The GRIT Freedom Chair is conservatively balanced to make tipping over backwards unlikely, but some riders feel more comfortable with anti-tip bars installed. These attach to the chair to prevent it from tipping over backwards on steep hills. These are not recommended for all riders – they can get snagged on the trail and limit the range of obstacles you can traverse with the GRIT Freedom Chair. They easily attach to the chair with a screwdriver and an adjustable wrench. Each set includes two anti-tip bars, one for each side of the chair.
