There are 40t and 42t chain ring options. It represents a ground up look at how cyclists want to explore their world. Stages Gen 3 single-sided Power L meter built onto a non-drive-side Shimano GRX RX-810 crank arm. SHIMANO GRX, with its gravel specific ergonomics, optimized gearing options, rugged reliability, and quiet and stable drivetrain, sets itself apart from the rest of the component world.
Of course, such wide-range gearing is also well-suited for 1x gravel riders.Shimano’s new GRX gravel/cyclocross family of components has one wheelset, the 21.6mm wide RX570 wheelset. It comes in both 700c and 650b diameters.Yet with its wide-range 2x gearing, 1x options, inline brake levers, grippy levers, value-packed wheelset and even 10-speed compatibility, Shimano’s GRX family of mechanical components really has something for everyone.Shimano pulled out all the stops with its gravel-oriented GRX family of components.Think 1:1 is as low as you need?

Price: $349.99. Length. © A. Yee / Cyclocross MagazineUp front, Shimano has some work to catch up to SRAM’s offerings, with just the 40 and 42t wide-narrow chain ring options, compared to SRAM’s 6 different 11-speed 1x chain ring offerings, starting at a 36t and ending with a 46t (SRAM’s 12-speed crank comes with a whopping 8 chain ring options from 36-50t).Shimano’s gravel-oriented GRX mechanical components offer wide range 2x gearing with a 48/31 chain ring combination.
The 2x11-speed crank is available in a 48-31T chainring combination and 170, 172.5, and 175mm crank arm lengths.
It shifted well but was more challenged with chain wrap duties. On paper, the 110mm four-arm BCD looks exactly the same as what its four-arm road cranksets use and third-parties have copied, but Shimano assured us that mix-and-match fans hoping to put a 46 or 50 tooth Ultegra ring on a GRX crank will be disappointed. © A. Yee / Cyclocross MagazineShimano’s gravel-oriented GRX mechanical components come in both 1x and 2x drivetrain options.
That’s a big bummer.Both the 2x-oriented RX810 and 1x-oriented RX812 rear derailleurs offer the crisp shifting you’d expect from Shimano, without chain slap. Used within a Shimano 1x11 speed drivetrain, it will help you maintain your momentum on familiar routes, while its optimised design excels on gravel and muddy surfaces. You'll benefit from its lightweight alloy construction with Hollowtech II crank arm technology, which delivers a superb balance of stiffness, strength and rotating performance.
I want more 1x chainring options, more cassette options, wider rims and more mounting positions for the inline levers, but I’m sure most of those are already on the drawing board.
Europe, however, gets a 10-speed 1x crankset as well.Inline brake levers are back thanks to Shimano’s RX812 sub brake levers, and they’re a fun addition to the handlebar.
Please note this offer is only available to physical shipping addresses in California(no PO Boxes), and oversize charges still apply on some heavy/large itemsSome manufacturers restrict where we can ship their products. Used within a Shimano 1x11 speed drivetrain, it will help you maintain your momentum on familiar routes, while its optimised design excels on gravel and muddy surfaces. That project will set you back about $300 if you’re running Di2, or $110 if you’re running mechanical, for the derailleur alone.
But longer gravel rides, age and ballooning tire sizes all contribute to making what once felt like a cheater granny gear into an essential for any mixed terrain adventure in hilly California. The shifting was crisper across the two chain rings as the upper pulley of the RX800 derailleur remained consistently closer to each cog across the cassette. This design should allow bike companies and frame builders in the future to maximize tire clearance without lengthening chainstays, and bigger chainrings on bikes where clearance by the chainstays is already tight. SHIMANO's new FC-RX810-1 crank balances weight and efficiency for mixed-terrain riding.
They’re not compatible and won’t work without a file or Dremel.
