Mechanical shifting at it’s best. Eagle 90 delivers the dream, and then some. Featuring the same Full Mount derailleur architecture as it’s AXS Transmission siblings, it is unquestionably robust. And for the just in case, the derailleur body features replaceable outer and inner parallelogram links, skid plates, and a tool-free threaded cage assembly, making it the most rebuildable derailleur we’ve ever built. At the heart of the system is a sleek and sturdy forged aluminum E-MTB crankset, with a drive-unit specific T-Type chainring. Shifting under load is a signature of Eagle Transmission, and this is made possible on 90 with an XS-1275 T-Type cassette that features full X-Sync technology, and a premium double-click T-Type Actuation mechanical shifter.  For those inclined to DIY, mechanical Eagle Transmission has a revolutionary simple four step setup procedure: Prepare. Hang. Tighten. Route. Featuring no limit screws, no b-tension, and no guesswork. Built to take you as far as your imagination and body will allow, Eagle 90 Transmission provides riders with an unparalleled ride experience.

FEATURES: 

  • Tough and robust: Hangerless Interface and Full Mount give the Eagle Transmission derailleur a remarkably strong attachment, clamping around both sides of the frame itself and eliminating the need for a hanger. This super strong connection eliminates variance and improper adjustment across frame designs. It also eliminates hanger failures and allows the derailleur to rotate backward in the case of an impact.
  • The best mechanical shift under load. Period: Even with the added watts of E-MTB, the X-Sync tooth profile and 44 specific shifting points on Eagle Transmission cassettes allow you to shift with unstoppable precision under all the power you can muster. It’s the best mechanical shift performance under load there is. It’s not even a contest.
  • The world’s easiest mechanical setup: Eagle Transmission gives you an unbelievably simply setup procedure that will blow your mind the first time you do it. Just prepare, hang, and tighten. Installing a mechanical Eagle Transmission? The process is shared between Eagle 90 and 70, with one additional step to route and tension a standard shift cable. Either way, simply follow the steps and you’re ready to rip.
  • Mechanical Shifters: Eagle Transmission mechanical shifters combine decades of ergonomic refinement, delivering a positive mechanical shift. A new architecture routes cables parallel to the bar for pairing perfectly with stealth routed SRAM brakes. For riders who appreciate the satisfying tactility of the mechanical shift, this is love at first click. Speaking of clicks, Eagle Mechanical Transmission offers two shifter variants: Single-click shifters for mandatory usage with E-MTBs, and double-click shifters for human powered bikes. Shifter clicks are optimized to maintain best shift under load shift quality. 
  • The cleanest mechanical cockpit: To complete the cockpit, we sought to design a mechanical dropper lever that not only matched our Stealth brakes and Transmission shifters but offered optimized performance as well. Compatible with most cable actuated dropper posts, our dropper lever features ergonomics and routing based on mechanical Transmission shifting. Clean paddles, clean cables. Left and right.
  • Tough, reliable, game-changing rebuildability: The Eagle 90 derailleur is so durable that you’ll hopefully never need to rebuild it. But if it becomes necessary, it’s the most rebuildable derailleur ever. And all it takes is minutes to rebuild it, with three basic tools. Rebuild kits and skid plates can be found easily. All to help keep your Eagle 90 derailleur on the trails for a lifetime.

An absolute must for countertops used as workstations.
Style: 20W_USB-C, Size: 6FT
These were the best thing I did when we had to remodel and I added a large built in countertop. They are made well, and easy to install! They are very versatile since they are designed with both USB-A and USB-C ports along with the standard 110V plugs. I use these with my 3-D printers, laser engravers, computers, printers, and even a few coffee pots!

No issues, and no instructions.
Style: 20W_USB-C, Size: 6FT
No, you don’t need instructions, because the hole dimensions are in one of the photos. 4” x 1.73” is perfect. Plug it in and all of the ports in both that we bought worked perfectly.

Amazing. A bit of a job to set it up but worth it!
Color: Black, Color: Black
Excellent quality. Sturdy and strong. The screws that come with it are awful. Get yourself some different ones. Takes a while to set it up and get it all measured. I did it while I was setting up my new Flexi-spot E7 Plus standing desk. Wanted to get it all done at the same time. At first. I thought it might be overkill, but I am sooooo glad I did get this. Now my computer moves along with the desk. It looks great. I bet it has improved the air flow around my computer as well. Looks sleek and cool. I might have set it a bit too tight around my case and as a result I have to shimmy it to get it out of the holder if I have to do any work on the computers internals. But at least I know it's secure. My suggestion would be to leave a little bit of slack to avoid this in your setup. Maybe like a 1/4 inch would be ok. The pads should hold it in place anyway. May loosen mine up if I find the time. But it feels totally secure on the desk with no wobble or shaking. Great product. Also I'm a woman in my late fifties 😃and I was able to set it all up on my own. So don't be intimidated ladies, you can do it too. I also bought two of the ultimate set up cable management trays. Great products. Note for anyone from the Ultimate Setup company who might read this. Please provide better quality wood screws and some extra ones) I stripped three of the cheap ones that came with this. And it took forever to drill them in because they weren't strong enough. Then it would be perfect.
