Custom-built for each customer, the Lasher Sport All Terrian Beast Manual Wheelchair is lightweight (28.5 pounds) yet claims to be stable and nimble off-road, due primarily to its 12.5-inch front caster wheels and Spinergy rear wheels. All of the chair's components are machined out of aircraft-aluminum alloy. Standard features include tension-adjustable seating and backrest plus frog-leg shock absorbing caster forks; optional features include disc brakes, upgraded cushions/carbon seating, and various footrest options.
