Rock oPinion Ti
idworx Rock oPinion Ti – High-End Titanium All-Mountain Hardtail with Pinion Gear Box
The idworx Rock oPinion Ti combines the full expertise of the idworx off-road concept with cutting-edge bicycle technology to create one of the most capable all-mountain hardtail bikes available today. Built around a premium titanium frame and equipped with the high-performance Pinion C1.12 gearbox system, this bike delivers maximum durability, minimal maintenance, and outstanding off-road performance.
At its core, the Rock oPinion Ti is designed for riders who want to fully immerse themselves in the riding experience. Thanks to the intelligent idworx Evolution geometry, the bike and rider feel like one unit, allowing for precise handling, natural control, and maximum focus on the trail. This makes it an ideal choice for demanding mountain biking, technical off-road trails, and long adventure rides.
One of the key strengths of the Rock oPinion Ti is its extremely low-maintenance design. Every component is selected to ensure long-term reliability and reduce mechanical effort, making it a perfect companion for intensive use in all conditions. The result is a bike that performs consistently—even on the most challenging terrain.
The bike now comes standard with high-performance Shimano XT 4-piston brakes, providing powerful, controlled braking and maximum safety on steep descents and technical
trails.
For riders seeking further customization, the Rock oPinion Ti offers a range of premium upgrade options. These include ultra-light and stiff idworx DaRim LaW carbon rims for improved steering precision, grip, and comfort, as well as the idworx GoMax Carbon rigid fork for reduced weight and enhanced responsiveness.
Additional options such as a Vario seat post, the Pinion P1.18 gearbox (offering closer gear steps and a wider range), or the CDX Gates Carbon Drive belt system further expand the bike’s versatility and performance potential.
The Rock oPinion Ti combines sporty, agile handling with exceptional stability and safety on technical trails. Its balanced geometry, high-end materials, and carefully engineered components make it a top-tier choice for riders seeking a premium titanium all-mountain hardtail with maximum performance and minimal maintenance requirements.

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.
