WARNING
- READ THE REAR 12mm E-THRU TYPE I SYSTEM INSTRUCTIONS CAREFULLY BEFORE USE. IF YOU HAVE ANY QUESTIONS, ASK YOUR DEALER.
- The Rear 12mm E-THRU Type I system can be used in combination with a special frame and a special hub/wheel. If used in combination with any other frame or hub/wheel, the wheel may come off the bicycle while riding, resulting in serious personal injury.
- If the rear 12mm E-THRU Type I system is not installed correctly on the bicycle, the wheel may come off the bicycle while riding, resulting in serious personal injury.
- If the E-THRU lever is on the left side (rotor side) of the frame, make sure that the E-THRU lever does not interfere with the rotor. Also, make sure that the E-THRU lever does not come into contact with the frame, other parts, accessories, etc., or obstacles (such as bushes or rocks) while riding. If the E-THRU lever comes off due to contact with foreign objects, the wheel will come off and start rattling. In this case, contact the place of purchase or bicycle dealer. Riding a bicycle with a loose wheel may result in a fall and serious injury.
- Do not touch the disc brake rotor when handling the E-THRU system. Also, do not operate the E-THRU lever while the wheel is turning. The disc brake rotor is very sharp and touching it may result in serious injury.
- The brake calipers and disc brake rotor become very hot when the brakes are used. To avoid the risk of burns, make sure that they have cooled down thoroughly after riding the bicycle before handling the E-THRU system.
- Before installing the wheel, remove all foreign objects and dust from the hole at the fork end, the thread on the frame side, and the holes on the axle. Foreign objects and dust can prevent the E-THRU system from being installed correctly, and if the hub and axle are not installed correctly, the wheel may come off, resulting in serious injury.
