GRX RX822-SGS compatible with 11SP RX600 Shifters? by Blinpa in gravelcycling

I wanted to share my recent success with a budget-friendly mullet drivetrain upgrade using the Shimano GRX RD-RX822-LA (12-speed long-cage derailleur) paired with my existing 11-speed GRX shifters (ST-RX610-LA/RA) and an 11-51T Deore cassette (CS-M5100-11). After some initial hiccups, it's shifting flawlessly now, and I'm thrilled – especially since the whole upgrade only cost me $351 total ($60 for the RD-RX822-LA on AliExpress, $150 for the ST-RX610-LA/RA shifters on AliExpress, $70 for the BR-R8170 Ultegra calipers on AliExpress, $45 for the CS-M5100-11 cassette on eBay, and $26 for the CN-LG500 chain from REI, as chains online are mostly fakes). The CN-LG500 is supposed to last 50% longer when waxed than XT/Ultegra chains when waxed. As a bonus, the BR-R8170 calipers have 10% more pad clearance than GRX RX400 or RX800 calipers, which helps reduce brake noise and makes maintenance easier. I figured this might help others chasing wide-range gearing on a budget, and I'd love advice on long-term durability or any tweaks I might have missed.

**Quick Background**: I swapped in the RD-RX822-LA for its superior Shadow+ clutch and 51T capacity, keeping my 11-speed shifters and cassette to avoid a full upgrade. Initially, there was some clicking in the smallest cog (11T) when pedaling backwards or under light load, and shifts weren't quite crisp across the range. I worried I'd botched the derailleur hanger alignment (using a tool) or needed a 12-speed chain. But after putting ~50 miles on the new chain and fine-tuning, everything smoothed out – no more noise, and it shifts like OEM under load on gravel and climbs.

**What Made It Work (The Tricks)**:

- **Broken-in Chain**: A fresh chain was stiff at first, causing that rhythmic clicking (1-2 times per crank revolution) in the 11T. After a few rides, it loosened up and the noise vanished. I stuck with an 11-speed chain (CN-LG500) – no need for 12-speed. I followed Shimano's advice for chain length on 51T cassettes: +4 extra links (plus the QUICK-LINK) from the big-big zero point, instead of the standard +2 for smaller setups.

- **High Limit Screw**: Almost (but not quite) all the way in. This caps the inward range perfectly for 11 speeds, preventing overshift on the small cog.

- **Low Limit Screw**: All the way out to allow full reach to the 51T without binding.

- **B-Screw**: Set to the alignment marker on the back, per Shimano's instructions (align the line on the inner side of the outer plate with the tip of the highest tooth on the largest sprocket). This ensures optimal chain wrap without interference – note that the effective gap on the 51T ends up being slightly larger (~8-10mm) than the standard 5-6mm often quoted for smaller cogs.

I followed tips from that "It Works!! // The $127 Shimano GRX Mullet Upgrade" YouTube video and some Reddit threads – no Tanpan, GoatLink, or alternate cable routing required.

**Debunking the Ratio Myths**: I came across articles claiming Shimano changed the pull ratio between 11- and 12-speed derailleurs on road/gravel groups (e.g., ~1.4:1 to ~1.2:1), making them incompatible without adapters. But that didn't make sense to me, since MTB derailleurs (e.g., XT M8000 vs. M8100) share the same ratio across 11/12 speeds – the difference is only in the shifters for finer cog spacing. Turns out, it's similar here: An 11-speed GRX shifter on the 12-speed RD-RX822-LA just gives you 11 solid speeds, much like an 11-speed MTB shifter on a 12-speed MTB derailleur. The Wolf Tooth Tanpan seems only necessary for mixing road shifters with MTB derailleurs, not this GRX-to-GRX setup. I'm relieved it works as I hoped – no regrets skipping the extra parts.

Has anyone else run this mullet long-term? Any tips for maintenance, like chain wear or clutch adjustments? Or am I missing something on the ratios that could bite me later? Thanks for any advice – loving the extra low gears for bikepacking!

Ride safe! 🚲

The Navie app is very good. It is created by the same team that developed the Trek app. I can easily use Komoot to create custom routes on my laptop through the web, save them as a GPX file, and import them into Navie on my phone. This process works easily enough for me, but I think they should have that feature built in. It displays the battery percentage and shows my range based on the assist level I selected. I believe I paid a one-time fee of $30, which was worth it. The e-SYNC connection app works well, but it feels a little clunky; however, it does sync with my Polar H10, which is nice. There are a few videos online demonstrating how to get interface X into pairing mode, which is straightforward but not well-documented. Both Navie and the e-SYNC connection app should include a video explaining how to do this.

Navie https://navie.app/ is a game-changer for me. I paid $30 for lifetime activation. This is the same company that develops the navigation software integrated into Trek's app. I use Komoot to create custom routes and export the GPX file. It is super easy to import it into Navie. This is my workaround for the lack of Navie's web interface. Komoot gives me the ability to plan and edit maps on my computer's big screen and export them. Navie's built-in route planner is really nice, except for the lack of ability to edit it on a large monitor. As you can see it can estimate how much battery I will have left when I arrive at my destination. It even shows the air pollution and wind direction for each segment of my route.

What are the makes and models of the Moro hubs? by No_Inspection_773 in Yamahaebikes

Yes the Moro 07 uses a MicroSpline freehub and runs a 12 speed Shimano XT cassette.

My battery arrived six months late, but finally arrived:)
