Shimano’s new 105 R7000 groupset ascends to the ranks of its more expensive siblings, now that the Japanese component giant has added dedicated hydraulic disc brakes, revised shifters and a host of other mechanical features.
However, these upgrades didn’t come by way of mere trickle-down economics, rather the new 105 was closely developed alongside its Dura-Ace and Ultegra forebears, resulting in a groupset that shares many of the same attributes as Shimano’s more costly groupsets.
In addition to disc brakes, the new 105 also gets redesigned shifters that mimimic the same ergonomic features as the company’s more expensive Ultegra groupset, such as expanded reach adjustment. Moreover, in the case of the hydraulic levers, Shimano offers an altogether separate version that’s more compact called “R7025”, which allows for an even closer position to the handlebar in order to assist riders with smaller hands.
Shifting for the new 105 has also been improved, wherein Shimano has reduced the amount of “throw” in each lever, along with a toggle-design front derailleur that limits the amount of “force” necessary to actuate shifting, while a new integrated cable port ensures optimal “tension”.
As a result, Shimano was able to remove the need for in-line cable adjustors, while the Shadow rear derailleur provides more efficient shifting through the gears, while also keeping the derailleur more inbound toward the cassette and out of the way of objects.
In addition to more stopping power and precise shifting, the new 105 also receives Shimano’s latest Ultegra RX clutch rear derailleur that’s designed to provide extra chain security on rough roads.
Lastly, the handsome new silver or black finish 105 groupset finally gets treated to a semi-compact 52-36t crankset, along with choices of 11-30t and 11-34t cassettes when paired with the optional long-cage rear derailleur.
According to Shimano, the new 105 R7000 will be available starting in June, with pricing for the caliper brake version starting around $745.00 and $1130.00 for its disc brake counterpart.

Employing the latest technology from DURA-ACE R9100 and ULTEGRA road components, Shimano 105 R7000 delivers added versatility and improved ride performance for a wide spectrum or road cyclists. Featuring refined ergonomics, ST-R7000 shift levers match the slim look and feel of Ultegra R8000 and R8020 while the addition of the RD-R7000-GS derailleur and 11-34T cassette expand gear ranges. The biggest news for Shimano 105 is the addition of hydraulic disc brakes with Shimano’s leading disc-specific features to the series lineup. New flat-mount BR-R7070 calipers are compatible with ICE TECHNOLOGIES pads and SM-RT70 rotors (including a new 140mm size) to offer the most capable Shimano 105 group yet.
The FC-R7000 HOLLOWTECH II Crankset delivers optimum power transfer, balancing weight and efficiently without sacrificing stiffness. Shimano’s range of Rider Tuned crankarm and chainring combinations expands with the introduction of a new 160mm crank arm and 50/34t ring option.
CS-R7000 and CS-HG700-11 Cassettes further expand gearing choices
The R7000 cassette features an increased range of high-performance gearing combinations while the new 11-34T CS-HG700 cassette further expands gearing options for a wide variety of terrain. Designed to fit both MTB- and road-specific (with spacer) wheelsets, the 11-34T gear combination provides mixed terrain riders more wheelset options than ever before.
Shimano 105 Series new hydraulic disc brakes offer all-conditions control
Utilizing Shimano’s lightweight and sleek flat mount design, the BR-R7070 Hydraulic Disc Brake Caliper features premium stopping power and aerodynamics for road applications. The new SM-RT70 rotor offers ICE TECHNOLOGIES construction for excellent heat management for confident performance on the longest descents.

Shimano’s legacy of industry-leading rim brake performance continues redesigned Dual-Pivot and Direct Mount models feature new technologies and sleek designs, resulting in improved stopping power and efficiency with clearance for 28C tires.
Refined Dual Control Lever ergonomics and a new small hand option for better control and improved precision
Shimano 105 ST-R7000 and R7020 feature redesigned internal shift units for slimmer, more ergonomically shaped control levers that match the design of Ultegra R8000 and R8020. Increased reach adjustment of up to 15mm provides more control and reliable performance in all conditions for both mechanical rim brake and hydraulic disc brake options. The new ST-7025 Hydraulic Dual Control levers offer the same features as ST-7020, but the reach starts 4mm closer and the lever blades allows riders with small hands to comfortably and securely brake without rotating their hands forward to grab the levers.
