Pro tip, Russ - if you’re chewing up Phillips screws it’s often not just that the screws are made of cheese, it’s that they are actually JIS (Japan Industry Standard) screws. They look like Phillips but they’re not. Get yourself a set of ‘Vessel’ brand JIS screwdrivers and voila, no more chewed screws! What’s more, the JIS drivers work perfectly well on standard Phillips fasteners. Once you’ve experienced the miracle you’ll wonder why you didn’t do it earlier! (PS, feel free to slap me if you’re already all over JIS) hope Laura is doing well!

Pretty sure this is not a JIS, because s-ride is from China. Newer Shimano products don't use JIS screws either. They all use screws which can be fastened with ISO 8764 screwdrivers. If it is a JIS screw, the screw should have a mark (point or a little x, source Wikipedia: List of screw drivers) on its head. However, worn tools on the other site are one of the most common causes of stripped screws.

Here's a pro tip, just use a flat head. Simple is as simple does. Cheap Chinese stuff often uses compromised parts and materials so it's not very surprising. We ALWAYS PAY for what we get, one way or another. You could easily get high grade socket head screws for a buck or two and problem solved. Ive never been able to figure out why there's so many different screw heads. Job security for somebody I suppose.

I surely needed this video 2 years ago and will likely need it again in the near future. 2 years ago everyone told me what you just demonstrated was not possible. Desperately searched for an alternative to allow my 190 lb-63 year old body to pull long hills (strangely, I love the grind). Ultimately, I rigged my Salsa TI Fargo with a SRAM GX Eagle MTB drive train (30T front & 10-50T rear) for bikepacking adventures. You just proved a 46-30T front and 10-42T rear with brifters will provide me the low-end range needed to haul my carcass over major ranges in the future. I love you man!

I have a nickname for you: king of low gear! Btw, i run 9 speed shimano sora on my gravelbike with 46/30 crank and 11-40 sunrace cassette with a alivio mtb rear derailleur (with no link to extend). Runs flawless for 2 years now👌

This single up front with a dinner plate in the rear is just trendy nonsense. If you can't adjust a front derailleur, maybe you should be in some other sport.... Learn how to use your gears so you don't cross chain, and shifing becomes a joy. Having the ability to shift up front is like quickly shifing up or down 2-3 gears in the cassette. Quick and simple snappy shifts. Hopefully these parts will be available for a long time.....

Same here. I totally get 1x for MTB, not sold on it for gravel, bike packing or road. I was building a mega 2x drive train which I was testing on a project bike before I track down a frame for final build. Unfortunately, I had an issue with the Sunrace M9 derailleur (unrelated to the setup) so didn't get to test the 1x with 2x setup. Currently microshift long cage with moderate 11-28 on a 3x front. Good enough for unloaded class 1/2 gravel and the road stretches. Getting all the gear range out of 2x would be optimal vs 3x But future plan is something like 2x9 with 11-36 or 40 and 50/32 up front.

I'm an old road racer turned trail rider. Cadence is important to me. I can't stand the huge gaps between gears on 1X. I like small gaps between each gear to get my cadence just right for really long rides. If I want to always be in the wrong gear I ride one of my singlespeeds! I ride roads to get to trails and link up more trails with roads in between the trails. I need a big chainring for road riding and fast descents and rolly trails. A middle gear for hammering out steeper climbs and a little gear for the last few steep climbs after 40 miles of tough trails or when hauling my 'household'. Even 2x barely gives enough range to pedal on trails. 1x is ok for really rough trail riding, short rides and gravity runs. It doesn't work for me when endurance riding. Multiple chainrings and front derailleurs are simple to use IF you know how to wrench, know how to shift and know how to choose gears that tension the chain on the rough stuff. It worked fine for decades for me. I'm too old to compromise! I'm moving to Colorado and retiring. 3x will be on my bikes for a long time.

Thanks Russ. I love the Cave of bad ideas! Not a combination I am interested in, but I love seeing what is possible.

B screw problem fix, just relieve some pressure off of the contact point by swinging out the derailleur backwards, then proceed with screwing in the B screw. But then again having a correct tool is also a good thing!

Your combination of 46-30 chain ring with 11-50 cone works out (in gear inches) to a range of approximately 16-112. I have a Brompton six-speed with a 54T chain ring, and a Schlumpf Mountain Drive. My range is approximately 14-108. Just what I need for climbing hills in the Pacific NW area.

I’ve wondered if such a combination would ever work. Thank you for experimenting to show that it can with some limitations. Though I would not have a problem with a set up where the big ring would not work with the biggest cog in the back. It’s hard on a chain and derailleur to do that anyway. I try to avoid it with my less radical set up now.

Im planning on running 40-24t CS with 11-34t rear cassette. What derailer are you running?

Interesting video - I recently had a conversation with my local bike mechanic asking if I could change my GRX 11 - 42 1x into a 2x. My argument was, like you said, the chain should never go to extremes front to rear and really should only go a couple of places past half way for each chain ring. His answer - Shimano Sram etc don't let them do it because they cannot rely on people knowing how to use their gears properly and they won't guarantee the work if you do. So it came as no surprise to see it worked on your set up. Another point about the GRX system - I was recently cleaning both my bikes thoroughly and noticed that the free hub on both are identical. One is a 12 month old GRX 1 x 11 (Ribble CGR) the other is a Surly Ogre with an 11 year old (But still working fine!) 3 x 9 XT set up. I know the 11 speed XT will fit on the old hub I just wonder if the GRX will operate an 11 speed XT?

Reminds me of my old dingle speed set up. Double single speed. One speed for thrashing about town, another for carrying a loaded trailer/ going up and down hills. Had to take the wheel off to manually change gear, which was a bit of a ball-ache! 😂

I like it. I have a Jones that I ride on the road quite a bit. Often thought having another chain ring up front would help give some extra steps. Not really big, maybe 6 teeth more than the small ring.

This was a fun video! Thank you

Ive never used Patreon but cheers for giving me a shout out! haha

Great vídeo. I like the bad (good) ideas 😊

Russ, nifty work! You can pull the derailleur back by hand and then turn the B screw instead of making the screw do the work. For the limit screws, you can shift to the adjacent gear and go a quarter turn at a time and then shift back to test it. It might save your screws heads.

Campagnolo Chorus 10 speed on the rear and down tube shifter on the left for the triple with my TA crankset and Huret Jubilee which I will shift just a few times here and there. I use it 90% as a 1x10 which is a great range of gears for normal riding (38 x 11-29) and I still have the 28 for hills and 46 when I catch a ride behind a faster group of riders once in a while.

Good video!! I am running 40/27 with 11-40 cassette and an xt 10sp derailleur with 105 shifters, the idea is to go 44/28 in the front as soon as I wear out the chainrings that came with the crank... is it a double mullett? :)

For anyone doing a 2x or 3x with a rear derailleur that is past it's max capacity it is best to set it up larger ring (opposite of the video). The reason is that you will still have access to to lowest gear but have less rink of over stressing the derailleur by inadvertently shifting beyond it's capacity. I have done this on a commuter/ touring bike [46/38/24 x 11/30] 945 tooth difference) on a Shimano 105 GS (39 tooth capacity). The derailleur held tension on the 24 x 21/30 (last 4 gears on a 9 speed). only used the 24 as a bail out gear on tough hills never had a problem with chain slack and by the time I was gong down hills or on the flats I'd shift up to the 38T front anyway. Did the same for a [38/22x 11/36]. I ride that bike like a 1x + bail out. The 22t in in tension from the 15-39 (7 gears on 10 speed) on my bike.

I'm running a SRAM Apex 50/34 in the front and GX 11/36 in the back, and I do like the range. I use a stock KMC X10.93 116 links. This is cool. If I could ditch the front derailleur and have around that kind of range I'd be ecstatic.

More bad ideas! LOL double mullet madness, Thanks for this info. My daughter but home a letter from school stating ; " haircuts such as mullets are banned as they are considered extreme haircuts"! "Students will be sent home to have the hair rectified"! Private school mullet madness.

Lawd, I was on the edge of my seat as you approached that big big combination. lol TENSE

Great vid... I'm looking at reducing 2-3 bikes to one with a fast aluminum 2x gravel bike that can take a rear rack and do a bit of lightweight touring. Totally new to the gravel world and way out of date on MTB stuff, I've been in road and single speed land for the last 10+ years. Anyways, all the 2x GRX gravel bikes have 30-34 or 31-34 granny gears which on 700c leave you in the 25 gear-inch range - ok for riding, a bit high for touring. What I don't (yet) understand, is if there are GRX derailleurs made for up to 42t cassettes, why are there no bikes with drop bars + GRX 2x setups that feature the 812 rear mech and an 11-42t cassette? Aside from the cost (maybe $200-240 for a new cassette, mech, and chain) this looks like a bolt on thing that should work well and be in spec - or am I missing something?

Awesome! Always interested in 2x 11-46 or lower set ups. I was able to make a SRAM 2x10 11-46 work for quite a while on my Trek 920 using a very customized hanger extension that eventually broke (fortunately while on the work stand) and I have been looking for a more reliable way to get another 11-46 2x10 setup pieced together.

I'm also looking for a way to upgrade my stock 2x10 11-32 setup. First time trying to move out of my stock Shimano GRX components, it seems like 11-40 is a safe frontier been done with good success by other folks. Hoping to make the plunge soon!

Nice one! Just in case I had a bad idea like that, I only have to watch a video to know for sure that it's, somehow, a "not so bad" one ;)

Thank you so much for this video. Planning something very similar with 11-46 and 48/31, except using larger jockey wheels and possibly a goat link to allow a longer chain to get all gears. Your video has just convinced me it's workable! I'm pretty sure with the additio. Of jockey wheels, a goat link and a longer chain you could potentially get all gears with 11-50. So many naysayers postulated my bike will explode and the fires of hell will open up to claim the abomination that will result from such a indulgently geared drive train.

Quick tip on the b-screw...un-tension the derailleur from the hanger stop for the b-screw when you tighten it in and you shouldn’t have an issue with stripping the head, unless the threads for it are f’d. Also tip: to get even more massive range from b-tension you can screw in the b-screw from the other side of its hole, meaning from the underside of the derailleur...may require a slight bend in the screw itself to align properly with the derailleur’s b-stop but you will be able to run an even larger rear if desired. My 2¢

All the screws are soft. Even the high and low set screws. They used cheap screws.

Does anyone know if the RD GRX400 works with a 10-speed 11-42 cassette and a 46-30 front? Thanks

Good Stuff - thank you!

Thanks for this.

Love the concept here, I'm always trying to push the limit of what a 2x set up can do. Listed Chain Wrap Capacity for the derailleur is 49T and here you're trying to get it to throw a whopping capacity of 55T! Still, this derailleur has most others' capacity bested by at least 2 teeth. Very sick. Drop that cassette down to a 11-42T and bob's your uncle.

The Microsoft advent comes in a long cage that can shift up to 46t and advertised on their site as 2x/3x. There's no road sniffed for the left, but a bad end could give you a massive range 2x9. Really thinking about trying it on a Poseidon Redwood. Probably have to go smaller than 46/30.

DO IT! I have the Advent 9 speed long cage deraileur with a 11-40 sunrace cassette, and 42/26t touring double cranks (rebadged Sugino XD2 available from Soma or Rivendell) and a Microshift Marvo (3x9S) FD-M43 front deraileur pulled with a Sunrace thumbie. 2x9 with a thumbie for the front deraileur is the best! It gets down to about 17 gear inches in 40t rear x 26t. Which is quite ridable if you are fully loaded.
