GRX first report

[Kirk007]

Just replaced Sram Force 1 1x11 with GRX 600 and very happy with the change. Same reliable Shimano shifting, works perfect with Sram 10x 42 cassette. Prefer the shifter shape too. It's big, bigger than Ultegra but not the Easter Island monoliths of Sram Force 1. I think it looks better too.

are the hoods cover floppy? I had sram hydraulic and just from bleeding the hoods were all floppy... I know other people had the problem too, is this the same with GRX?

And you mention they are smaller than sram? they look shorter than sram but they look fatter, also reach seems pretty long?

Looks like you got those calipers sorted! Glad it worked for you!

Thanks for posting, I was thinking of doing the same. Really not a fan of the Force levers... the shape and the double tap shifting, aren’t my favorite.

Hey Gregg -

The GRX derailleur can handle a 10-42 cassette?

Shimano rates the long cage as good for up to a 42, I've heard some murmurs of the 10 not being the smoothest running gear with the GRX.

I think I'd go the opposite and try to run a 46 in the rear. With a 40t front on the 1x setup there just isn't enough range out back. If you ride steep gravel, and it pains me to say this as a diehard Shimano rider, you should get SRAM.

That SRAM AXS doesn’t offer anything between 10-33 and 10-50 has me looking at GRX Di2 for 10-42 or 11-42.

I don’t get why SRAM abandoned that gravel cassette that so popularized their 1x.

I am running 10-42 with my r8020 mid cage and it works fine with a 44t oval up front and it works pretty good although the 10t isn’t really used too much. Just tried out the Sram Apex 1 long cage yesterday with an 11-42 with a 42t oval ring up front and it shifted though the gears flawlessly.

Don’t know why sram decided to abandon these ratios with the axs etap other than trying to force folks into buying the sub compact cranksets and smaller gear ratios in the back. Does Sram even offer a rim brake 12spd etap group?

This is the issue I’m having right now, whether to stick with axs and try to hack a 1x ~400% ratio with other cassettes or go with a 2x axs or even a 2x grx setup. 3t made a good primer on hacking axs here:

They make force and red axs rim brake shifters. But the exclusion of a viable 12 speed 10-42 is perplexing. Maybe since they “improved” front shifting by limiting the jumps to 13 teeth they assume it’s easier and/or more lucrative on their end to have buyers for with 2x if they want the gravel gearing ratio. Or they’re admitting that the jumps in a 1x setup are just too much for gravel usage without actually admitting it.

I would try the rotor setup mentioned in the 3t article but I’ve heard that their cassettes shift like garbage.

I would not call it hacking axs, sram said from the get go that you could mix both the mountain and the road.

They do need some more variety of cassettes. 10-33 is too low and 10-50 is just too much. Where are the 40T and 46T cassettes? Maybe even a 36T cassette.

Nope, nor does it offer a mechanical 12s road group of any kind.

It's hacking in that you’re using cassettes from other manufacturers like rotor or even smaller outfits like e13, sunrace or even something like garbaruk to account for the lack of mid spread options directly from sram. Something like 11-48 or 10-42 would be great for gravel 1x and 12 speed. Or even better if Rotors shifting and ergonomics were above Microshift levels that would be a viable option.

Are you serious? While they don’t offer a 12s mechanical group I have a set of rim brake red axs shifters in my parts box. They also offer force axs in rim brake.

This is wrong, no mech but you can get rim brake force and red etap axs 12speed. Friend is putting a Red group on his Parlee
