SHIMANO FC-RX600 GRX chainset 46/30, double, 11-speed, 2 piece design

Product Information

Two-ring SRAM options in the GX-1000 model include a 36/22t 11-speed crankset, with the additional option of 38/24t chainrings in 10-speed. The budget S-200 offers a 42/32/22t triple chainset with 9-speed gearing. If you have a 130mm BCD crankset, for example, the smallest compatible chainring is a 38t. On a 110mm BCD crankset, the lower limit drops to 33t, and so on. For the moment the big three — Shimano, Campagnolo and SRAM — claim to have no plans for super compact chainsets. First, different cranksets may have a different number of arms or direct-mount interfaces (connecting the cranks to the chainrings), and they may be positioned differently.

But we think they have a place for general riding too. As soon as you hit seriously hilly terrain, there's going to come a moment when you need the lowest gear you can get. You might have blown up, you might have hit a 20% grade or steeper. Options like FSA's Adventure series cranks, Sugino's OS cranks, or the Praxis Works 48/32 cranks give you a slightly lower gear range for those situations. You can’t easily swap the number of chainrings your bike is set up for, because the front derailleur and associated shifter will be specific for your setup and would need to be replaced, too. I think 48/32 is probably the new scenario for Gran Fondo/endurance riders,” Bellin concludes. Our take Fitting is extremely easy, with only an 8mm hex key required, though a torque wrench is a very good idea (the rating of 45-47Nm is handily etched onto the left arm) to accurately eliminate play. Removal is just as simple, as the self-extracting bolt pulls the crank off the splines as you undo it. It takes a fair bit of force in both directions, so invest in a long key.The goal is not to dominate the Gravel scene or change its direction. Shimano did not want to reinvent the wheel. The engineers at Shimano love Graveln as he is. Shimano simply wanted to give you and your friends the opportunity to ride the bike the way you want with a new group of components. And the GRX does just that.

The triple chainring, which was largely killed off when the compact arrived, still has an advantage over a standard compact with its granny ring, but Bellin suggests that with the advent of the super compact chainset the triple is definitely dead this time.

The 53/39 chainset is now a rarity outside the professional peloton. The last bike we tested that came equipped with one was in 2017, so we should probably stop calling it a standard crankset, because it isn't. There's apparently a further need for speed among the pros though, because Shimano offers a 54/40 option on the latest Dura-Ace Di2 groupset. That's because, of course, pro cycling is much cleaner these days and without performance-enhancing drugs everyone has slowed down. Yup. Ah-huh. combination is minimally faster than 52x12T. This is 49.7km/h (30.9mph) and is faster than 53x13T! At 100rpm it increases to 55km/h (34.3mph).

For those who may find this worth considering but feel that a 46-tooth front chainring is unacceptably low, they might consider the Shimano GRX FC-RX810 crankset, with a 48/31 gear combination. This combination will provide a higher top end than a 46, while the 31-tooth chainring will offer a climbing gear that is just slightly higher than a 30. Or maybe consider the various offerings by Shimano, Praxis, FSA, Rotor, etc., of a 48/32 combination. As you can see, there are a lot of options that allow riders to tailor their gearing to specific desires. Subcompact Front Derailleur Caveats It’s indisputable that a lower gear benefits pretty much anybody who isn’t a pro, but does a super compact offer a high enough gear?

Due to very special 2.5mm offset construction of BOTH chainrings towards the frame and custom bolts: Many of Shimano’s road cranksets have four arms, but they’re not distributed evenly around the spindle. In some setups, the BCD arrangement is even more complicated. The inner chainring is sometimes fitted to the inside of the outer ring, or separately onto the crank spider. or 48/11 is still a big gear to push on the flat. For your daily ride you most likely don't need more
