Shimano 105 R7120 Disc – Top-Level Mechanical Shifting
The Shimano 105 R7120 Disc groupset is made for riders who value reliability and simplicity, without the hassle of charging batteries. With the Premium Mechanical Shifting System, you’ll enjoy crisp, precise gear changes – even under load, such as during climbs or sprints.
Powerful Control with Disc Brakes
This set comes with high-quality disc brakes, giving you powerful and predictable stopping power – essential for safety in traffic. Shimano has increased the clearance between the brake pads by 10%, making brake rub a thing of the past. This improvement lets you enjoy every ride without annoying noises or loss of efficiency.
Enhanced Disc Brake Technology
The aluminium 105 brake calipers are CNC-machined from two pieces and share technology with the top-tier Ultegra and Dura-Ace groupsets. With the increased brake pad clearance (also 10% more), they are better protected against rubbing caused by wheel wobble or heat deformation. At the same time, braking force is easier to modulate, giving you more confidence and control – even on long descents.
Advanced Technology
Shimano Shadow RD
The 12-speed rear derailleur uses Shimano’s Shadow RD technology, positioning the derailleur neatly under the cassette to protect vulnerable parts from damage during transport or a crash. Fewer chances of technical issues mean more riding enjoyment and less maintenance.
Hyperglide Cassette
The Hyperglide 12-speed cassettes are designed for both comfort and efficiency. Thanks to a smart gear distribution – with the ‘sweet spot’ around the 6th to 8th sprocket – you can keep pedalling smoothly even with larger gear ratios. They’re also compatible with standard Shimano HG 11-speed freehub bodies, making upgrades hassle-free.
Smart and Simple Brake Maintenance
Shimano has greatly improved brake maintenance. Bleeding can now be done without removing the caliper, thanks to a newly designed bleed port and rotating valve. An optimised funnel and spacer make the whole process faster and cleaner – perfect for both the home mechanic and the professional.
