Outstanding Product
I just installed this. I was upgrading a 10 speed SRAM Force drivetrain to accept a smaller small chain-ring and a larger 11-32 cassette. The intent was to to a friend's cyclecross bike a better gear ratio for climbing on gravel rides. When i did it i ran into trouble tuning the derailleur, even with the b-screw all the way in. I bough this because it made sense and because WolfTooth generally has a solid reputation among the MTB community. Not disappointed. I loosened the chain by dropping it off the rings and installed this in-situ. It took a minute to make sure i had it set up so it was fastened in a way that it was braced and wouldn't rotate after installation. Still, it was the easiest bike repair i have ever done. For me, at least, after installing, i did not even have to adjust the limit screws. I did need to adjust the cable tension a click or two and that was it. No kidding. I should also note here that it was a huge relief that i did not have to adjust or replace the chain. I can't promise that this will be true for all installations, however; In my case i had bought and resized a chain (according to Park Took youtube guide recommendations). I was concerned that this WolfTooth alteration would force the need for a longer chain. It did not... I'm not sure about this, but the adaptor appears to swing the derailleur slightly forward which seems to address this concern. I do think an installer should be aware that they may also need to adjust limits and cable tensions... i may have gotten lucky there. if they are not comfortable with those skills, they can expect to make a visit to their local independent bike shop, but it absolutely did the job it is supposed to do. The max room on the 10s Force drive train was quoted as 28. I think i could have easily upped the range to an 11-34 (if one was available) without an issue. So... i speculate anyone could up their range by at least 6 teeth without a problem.... assuming your cage and adjusted chain length can handle the full range. I can't speak to durability and while the machining is excellent, i don't know if this will stay properly affixed, but if i have any issues i am fairly confident i could fix it with threadlock. I just didn't want to use it until the new system has some miles on it.

Great! Easy! Almost works with a triple!
I just put one of these hangers on my vintage titanium Serotta Legend because, well, every bike collection needs at least one Frankenbike, right? Lol. The rear has an 11 x 40 cassette, and just for fun, the front is a 48-36-26 triple to make things a little more wacky! The manufacturer clearly states that the hanger will NOT allow full chain wrap-up with a triple chainring, and, unsurprisingly, it doesn’t. But with this setup, there are only two “forbidden” gear combinations: 48 front with 40 rear, and 26 front with 11 rear. This is expected for a setup like this, so it’s easy to remember to avoid these extreme combinations. I’ve been doing a lot of gravel riding with this setup, and it works like a charm!

Seems to be the answer
Initially, when coming up with the idea of converting to a single (and having to get a larger rear cassette to still give me some low end) I was thinking I'd need a long cage derailer, however I realized that chain wrap wasn't the issue, clearing the jockey wheel over the larger sprocket was. I used this to make my 105 short cage work with an 11-36, coming from a 12-30. The front double was also converted to a single. It's only been one bike ride, but setup was pretty easy - I flipped my B screw and bolted everything on. Only had to bring in the high a little bit and shifting was OK. It is not quite as sharp as it was pre-RoadLink, due to the length, but it's acceptable. I am experiencing sloppier/missed shifts on the smaller cogs, but I figure I can do some adjusting to clean that up. So far, so good! I hope that the increased length doesn't cause my bike's integrated-into-the-frame hanger to bend out of alignment more easily, or snap off. I'll update this if I'm unable to get the gears to operate as nicely as I'd like - I'm very picky about shifting and there's nothing worse than taking off from a busy intersection, or somewhere else potentially hazardous, and you have a sudden and unexpected gear change while cranking the pedals for your life. UPDATE after a little under a year of use: Shortly after writing the first part, I made some adjustments and shifting is just fine. It seems to be 50/50 whether it'll get all the way into the "10th" gear (the smallest one) since I had to do some tuning to prevent it from running the chain off the sprocket and jamming it between the smallest gear and the frame. So, yeah, you'll lose a touch of fineness that comes with the 105 group, but it's nothing terrible. Running a single chainring has overall been a huge improvement, and I'm sure if consumers weren't so mis-information "More is Better" oriented, more bikes would come this way from the get-go. EDIT again: I've now got an 11-42 in back instead. Seems to work OK even though WT claims it's not supported. FYI, the SunRace cassette COMES WITH a bootleg RoadLink! Might just save ya $20. Doesn't have fancy stuff etched into it though, but it does appear to be of pretty decent quality...

Increased rear gear maximum from 27t to 34t (2x9 setup)
This works great. I have an old road bike with a short cage Ultegra 9 speed rear derailleur. The maximum gear that will fit without this is a 27t but I wanted to go with a 34t. Put this in and now I can do it! The only downside is there is too much chain length (required for the 53t-34t combo) to make it work for my smallest combo (front 39t chainring and anything less than 17t in the rear). It will shift all the way down to 39t-11t but there is too much slack. I’m OK with this since I don’t need the ratio of those gears anyway since it’s covered by using the big front ring and other gears.

Roadlink is for 9-12 speed. I installed it on my new 12-speed bike.
I have a new Canyon Endurace CF 7 AXS eTap with SRAM Rival XG-1250, 12-speed, 10-36T. I struggle in higher grade and wish to have bigger cassette. It's shameful to walk on those grades instead of cycling, not fun. Google AI and manufacturer said I can't use this Roadlink to 12-speed SRAM XPLR XG-1251 cassette with 10-44T, but I took a chance anyway. Oh, how I'm glad I did, just using my 35T (front) chainring, I can go to 44T cog with no problem without changing my chain. They say I can only use 1 chainring (front), not true, if needed for high speed I can use my 48T chainring (front) as long as I don's use it in my 44T cog. It's a whole new world of cycling now for me. My new Road bike is now capable like gravel/mountain bike. Don't believe what the Google AI and manufacturer said, just do it.

Did what it was supposed to do.
I installed an 11-36 cassette on my Trek Domane so that I could handle the hills better. My Shimano 105 derailleur could only handle up to a 34-tooth sprocket. This extender did the trick. I had no problems with hanger alignment (I aligned the hanger before installing this). It went on simply. I didn't have to change anything on the bike. Problem solved.
