Riding slow on my road bike

by gently engaging your core (if you have the control and proprioception) you can lessen the dead weight on your hands. this will then also allow your body to dissipate shocks more gently, so they are not concentrated in certain locations.

I will try to train my core, and put less weight on my hands. I have never had a very flexible and strong core, so it could be the key to solve the problem. I also couldn't find much information about this problem on the internet (maybe I'm searching worng). So thanks for the advice.
