It took a few years, but Shimano finally unveiled its version of the clutch derailleur in the Ultegra RX earlier this week. On Monday, we took an in-depth look at both the Ultegra RX derailleur and Shimano’s 105 groupset.
Clutch derailleurs are popular in cyclocross, but they also have an application this time of year during the cobbled classics such as the Tour of Flanders and Sunday’s Paris-Roubaix. Shimano produced this video along with the Trek-Segafredo team that talks a bit more about the new Ultegra RX derailleur and why its appealing long before ’cross season arrives.
