Your cart is empty.If you're running a dramatic 11-speed cassette with Shimano Durce or Ultegra rear derailleur, it's best to upgrade the stock direct mount of the Wolf Tooth Roadlink DM. In this way, you can quickly flick the shift lever and maintain the stock level of chain wrap and crisp shift without feeling anything unstable when the chain moves up and down. Wolf Tooth, optimized the Roadlink DM to a wide range of 11-speed cassettes. Expand your gear range and boost your cycling field of vision than ever before, saving energy in difficult climbing.

I bought this to move my sram derailer further out to fit a 40t. Now this is too far away to engage my two biggest cogs.

This is the substitute option for increasing your rear mech range.This replaces the mech hanger hinged section on the r7000 rear mech, that actually mounts to the mech hanger...... Hope that makes sense.It requires removal of the original arm and small shim from the mech and this DM link replaces them both.The effect is to drop the mech from it's original position and open a broader potential range of gears.I bought to increase my rear range on a r7000 set up from 11/34 to 11/40.In reality ...The rear mech will accommodate 11/36 without use. ..A pilo replacement mech hanger with a slightly longer drop and tweak to the B-limit screw has delivered the 11/40 range " anyway " ...The DM link will actually mean I can potentially run 11/42 or11/46 if the 11/40 proves insufficient.I hasten to add, this is on a 2x set up.For completeness, I am running...R7000 shiftersR7000 front mechGRX 600 48/31 cranksR7000 rear mechPilo mech hangerSLX 11/40 cassetteAll gears options available cleanly from either front ring.

11-34Tに対応のRD-RX810、11-42Tに対応のRD-RX812でフロントシングルする際にロー側でプーリーと干渉してチャラつくのを抑える為に購入。全くチャラつかなくなって安心できるようになりました。ただしアルミなのでディレイラーハンガーが折れるような衝撃が加わると本製品が壊れる可能性はあると思うので、シマノ純正のほうを六角レンチと一緒に携帯している。

Worked great for 11 speed dura ace di2. If you want to keep the dura ace rear mech but want big cassette, this is the way. You might need to replace chain with 1-2 extra links depending on your current chain. Or not.

Since most of the bikes for sale these days come with compact cranks or "one bys", I needed a solution to get lower gearing to compensate losing the triple geared cranks that I've grown accustomed to over the years. This enabled me to use an 11-40t cassette on my Trek Domane. Very Sweet!

フロントシングル化に伴い，リヤディレーラーをシマノGRX RD-RX812，リヤスプロケットを42tにしました。理論上はそれだけでうまくいくはずなのですが，特にトップ側はテンションボルトやワイヤーの張りなどを調整して変速が安定しませんでした。ディレーラーの位置を変えたらよくなるのではないかと思いこの商品に行きつきました。結果はばっちりです。

Easily installed, the RoadLink DM notably improved the RD-8000 GS shifting smoothness on the SRAM PG-1170 11-36T cassette installed on my bike. I readjusted the B-screw by loosening it. Now, my rear derailleur is shifting as smooth as if equipped with a 11-34T cassette.

The link was super simple to install. Torque settings would have been nice, but standard 8-10nm works. I had tried the RoadLink before with an Ultegra mech, which didn’t quite work on that TCR. Tried this Direct Mount version on my gravel bike and it lets me run an 11-40 with the b-screw all the way in. Previously I could use the same cassette, but the b-screw was not making full contact with the mech body. This RoadLink DM solves that elegantly and simply. I could probably go up to a 11-44 even.

Will update if anything is worthy of demoting. Used this with and Ultegra RX r800 and an XT 11-42 cassette. The RX is rated to hit 34-36. I did not need to extend my b-screw. Just a slight limit adjustment and b adjustment. You remove part of the derailleur and replace it with this.UPDATE: Zero issues. This thing has been put through as much of "the wringer" as possible for an RD upgrade. Great tool for a cheap and effective upgrade.

Used the Road link DM with Ultegra RD-RX800 rear derailleur (the one with a clutch) to shift on a 11-40 cassette and it improved the overall performance significantly. To be clear, the medium cage RX800 derailleur can already clear 40T with careful b-screw adjustment, but the shift performance for smaller cogs is suboptimal due to reduced chain wrap. I also found it became quite sensitive to slight cable tension difference so to dial in perfectly is a bit tricky.This b-link from WTC improves chain wrap by offseting the position of the derailleur so that the b-screw not longer needs to be almost maxed out to clear the largest cog (yes it's very important to readjust the b-screw after installation) and the increased chain wrap helps with the shifting performance. The Road link DM is very well made. Still a bit pricey for what it is but it's a simple and easy solution.

High quality alloy, machining and finish as with all Wolf Tooth products. This roadlink allows me to run a 1x with a 10-42 cassette with my Ultegra RX rear derailleur. Keep in mind that while this does allow you to run a larger max cog than is spec’d by the derailleur manufacturer and still keep decent chain wrap, it doesn’t increase the actual chain capacity of the mech, which is dictated by the cage length. I’m sure I voided a warranty on the RD with my setup but the gear range is well worth it.

I got an Ultegra R8000 to try to run a 40t cassette without resorting to "bandaids" like a normal Roadlink or having to modify cable pull to use a mountain derailleur. It did clear the 40t without even maxing out the factory B-screw, and it shifted surprisingly well for having 2"+ of free chain in smaller gears.Jumped on this to see if I could really run a 10-42t XD cassette and free up some range. First thing I notice when I tighten up the bolts- without touching the B-screw from where I had it, it's now got about as much free chain in the 40t as I had in the 11t before! Back that way off, and it's got probably 2 more teeth wrapped in the big cog, and free chain in smaller cogs is maybe 25% more than a normal road cassette, rather than 3-4x as much.Like everything else I've gotten from Wolf Tooth, it looks and feels quality. It's not super-cheap, but then it's relatively low-volume, US-made, and I don't think the price is high either, given that. Well worth the price of, say, a half-decent chain, IMO.
