Description

Shimano 105 Di2 FD-R7150 12 Speed 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.

Shimano 105 Di2 RD-R7150 12 Speed 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.

Shimano 105 CS-R7101 12 Speed Cassette 11-34 or 11/36

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.

Disc Brake Caliper

Disc brakes optimized for road riding

With proven hydraulic braking technology, the new SHIMANO 105 calipers feature the SHIMANO Flat Mount System and its low-profile design that is ideal for road bikes. 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.

2 x Shimano 105/SLX SM-RT70 Disc Rotors 140mm 

SLX - CENTER LOCK - Disc Brake Rotor - ICE TECHNOLOGIES - 140 mm

SLX disc brake rotors deliver powerful and consistent brake performance for all riding conditions. The ICE TECHNOLOGIES FREEZA rotor significantly reduces heat build-up in the brake system to ensure consistent high performance braking even on the steepest downhill stretches. SHIMANO's CENTER LOCK mounting system makes installing and removing rotors quick and easy thanks to the spine mount and lock ring design.

Shimano 105 FC-R7100 12 Speed Crankset

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.

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.

Shimano EW-EC300 Charging Cable 12 Speed

The new EC300 charging connector is designed specifically for Shimano's 12-speed Di2 road drivetrains. Connected via the rear derailleur, it is also compatible with Shimano power meters.
