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.
