Battery BT-DN300 -

The new DN300 battery features the same waterproof design that Di2 users have loved for generations. Now with 3 ports, it delivers stable power to Shimano's 12-speed road derailleurs and shifters (if a fully wired option is selected).

With the same size as its predecessor, the slim DN300 battery can be housed inside seat posts or frames ensuring a clean aesthetic. Now with 3 ports, the DN300 simplifies wiring to front and rear derailleurs, supplying stable power at all times. The third port is for riders who seek the redundancy of Shimano's 12-speed Di2 wired option.

More compact and lighter than ever, the R7170 brakes offer wide pad clearance for easy wheel removal and quiet performance as well as one-way bleeding for easy, clean maintenance.

R7100 Cassette

A 12-speed cassette range that brings versatility to any rider or road

From sprinting on the flats to climbing steep inclines, the 11-34T cassette has you covered. It is compatible with both SHIMANO 11-speed and 12-speed FREEHUB bodies.

R7100 Chainset

An attractive aluminum crank with hollow arms for lightweight, rigidity, and durability

The newly designed crank arms offer an optimized balance between lightweight and efficiency.

The crank, formed with hollow aluminum technology, is anodized with a beautiful gloss black anodized finish, giving it a luxurious look.

The resin ribs on the back of the chainrings are SHIMANO 105's unique structural design that achieves both thorough weight reduction and crisp shifting performance.

R7150 Di2 Front Derailleur 

Di2 brings precise, coordinated front shifting to SHIMANO 105

SHIMANO Di2 electronic shifting lets you change from the big to small chainrings, or vice versa, whenever you like while minimizing the risk of a dropped chain. Similarly, you can perform rear shifts without the need to trim the front derailleur to avoid chain rub.

Full- and semi-synchronized shifting functions can be selected using the E-TUBE app. With digitally accurate electronic shifts and coordinated communication between shifters and derailleurs, the new SHIMANO 105 front derailleur offers the best shifting you've ever experienced.

R7150 Di2 Rear Derailleur 

A new level of performance for SHIMANO 12-speed road rear derailleurs

Wide 36T-compatible 12-speed Di2 rear derailleur.

Receiving the wireless shifting signal from the shift lever, the SHIMANO 105 rear derailleur completes a shift in the blink of an eye with its high-performance motor and optimized link structure.

This is the hub of the Di2 system, with the charging port, indicator LEDs, adjustment switches and more integrated into a compact package. A low-profile design reduces damage from contact and falls.
