5.3 Definition of Tampering and Recommendations
Modifications to any part of your bike, such as the fork or frame, may make that part or the entire bike un-
safe. A poorly installed or modified component can increase the stress on all other parts, greatly increasing
their chance of failure. Modifications can also adversely affect the handling of your bike, resulting in loss of
control, falls and serious injury. Please do not add, remove, or modify parts of your bike in any way before
consulting with a trained bike technician. We recommend you consult with us at before you make modifica-
tions or add parts, in order to confirm their safety and compatibility with your bike.
