oPinion Classic
Discover the idworx oPinion Classic
After our All Rohler Classic, it was only a logical step to introduce a Classic version of our oPinion as well. This model combines robustness, low maintenance and durability to create the perfect touring companion.
We have opted for a fixed specification, refined through our many years of experience, feedback from our idworx dealers and the hundreds of thousands of kilometres ridden by our customers:
- Pinion P1.18
- DaCover chain/belt guard
- Schwalbe Marathon Almotion Pro tyres in size 55–622
- DaBrace luggage rack reinforcement
- Angle-adjustable stem
- Riser bar
- Glossy Black – understated and timeless

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.
