Frog Legs is the world-wide expert in wheelchair suspension. with over 14 years experience we manufacture the original and best wheelchair shock absorbing caster forks available. Attention to even the smallest detail has resulted in the lightest, strongest, most functional high-resilient urethane caster wheels developed specifically for wheelchairs,


In 1994 Frog Legs' founder Mark Chelgren befriended members of a quadriplegic rugby team. Having come from a technology progressive, crank head bicycle environment he began working with the athletes.  He built a suspension system to prevent muscle spasms,  back pain and other injuries that come from a rough ride or being pitched from your chair to the pavement.
