Important safety information
Important safety information
Do not disassemble or modify the product. This may cause the product to not operate correctly, and you
may suddenly fall and be seriously injured.
Downhill bicycle riding and freeriding are inherently dangerous activities. It is strongly recommended that
riders wear protective head and body gear and perform thorough safety checks of their bicycles before
riding. Please remember that you are riding at your own risk and that you have to consider your
experience and your skills very carefully. There is a risk of being involved in an accident that can result in
a serious injury or even death.
Check that there are no cracks in the cranks before riding the bicycle. If there are any cracks, the crank
may break and you may fall off the bicycle.
Be careful not to let the hemming of your clothes get caught in the chain while riding. Otherwise, you
may fall off the bicycle.
Be careful not to touch the teeth of chainrings. There is a danger of injury.

Use a neutral detergent to clean the crank and the bottom bracket. Using alkaline or acidic detergents may
cause discoloration.
If pedaling performance does not feel normal, perform an inspection again.
Do not wash the surrounding area of the bottom bracket with a high-pressure washer.
The gears should be periodically washed with a neutral detergent. In addition, cleaning the chain with neutral
detergent and lubricating it can be an effective way of extending the life of the gears and the chain.
The cuffs of your clothing may get dirty from the chain while riding.
Products are not guaranteed against natural wear and deterioration from normal use and aging.
For maximum performance we highly recommend Shimano lubricants and maintenance products.
