idworx Rohler BLT – The Ultimate Aluminum Adventure Bike with Rohloff Gear Hub
The idworx Rohler BLT is a high-performance aluminum adventure bike designed for riders who want to explore the world both on-road and off-road. Built for demanding bikepacking trips, expedition cycling, and remote off-road adventures, this premium travel bike combines durability, low maintenance, and outstanding riding performance.
Based on the proven frame geometry of the popular oPinion BLT model and specially optimized for use with the legendary Rohloff gear hub, the Rohler BLT delivers a sporty and highly capable riding experience—even far beyond the beaten path. Its completely redesigned triple-butted aluminum frame offers exceptional strength, low weight, and long-term reliability, making it the perfect companion for serious adventure cyclists.
The newly developed aluminum frame features three bottle cage mounting positions, ideal for long-distance touring and bikepacking setups. In addition, the redesigned top tube significantly improves frame stiffness, ensuring better power transfer, stability, and control on rough terrain.
A key technical highlight is the idworx EBB Longlife II eccentric bottom bracket, which allows simple and precise chain tension adjustment. As the only bottom bracket on the market with bearings specifically dimensioned for high loads, it guarantees an extremely long service life, smooth operation, and maximum reliability—even under the toughest riding conditions.
The low-maintenance Rohloff gear hub is world-renowned for its durability, precision, and performance, making it one of the best drivetrain solutions for expedition bikes and adventure touring bicycles. Combined with the proven idworx off-road geometry, the Rohler BLT offers excellent handling, superior comfort, and confident control across all types of terrain—from gravel roads to mountain trails.
Available in frame sizes 46 cm, 51 cm, and 56 cm, the idworx Rohler BLT is built for cyclists who demand reliability, comfort, and performance without compromise.
Whether you're planning a bikepacking weekend, a remote gravel expedition, or a round-the-world cycling journey, the idworx Rohler BLT is engineered to handle every adventure—reliably, comfortably, and with true expedition-ready performance.

idworx Stress Reducer steering angle limiter
It effectively prevents the front wheel from turning and thus protects against damage to the frame, headlight or even the shift and brake cables, such as can occur due to a fall or the bicycle tipping 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.
