Speed Rohler
idworx Speed Rohler – Premium Gravel Bike with Rohloff E14 Solo Hub
Robustness Meets Electric Precision.
An uncompromising gravel bike for long distances and great adventures: The robust aluminium frame of the Speed Rohler combines high stiffness with a balanced, dynamic geometry – for precise handling, smooth running and pure riding enjoyment on asphalt, gravel and beyond.
The brand-new Rohloff E-14 Solo delivers precise electronic shifting, outstanding reliability and minimal maintenance. Its long battery life perfectly matches the Speed Rohler’s philosophy: ride for many kilometres without having to worry about the technology.
Our lightweight DaFork Carbon comes as standard, providing precise steering and a high level of comfort. For maximum independence on long tours, the Speed Rohler can optionally be equipped with a plugless SON 28 hub dynamo. This allows you to generate power for your smartphone, navigation device or power bank while riding – even far away from power outlets and charging facilities.
Robust technology. Minimal maintenance. Maximum independence. Ready for every road.

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.
