[Description] For example, I cannot fully extend or flex my fingers or thumbs, and my grip strength and dexterity are greatly reduced. I cannot hold a pen or type on a keyboard, and I cannot feed myself or get dressed without assistance. Shifting, braking, and maintaining an adequate grip on the bars. Adaptations. (1) I use electronic shifters mounted horizontally to enable me to shift with knuckles rather than fingertips, (2) the pulling force required to fully engage the two rear disc brakes was too much for me, so I have repositioned the rear brake lever to allow me to push on the lever rather than having to pull on the lever, (3) "winged" grips.
