Gran Rohler
idworx Gran Rohler – Premium Touring Bike with Rohloff E14 Solo Hub
Robustness Meets Uncompromising Touring Capability.
The new idworx Gran Rohler combines the dynamic character of a gravel bike with the equipment of a fully equipped touring bike. Its robust aluminium frame combines high stiffness with a balanced, dynamic geometry – for precise handling, smooth running and pure riding enjoyment, even when the road has long since ended.
The brand-new Rohloff E-14 Solo combined with a drop bar provides precise electronic shifting and comfortable gear changes in every riding situation. Together with proven Rohloff technology, it stands for high reliability, minimal maintenance and long battery life – perfect for long journeys and many thousands of kilometres.
The Gran Rohler comes fully equipped for extended tours straight from the factory: a SON hub dynamo, powerful LED lighting, mudguards, luggage rack and many other carefully considered idworx details make it a reliable companion for long-distance travel and everyday use. The hub dynamo provides an independent power supply for the lighting and can also generate energy for your smartphone, navigation device or power bank while riding with the optional SON Ladelux Headlight.
Get on. Ride off. Keep going.
The Gran Rohler is ready for the great journey.

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 EBB Long Life II
Eccentric bottom bracket with integrated, rustproof ball bearings. The only bottom bracket on the market with bearings that are actually sized to suit the load for an extremely long service life and optimal smooth running even under the highest loads. It also offers the option of installing our idworx Hesling chain case. Suitable for all idworx Rohloff models with eccentric bottom bracket for adjusting the chain play. Our idworx EBB-LL II is also compatible with Gates Carbon Drive belt drive.
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.
