Today i went for a ride with my racer. I m noticing that when i get stuck in traffic i get this pain from my thumb to the back of my hand...could it be that my tendons are getting used yo the stress after almost 10 years of not using a bike? Or maybe i need to switch from clip ons to flat bar? Has any one fitted a flat bar on a racer? I love the clip ons and i think the problem is my wrist not the bike.
