures. To perfectly integrate the Pinion gearbox, the frame has been completely redesigned with special synchronously adjustable dropouts and an oversized thru-axle system for precise chain or belt tension adjustment.
As standard, the oPinion comes equipped with the 12-speed Pinion C1.12 gearbox, offering smooth shifting, low maintenance, and excellent efficiency. For riders seeking an even wider gear range, the 18-speed Pinion P1.18 gearbox is available as an optional upgrade.
The idworx oPinion is the perfect trekking bike for cyclists who demand uncompromising performance, maximum durability, and true expedition-ready engineering.

idworx Stress Reducer steering angle limiter
effectively prevents the front wheel from turning over and thus protects against damage to the frame, headlights or even the shift cables and brake hoses, which can occur due an accident or if the bike falls over.
idworx Long Life Chain Rings
The Long Life chain ring we developed at idworx made of hardened stainless steel with an uneven number of teeth together with the extra-hardened idworx KMC E1 ePT chain and the idworx Rohloff steel sprocket, makes for unprecedented longevity. In our oPinion models we even fit our Long Life chain ring back and front. Chain tension requires less frequent checks - a pleasing consequence of a more wear-resistant drive.
