Shimano 105 R7120 Hydraulic Brake and Gear Levers
The lever design brings better control to a wider variety of riders. The SHIMANO 105 R7120 DUAL CONTROL LEVERS feature a revised lever position and bracket shape developed using data from a broad study of different hand shapes. That’s combined with the all-condition confidence of hydraulic disc brakes and the quick and intuitive shifting cyclists expect from SHIMANO 105.

Shimano 105 FC-R7120 12-Speed Chainset
The chainset features an attractive aluminium crank with hollow arms for lightweight, rigidity, and durability. The crank arms offer an optimized balance between lightweight and efficiency. The crank, formed with hollow aluminium 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.

Shimano 105 12-speed Braze-on Front Derailleur
The SHIMANO 105 12-speed front derailleur features lighter front shifting, smooth and natural shift action, and SHIMANO toggle link construction with an optimized cage design that is seamlessly compatible with disc brake road bikes.

Shimano 105 Flat Mount Hydraulic Brake Caliper
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. Please note, rotors are not included.

Shimano Ultegra BB60 Threaded Bottom Bracket
The groupset uses an Ultegra bottom bracket designed for a 68/70 mm shell width. The bottom bracket features reliable Shimano bearings and seals, to give the component a long service life.
