CHAPTER 2: HANDLEBAR EXTENSION / RISER INSTALLATION
WARNING! Aerobars are attached to the front of your bicycle, and as a result, proper and secure installation is critical. Improper
installation or adjustment may result in damage to the bicycle or its components or in an accident which can cause serious injury or
death.
WARNING! Aerobars can require riding positions that are new or different to many riders, which may cause you to lose control and fall.
Continue to look forward while riding and not down towards the ground. We advise that you practice using these aerobars in a low traffic
area to become accustomed to any changes in the steering or handling of your bicycle.
