Take a look at the best of our trending stories from this week June 9, about the latest road bikes, tech, pro racing and more in the cycling industry. As full of ourselves as we are, this magazine can only be at its best when we make the effort to fill the pages with the bikes, products, places and people that reflect what the readers are interested in. To that end, we produce this “Reader Survey” annually, which helps provide your favorite cycling editors with a snapshot of who you are.
And sure, it will take a few minutes for you to fill out the questionnaire, but really, aren’t a few minutes spent with this worth the opportunity to win a free Shimano Ultegra-equipped Canyon Ultimate to dazzle all your friends with on the next group ride? ENTER HERE
