The sensation of electricity flowing from my shoulder to the elbow and fingers is horrible. I need to know what is the maximum extension I can do and which parts I need to do it. I had invest a lot of money on my bike on customization and I love it! I don't want to change it (last alternative to contemplate). Also if I can use a 28mm instead of a 23mm tire on the Mavic Axium rims. Thank you in advance for your help guys!
