Grx-812 shadow plus 11s / 11-42

-

At the beginning of the year I upgraded my gravel's brakes and drivetrain to Shimano GRX, it came from SRAM Apex single chainring. They installed a GRX-810 derailleur at the store, but lately I was having trouble engaging 11-42. By switching to GRX-812, this problem has disappeared. Very happy with the update.

GRX - Another Quality Product from Shimano

-

Have Shimano on all my bikes. Decided to go with the new GRX on my gravel bike. Not a lot different than an XT derailleur. I am running the 2x10 GRX crankset with the GRX 2x11 front and rear derailleur and everything is working fine. I am also running a 42t rear XT cassette with no issues. Not sure I could run a bigger cassette unless I got a longer b screw. As it is now I have about 5 or 6 mm between the 43t cog and the derailleur jockey.

Shimano has hit the spot again. Perfect in operation. And compatible with road handles. With an enviable finish and details like putting the fine adjustment screws with Allen head and of the same size.

Nice product from shimano. Delivered the products as expected!

GRX - RD for the double crankset

-

got this as part of my grx drive train upgrade on my gravel bike. i have the grx double crankset and the 32t option is the one you would need. it's the rd810. with the clutch! i did consider getting the rd800 but on shimano's site it lists the 800 compatible with the single ring set up. in case i went down that route. but it's shift geometry would be different as it supports a 42t low gear. i stuck with what shimano lists on their site for my 2x 11sp set up on my gravel bike. i was used to the 2x 105 setup that i currently have and prefer the ability to find a gear i can spin in. i have tried 1x and like the the simplicity. i have that on my mtb. but for road/off-road less technical terrain a 2x gives me more flexibility. also chain line is less severe with the 2x. a 30-32 gear will be better than a 42-42 on the single having ,a 46-11 high gear will be good for my riding capability. it came in all original shimano grx packaging.
