I once asked Joe Bell to provide touch up paint for his standard red bike color. He said it is not possible to put the paint he sprays into a touch up bottle. He recommended using standard nail polish in the closest…
Yes, the new RX400 rear derailleur has the same parallelogram as the 11 speed units and is compatible with 11speed shifters.
John - sounds like your chain is too short or you need to adjust the limit screws.
John- SRAM makes the 10-42 cassette. SRAM and Shimano have the same spacing and are compatible. The 10-42 will need an XD driver hub though. John wrote: Here is my experience with the Shimano 11-42 cassette. Background:…
Yes, but only if you have the GRX 400 shifters. Not other 10 speed shifters, because it is really an 11 speed RD. kevinviray8892 wrote: Hi guys. Does anyone have an idea if the GRX-RX400 RD would go well with a 10spd…
Hey, I found this giveaway for an awesome gravel bike, check it out! https://swee.ps/oVwfF_TLzQiv
No RD-RX400 will not work with 10 speed shifters other than 10 sp GRX 400 and the new 10 sp Tiagra. borxes wrote: You said Ultegra 6800 11 speed shifters with RD-RX400, I ask ST-RX400-R 10 speed lever with RD-RX400 -…
Yes it should work for 2x depending on your overall capacity/ chain wrap.
Mark- I am using an 11-42 and it works great, so a 41 should be even better. Mark_S wrote: Thanks for responding Erik. Just to confirm as well - it doesn't matter that I'd be using this as 2x11? The capacity of 41T is…
Mark- Because the GRX 10 speed shifters are using the 11 speed RD tech. They won't work with typical 10 speed RDs. Just like the last version of Tiagra 10 sp.
After a few more months of almost daily use, the Shimano GRX RD-RX400 rear derailleur with an 11 sp 11-42 cassette using Ultegra 6800 11 speed shifters is working flawlessly. No RoadLink etc, all stock. I do turn the…
My long term review of the Shimano GRX RD-RX400 rear derailleur with an 11 sp 11-42 cassette using Ultegra 6800 11 speed shifters: It works great! After a few long gravel/ MTB and road rides, it is shifting great! Much…
The GRX 400 shifters (just like the latest versions of Tiagra) use 11 speed technology in the rear derailleurs, but just pull more cable to shift to ten speed (than Shimano's 11 speed shifters do). Therefore the 10…
I installed the Shimano RD-RX400 today with the ST-6800 shifters and the 11 speed 11-42t cassette (1x setup w/ 42t front chainring). It shifts through the whole cassette with b-tension screw almost all the way to its…
I went ahead and bought the Shimano GRX RD-RX400 rear derailleur. I have heard that the RD-RX810, which is rated for 34 max works well with an 11-40 cassette. I am hoping that the GRX RD-RX400 (which is rated for a 36…
Has anyone tried the Shimano GRX RD-RX400 rear derailleur with an 11-42 cassette? I am currently running a 1x11 using Ultegra 6800 shifters and rear derailleur with a WolfTooth Road Link and an 11 speed 11-42 MTB…
i am also looking for carbon and thru axle. That IRD Carbon MCX looks great, I wish they had a 20% sale now.
Wanted to Buy: carbon disc cyclocross / gravel fork with 1-1/8" straight steerer.
What I have discovered is that all 3 GRX groups (RX400, RX600, and RX810) are all based on the Shimano "road" 11 speed derailleurs (just the RX400 is 10 speed but with a pull ratio like Tiagra 4700 which is different…
Also, do all three (RX400, RX600,and RX800) just use the exact same "rebranded" flat mount road calipers like these Ultegra BR-R8070:
