FRANA DISC HIDRAULICA SHIMANO GRX ST-RX825/BR-RX820 1ST GRUP J-KIT DIRECT Spate Noutate

It can be a real challenge to brake safely and shift gears precisely on gravel bikes due to the high speeds, different surfaces and often unpredictable routes. With the combination of the GRX Di2 ST-RX825 electric shift brake lever and the matching BR-RX820 brake calliper, Shimano brings comfort and control together so that you can master any unforeseen situation on your gravel bike.
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 2×12 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.
