ChatGPT giver mig nedenstående resumé fra videoen :-) En del af årsagerne har med vægtfordelingen eller positionering at gøre.
Handlebar Width: Bikes often come with handlebars that are too wide, leading to pressure on the ulnar nerve and reduced circulation.
Excessive Reach: Overreaching to the handlebars puts excessive pressure on the hands, causing numbness.
Saddle Position and Tilt: Incorrect positioning or excessive tilt of the saddle can lead to sliding forward, placing more weight on the hands.
Saddle Height: Too high a saddle can cause the rider to reach forward excessively, contributing to numbness.
Saddle Selection: Choosing the wrong saddle in terms of width or shape can lead to improper weight distribution and increased pressure on the hands.
Crank Length: Using crank lengths that are not suited to the rider's height can affect weight distribution and lead to numb hands.
Adjustments for Comfort: The video suggests various adjustments, such as altering handlebar reach, saddle setback, and the control location on the handlebar, to relieve pressure on the hands.
