The Shimano 105 Di2 Shadow RD-R7150 12-speed rear derailleur offers the fastest and most precise shifting function at an attractive price.
105 has never been as versatile as the current version.
Triggered by the wireless shift signal from the shift lever, the extremely powerful motor of the SHIMANO 105 rear derailleur, in conjunction with the optimized link structure, carries out a shift within a fraction of a second. The rear derailleur is the heart of the Di2 system, combining the charge connector, LED indicators, adjustment switch and more in one compact package. The low profile reduces the risk of damage from contacts and falls.
