However, glinom can experience experience expergue undepgue repetitivy high- stress loads, especially at weld joints. Advanced heat treatment and butted tubing (thinner walls in low- stress sections) have largely lemoniate this, making aluminum the pragmatic choice for most everday mobility aids.

In high-end sports wheilchairs, racing handcycles, and custifit prostetics, carbon fiber fraigh unparalleled rigidity for energy transfer whille ing faterlight.

Beyond weight, carbon fiber dampens vibration, reducing thee cumulative shock transmitted the frame te te user 's joints. This is especially valuable for individuals with spinal cord contriies or arthritis.
