Campagnolo Rims Score Big Victories!
In only three years since their introduction, Campagnolo rims have already made their mark on the sport. Earlier this year Robe rto Gaggioli of the Pepsi-Fannini team won the Core States Pro Championships on Campagnolo Omega clincher rims. In fact, two of the lead ing pro team s in Italy are racing and winning on our new clincher rims. proof positive of their superior weigh t and strength characteristics. On the continent, Campagnolo rims continued to carry Europe's best pros to victory racking up an impressive fi rst, second, and third along with King of the Mountains and team classification in this year's Tour de f rance. Then, only a few short wee ks later Maurizio Fondriest ro lled to victory in the World Championships a ll Campagnolo rims to further establish the m as the choice of champions. The world's best riders including Lemond. Delgado and f ondriest choose our rims because they're 10% lighter and 40% stronger than any other rims made. Their patented double position eyelets ensure agai nst spoke breakage and their unique cross sections and surface treatments give them unparalleled reliability. In addition, Campagn olo rims offer the advantage of tremendous time savings during assembly. Many shops building with Campy rims have remarked how easy they true up tha nks to their roundness. To ensure this, each Camgagnolo rim is inspected with a sophisticated Vision Camera System before it ever leaves ou r factory. So if you haven't tried our rims yet, we urge you to fi nd out for yourself what makes them the overwhelming choice of the world's best riders.
