105 Shadow design with Di2 technology, shifting is easy and precise – just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear The rear derailleur is now the brains of the system with wireless connectivity to the shifters. It acts as the point the system is charged, provides ANT connection to 3rd party devises and replaces the handlebar junction Button on the derailleur for Di2 operations, and LED light denotes synchronized shift mode, setting mode and charge requirements Sleek appearance with Low profile Shadow design construction reduces risk of damage in a crash Programmed automatic motion at the touch of a switch makes this derailleur quick, smooth and effortless to shift The removal of traditional mechanical cables in favour of electrical wires to the battery not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts Derailleur contains a saver (fuse) function, where the inner structure is protected from strong impacts High tolerance cold forged aluminium link plates and body construction is extremely light and durable Four self-lubricating micro-machined fluorine-coated link pivot bushings provide low-friction shifting 12-speed E-tube Di2 compatible Wide gear ratio compatible up to 11-36T FEATURES Compact design includes an integrated wireless unit, charger, switch LED status indicator Battery indicator Pairing Adjust mode, etc. Wider range capacity Max. low sprocket: 36T PRODUCT SPECIFICATIONS MODEL NO RD-R7150 SERIES SHIMANO 105 R7100 Di2 Series Color Series color Average weight 302 Remarks w/o Bracket spec. available Rear speeds 12 Top-normal spring type|SHIMANO SHADOW RD ✔ Mount|Direct attachment (conventional) ✔ Mount|Direct mount ✔ Max. front difference 16T Total capacity 41T Low sprocket|Max. 36T Low sprocket|Min. 34T Top sprocket|Max. 11T Top sprocket|Min. 11T Fluoric coated link bushings 4 Pulley|Teeth 11 Pulley|Sunken type pulley screw ✔ B-axle|Hollow axle ✔ B-axle 2|Hollow axle ✔ Di2 connectivity wired|Di2 shifting ✔ Di2 connectivity wireless|Di2 shifting ✔ Di2 connectivity wireless|Bluetooth® LE custom (*1)|Adjust mode information ✔ Di2 connectivity wireless|Bluetooth® LE custom (*1)|Di2 battery level ✔ Di2 connectivity wireless|Bluetooth® LE custom (*1)|Gear position ✔ Di2 connectivity wireless|Bluetooth® LE custom (*1)|SHIMANO STEPS data items (*3) ✔ Di2 connectivity wireless|Bluetooth® LE custom (*1)|Compatible with E-TUBE RIDE ✔ Di2 connectivity wireless|Bluetooth® LE custom (*1)|Compatible with E-TUBE PROJECT ✔ Di2 connectivity wireless|ANT private (*2)|Adjust mode information ✔ Di2 connectivity wireless|ANT private (*2)|Di2 battery level ✔ Di2 connectivity wireless|ANT private (*2)|Gear position ✔ Di2 connectivity wireless|ANT private (*2)|SHIMANO STEPS data items (*3) ✔ Firmware update by E-TUBE PROJECT ✔ SD50 port (pcs) 0 SD300 port (pcs) 1 SD50 connector (pcs) 0 SD300 connector (pcs) 0 LED for system status ✔ Charging port (pcs) ✔ Charging cable EW-EC300
