For your riding freedom: the Gravel GRX Di2 2x12-speed STI Dual Control ST-RX825 + BR-RX820 Disc Brake Set from Shimano
Gravel cycling is not meant to be overly complicated. The heart and soul of cycling’s drop bar, dirt road discipline is rooted in simplicity, inclusivity, and adventure. No ride is out of bounds. All are welcome to join. Gear should be functional and reliable but need not break the bank. That’s why whether you’re a grizzled gravel cycling veteran or brand new to the road (or trail) less traveled, you’ll appreciate the latest iteration of Shimano’s groundbreaking—and industry-first-gravel-specific GRX component group. Designed to help you get the most from your next unpaved adventure, RX825 delivers top-tier performance without an over-the-top price.
For riders seeking the best of both worlds, the new 2x12 RX825 UNDROPPABLE drivetrain is the choice. Utilizing a gravel-optimized 48/31 or 46/30 front chainring paired with an 11-34 or 11-36 cassette, this setup delivers an ultra-wide gear range so you can spin a comfortable cadence whether cruising the flats, smashing endless dirt road rollers, or tackling a massive backcountry climb.
Alongside this suite of gravel-optimized gearing options is the new ST-RX825 brake/shift levers. Specifically designed for use with flared handlebars that are a gravel-cycling staple, the new lever body design features anti-slip texturing on the tops and dramatically improved ergonomics that lessen pressure on your palms. Together, these changes increase comfort and control so you can fearlessly tackle tricky terrain or focus on the rolling gravel road ahead.

SEIS SHIMANO ELECTRONIC INTELLIGENT SYSTEMThe SEIS innovative shift technology is still based on the SHIMANO INDEX SYSTEM (SIS) that has proved its superior gear changing characteristics over the years. The big difference is that in this case, the shifting action is provided for by electronics instead of mechanics. This electronic shifting system has been extensively tested over past two years by several professional riders in all conditions possible, such as rain, mud, low temperatures, cobble stone roads and combinations of all of these at the same time. Shifting is executed by simply pressing the button. No power is needed to shift, which gives important advantages since it is easier now to always keep a tight grip on the handlebar and to keep your concentration on riding instead on shifting. The shift system allows accurate and effortless shifting in difficult circumstances like when you have cold hands or when you are completely exhausted. Furthermore, the shifting performance will never be affected by contaminated or stretched cables since the shifting signal is transferred electronically. The operating buttons work similarly to mechanical Dual Control Levers so you don’t need to re-program your mind for a new system.
