With the wolfs tooth 10 or 11? I have the 2021 Checkpoint SL5

Can you tell me specifically what cassette (XT CS-M8000 11 speed??) and is it the 10 or 11 speed wolf tooth?

@@GasmanA Make sure you understand I'm using the GRX810 which has a total capacity larger than any other version "Total capacity: 40T"

Yes i have the 810 Shadow R+….should be the same rd….so you know which Goatlink? The road DM or Goatlink 11 speed? Also, thats 47T total right?

@@GasmanA The RoadLink DM (Direct Mount) is the RoadLink that fits Shimano’s GRX 810 (RX810), R7000 105, R8000 and RX800 Ultegra and R9100 Dura-Ace rear derailleurs. Since its introduction, the award-winning Wolf Tooth RoadLink has given riders the ability to easily increase the range of their Shimano road drivetrains while maintaining near-factory levels of chain wrap and shifting performance. Like the mountain-focused GoatLink, the RoadLink DM replaces Shimano’s stock direct mount link allowing you to relocate the derailleur to provide clearance for larger-than-stock range cassettes while maintaining chain wrap and improving shifting. The result-larger gear ranges that riders want and expect for their road, commuter, gravel, and touring bicycles. Compatibility Fits Shimano R9100-generation Dura-Ace, R8000-generation Ultegra, RX800 and RX805 Ultegra, and R7000 105 rear derailleurs Optimized for use with GRX ultra wide range drivetrains when using the GRX 810 (RX810) rear derailleur Fits standard derailleur hangers only Direct mount derailleur hangers are not supported. These are not common and the stock b-link that the RoadLink DM replaces will not be present on bikes with a direct mount derailleur hanger Optimized for use with 11-36t, 11-40t, and 11-42t 11-speed cassettes Will improve performance with 10-42t 11-speed cassettes, but not to factory levels Does not change the derailleurs total chain wrap capacity. www.wolftoothcomponents.com/products/roadlink-dm

Gear inches are the cycling equivalent of "on my machine," change my mind.

Goat link or no goat link?

How'd it go? Just bought one of the last 54 cm Rove LTD framesets available on the east coast and am looking to do a similar build to what you described.

I'm in EXACTLY the same boat. New Di2 gravel bike for my wife (still waiting for delivery), but the Shimano GRX gearing doesn't match her current bikes. I have been searching for solutions wanting to correct this before her first ride (although I'll probably get her up and running w/ stock set up to avoid any delays). In the old days, I'd just put a MTB cassette and RD on her 9 or 10 speed bikes. Easy peasy and cheap. I was about to try the RX817 or figure out compatibility with MTB RDs which would have been expensive (but worth it for the gears!) But this solution will be what I try first. I plan to size the chain to give a safe big-big combo and either count on the Di2 to avoid small-small (assuming the chain's too long) or just live with that. I think people are much more likely to use the big-big combo than the small-small. Plus erring on the side of too-long chain just is noisy in small-small, not potentially catastrophic like a too-short chain in big-big. Long way of saying, I'm glad it works for exactly what I'm looking for. FWIW, my new gravel bike will be Etap AXS which (a) gives quite a bit lower gearing as a standard configuration and (b) is dead simple to combine with MTB stuff if needed. No complicated compatibility stuff needed, it's just cross-compatible.

How is the set up going?

Is is able to go on the front big and small big without braking?

How is the set up running

@@artcaballerojr Yeah absolutely manages both without any problem at all.

Has been running flawlessly on my bike for a number of years now.

You needed the roadlink dm? how many links in the chain?

@@BernatCasero KMC X11EL 11 Speed Extra Light Chain 118 links and using the 10 speed wolf tooth as used in the video. No additional links were added or removed

What brand is that 24/38 crank? Thanx

Did you use a different Chain So a MTB Chain?

@@Batou_73 Hi Rory, I am using the "normal" chain which Shimano recommends for GRX: CN-HG701-11. I even didn't change the length after I changed my setup. Still works perfect 🙃

@@31180HTB482 perfect fitted my 11-40 two weeks ago. Just wonderful!!!! Just plain perfect for hilly gravel rides you still have the speed but also serious climbing capabilities!

H can I please ask a question. Is this gear ratio combination possible 48/31 GRX crankset 11-42t XT casette GRX 810 RD with Wolftooth DM 12 speed Shimano chain Thank you.

@@lexipau Hi Bücky, this should work with the Wolftooth Goatlink 10V. But when I tested, I found my combination of RX812 derailleur with RX810 derailleur arm fitting even better. But as you guess, it is of course much more expensive 😉😑

What reference is your 11-40 XT cassette? Thanks

@@pablola1001 Shimano Deore XT CS-M8000

@@rsrnsrwds thanks

I think it is for.11 speed and I need 10 speed. 11-40

@@pablola1001 Look at this these, Shimano Deore CS-M4100 10-Speed Cassette in 11-42t, or the Shimano Deore M6000 CS-HG500-10 which now has an 11-42t option.

The new magic script is the shimano road or GRX FD can work with 18 tooth diff chainring. Such as 48-30, 46-28, 44-26 and 42-24. so 2 smaller cogs would be better than 2 big ring right now.

​@@user-zu4nl7bm9esounds great, although I can't find anything on that setup. Can you tell me more or link something?

Why don't you just use the grx derailleur that's meant for 11-42 cassettes? They do exist! (GRX RD-RX812 and RX817 for di2)

@@sebastianjost Yes, but they're not meant for 2x.

@@sebastianjost $$$ compared to this solution. Plus, if I'm not mistaken, their chain wrap is no bigger.

@sebastianjost The upper pulley is offset from the pivot point of the cage. This means the pulley moves down as the der moves to a bigger ring because more chain is taken up. The problem is that this will also happen when you shift from the small to big ring in the front

Except that it was a Salsa Cutthroat...

@@mikesobo9818 I don't remember if I watched the entire video, but it that is the case, then surely the 2020 model, whose rear end resembles WarBird's quite a bit.

May I ask if you are using Di2 or mechanical? I'm in the process of speccing my new bike, and I'm thinking 48/31 front and 11/40 back, but not sure the chain will be long enough... or that Di2 can be set up like that!

@@dlevi67 I'm running mechanical but by all accounts Di2 is even better as you don't have any issues changing under load whatsoever! I normally have to remove about 3 or 4 link's on KMC chains. I would start with the full chain then just remove a link at a time till you are happy👍

@@adski71 Thank you very much!

I’ll do that next. I’ll need to get a bigger chain and that cassette, it can be done.

The RX400 RD won't work with a 11-42 cassette?

Running exactly the same set up which was working perfectly, although cross chaining has become an issue lately.

oh damn that's a wide ratio. how did it hold up?

Thanks for sharing this. I am running the grx400 46-30 x 11-36 and am looking for a bit more climbing gear. Good to know that the goat link works with the larger cassette. Did you end up trying 42? Curious if that would be too much. Thanks

@@timothydoyle8269 After much trial and some error I finally ended up with a slightly different tweak. Things worked just great but I wanted them to work even "greater", if you catch my drift. Kept the 11-40 cassette in the rear, but I got a GRX RX812 rear derailleur (yeah the one for the 1x11 drivetrain) and also a Garbaruk derailleur cage. In that cage I then put the original jockey wheels from the RX810 derailleur as to get enough "leverage" to really keep the chain taught enough on the high end of the gears. This set up did away with the fact that I, after some use, noticed that the Wolftooth slipped for me, and had me need check it a bit to often for my liking. I think that a Wolftooth with slightly longer reach, and "set angles" - sat 5 degrees apart - would be the cheap ticket. Sadly, that does not exists. I say; get a Woolftoth and try it! I had immensely fun until it just started to get a little bit annoying. But it was so worth it so I do not regret a minute of that tweaking. Now, with the last set up, things pretty much feels like factory stuff, with the only exception that if I cross shift big/big, the gears protest.

​@Hermod_Hermit have u tried any new set ups or still with the 812 in back

@@artcaballerojr Nope, gone with a Garbaruk long cage on the same 812 derailleur, and that really smoothed things out to another level entirely. No more Wolftooth, despite it working just fine. Looks cleaner. I also used the old jockey wheels from the 810 derailleur to get the chain length just right. But as of late I've fallen in love with then new 1x12 GRX system, so this bike has seen little use this season.

Hi. Do you have RX-810 or RX 812 rear derailleur? How many links does your bicycle chain have?

hi jon are you running a 2x system and any reason you went for a 11-40t over a 11-42? does is shift better on a 11-40

@@wingit8288 I think it could do it but sounded like it would be pushing it just a bit. 11-40 felt a bit safer than 11-42, and I wouldn't worry about breaking things if I accidentally shifted big-big for some reason. Also, it sounded like I might need to add some chain links to get things working OK with 30t/42t. There's another video that talks a bit about this: kzfaq.info/get/bejne/rbSVjLx-nsXFlYE.html

Neil Henderson With a standard “B” screw, or did you swap out the standard “B” screw for a longer one?

Neil used the XT CS-M8000 cassette.

Nice. That's the sort of setup I'm after. Can you share some details about your front derailleur? Is it GRX, and did you need a braze on adapter to reach all the way down to the 26t chainring?

@@dennismicallef9350 it's grx and it reaches super close to the chain stay. My frame hasn't anything welded on for front derailleur, so I could freely move it around.

I have just tested 11-42 on 105 5800 GS (there ist no SGS!) using a RoadLink-Copy. The manufacturer Bikeco/Bolany sells cassettes with that copy as a gimmick in good quality (both of them). 11-42 ist not as easy to handle as with version 7000 (which is similar to GRX 810). I guess on version 5800 11-40 would be fixed much easier. The RoadLink copy would also work on version 7000 or GRX 810. Different to RoadLink DM, it has to be installed addittionally, not replacing the original Link.

The 817 and 812 (I think are their names) are meant for 1x drivetrains and can therefore be used with larger cassettes. However the total capacity they can absorb in chain length is smaller than that of the 2x rear derailleurs. So when trying this conversion, you're better off with the 2x derailleurs (810/815). However someone else mentioned that using the derailleur body of the 1x derailleur and the cage of the 2x works very well for 2x drivetrains with a large cassette (like 11-42)

Hey Rex, I'm of the mindset that you should trust your bike shop and I would assume they checked that b-screw. I know some setups work better than others and some drivers shift better than others. I say give it an honest try for a few more weeks before you make a decisions going forward. That being said, the GRX 815 has been an incredible drivetrain so far, exceeding my expectations and being pretty friendly when working with cassettes that are technically not compatible.

@@BIKEPACKINGcom Loved the video. Lots of golden nuggets of info. I've been looking to maximise capacity on an upcoming 1x Di2 build. The e13 TRS 9-46 paired with a 38t up front seems to tick all the boxes. I'm still in two minds as to what RD is required. Do I go full mullet and get an XT or XTR, or does the GRX 817 suffice? Any goat links or longer cages required do you think? The recent Guide to Mullet Drivetrains article was great but left me with some questions!

Ur running rim brakes correct?

@@artcaballerojr I was running mechanical disc, I’ve now upgraded to rival 22 hydro and an 11sp 11-36 cassette.
