The Shimano RS500 wheelset has undergone a complete transformation to the Shimano Ultegra WH-RS500. The RS500 has the appearance of a very chique wheelset and certainly not that of an entry-level model. Concerning the design, the RS500 fits better in the entire wheels assortment of Shimano. They did not only change the appearance, but the wheelset is also realised with a tubeless rim and tubeless valves to create a lower rolling resistance. With tubeless without inner tubes, you won't get a lot of punctures. You will get more comfort, if you add latex, because you can ride at a lower tyre pressure.
