Shimano Dura-Ace 9270/GRX 825 Di2 Custom Gravel Racer Groupset Description:

The Shimano Dura-Ace 9270/GRX 825 Di2 Custom Gravel Racer Groupset combines select components out of Shimano’s flagship Shimano Dura-Ace and GRX 825 drop-bar catalog to deliver a very lightweight, gravel race ready 2×12 speed groupset. This groupset has a rear derailleur equipped with Shadow RD+ chain retention technology, a front derailleur that is optimized for lower gearing and clearance for wider tires, an expanded gear range that makes it very easy to find the right gear for any condition, and ergonomic shifter hoods that provide a comfortable and secure hold anywhere the rider decides to go. The wireless Dura-Ace Brake/Shift Levers eliminate the wires of previous Shimano Di2 road shifters for a cleaner cockpit, and the operation of the shifting paddles can be fully customized through Shimano’s E-Tube Project app; additionally the shift/brake levers are adjustable so they can be positioned for anyone to comfortably reach the controls from the top of the hoods and from the drops of the handlebars. Linked up to the ergonomic brake/shift levers are powerful, easily modulated BR-R9270 flat mount disc brake calipers which are also very quiet, consistent, and deliver powerful braking thanks to generous pad to rotor clearance and the multi-piece Dura-Ace RT-CL900 Centerlock Disc Rotors featuring Shimano’s ICE Technologies w/ FREEZA. Add in incredible battery life and compatibility with a wide assortment of wheels and bicycles, and this groupset has everything needed to build up the ultimate lightweight gravel slayer.

Features:

• Combines Shimano’s lightest electronic (Di2) drop bar shifters and cassette with improved chain retention, tire clearance, and lower gearing to create an elite all-road groupset
• 2×12 speed drivetrain combines a wide gear range with smaller jumps between gears which makes it easier to achieve a pedaling cadence that delivers an optimal balance of efficiency and speed
• Raised hood peak and a longer hood body improves ergonomics, while subtle texturing improves grip in any weather condition
• Brake levers are equipped with Servo Wave for better modulation and lever feel, and the lever position can be adjusted to allow it to fit any hand size and rider preference
• GRX 825 front derailleur fits up to 48 tooth outer chainrings, can work with up to a 17 tooth size difference between the outer and inner chainrings, and has extra clearance for wider tires
• GRX 825 rear derailleur is equipped with a clutch style drivetrain stabilizer that can be switched on for greater chain retention and less chain slap on rough roads and trails, and then turned off on smooth surfaces for faster shifting
• 12-speed titanium Dura-Ace cassette is incredibly light and durable, and fits on any HG Road 11/12 speed compatible rear hub and/or wheel
• BR-R9270 flat mount disc brake calipers have a generous pad-to-rotor clearance for less brake rub and noise, and are equipped with finned brake pads that cool the pads to reduce brake fade
• Dura-Ace RT-CL900 Centerlock Disc Brake Rotor uses multi-piece construction and ICE Technologies w/ FREEZA to significantly reduce heat build-up for more consistent and powerful braking performance
• Groupset includes everything you need – except for the crankset, bottom bracket, and the EW-SD300 E-Tube Wires to connect the front and rear derailleur to the battery (all of which are dependent on the bicycle’s size/frame specifications and on user’s preference for fit)
