With the new Ultegra RX chain stabilizer derailleur Shimano is bringing adventure back to road riding. Whether you ride Di2 or mechanical the idea is to stabilize your chain over rough ground to reduce excessive chain movement and general ‘chain chatter’. Much like Shimano’s MTB derailleurs the On/Off switch can be found next to the upper pulley. When activated the rear derailleur pivot takes a firm hold to reduce excessive movement and noise. #RideShimano #UltegraRX
