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.

One of the best purchases I've made in a while.
Format: Hardcover
As a devoted fan of the show from almost the very beginning, I followed all the interviews, sneak peeks, and DVD commentaries aggressively, so I thought I knew a good bit about every aspect of the show, from its influences to its creation process to little trivia bits about the finished episodes. I told myself I didn't need the art book because it would tell me little about Avatar that I didn't already know. For a while I was able to hold off buying this book, but the art in Avatar is so beautiful that I finally broke down and got it, telling myself that I might as well dish out twenty bucks to have a nice hardcover Avatar book to add to my collection of flimsy cinemanga and Earth Kingdom Chronicles paperbacks. Now I'm writing this review to tell every fan out there who has had even a minute's hesitation in buying this book: DO IT.
Avatar: The Art of the Animated Series covers everything you could dream of wanting to know about the show. I should have known Bryke would never do anything halfway. I was blown away by the obviously intense amount of effort the creators put into compiling such a thorough and well-put-together inside look at the creation process. They explain everything about Avatar's production, starting with their very first fateful meeting and taking fans all the way up through the end of the epic series. It's so neat to read about all their inspirations (especially if you're an anime fan; you'll probably recognize a lot of names) and some of the difficulties they had to overcome in order to make the show what it is today. It is a fantastic read from cover to cover.
As you can tell when you use Amazon's "look inside" feature, the creator commentary is arranged in paragraph format with bold letters to tell which creator is speaking. They actually go into a lot more detail than I thought they would about almost everything. They spend a lot of time talking about the development of characters: their personalities, design characteristics, models, and any changes that were made and why. (Plus it's really neat to see the way some of your favorite characters looked like originally!) They mention the animals, settings, voice acting, martial arts influences, weapons and technology, and all sorts of other things, some that you may not even necessarily have thought about much before, like color schemes and drawing styles. I learned a lot of really neat things about the process behind Avatar's animation and about the Korean studio that did such a beautiful job animating the series.
The thing I like most about this book is the great variety of art it showcases. There are original character concepts by various crew members, background sketches and paintings, real storyboard action sequences, martial arts references, detailed clothing and weapon designs, descriptions and illustrations of Avatar-verse animals, screenshots from the show and the original pilot episode, press and/or promotional art, and even some photos Mike and Bryan took on some of their trips to places that inspired the layout of the Avatar universe. And to top it all off, there is at least a one-page spread for each one of Avatar's 61 chapters that highlights some of the strongest points in each episode, whether it's new characters, locations, technology, action sequences, or a combination of several of these. Needless to say, this book is a must-have for all Avatar fans. Whether you're a casual fan who just happened to fall in love with the art (and there is plenty of it in this book, all amazing quality despite the fact that much of it is simply sketched) or you're a die-hard Avatard who wants to know everything about everything, trust me when I say that this compilation is worth every penny and more.
As for the packaging and shipping, I have very little to say - the item was wrapped adequately and arrived when it said it would. No problems there. The only minor (and I do mean minor) problem that I had was that one of the corners was bent when it arrived. It probably would have happened anyway, though, through regular use, so it's not really something to complain about. Everything else was fine, and the price is excellent given the durable binding and beautiful thick pages (not to mention the content). I know I've said this so many times that it's probably starting to sound old, but if you want a good look behind the scenes of the greatest cartoon of our generation, this is it. Other creators, take note: this is how TV series art books should be.

Spellbinding
Format: Hardcover
This is a wonderful art book for a spellbinding animation series. Making the series took 6 years, hundreds of artists, and hundreds of thousands of drawings. This book showcases a selection of some really beautiful illustrations.
There are loads of character and background designs inside, in sketches and in their finished coloured form. The main characters like Aang and others come with cool animation sequences created with pencils. Also included are many of the discarded concepts which were difficult to animate or doesn't suit the story. Appa had some really awesome spiral horns but were discarded, unfortunately. The character drawings are superb. Just by looking at their different expressions you can pretty much guess their characteristics.
Besides the characters which includes the town folks and soldiers, there are also drawings for many miscellaneous stuff like storyboards, airships, hybrid animals, wanted posters, promotional posters, chibi (or super deformed) style and random doodles from meetings.
Did I mention the background paintings? The world created is so beautiful!
The whole book is annotated heavily by Bryan Konietzko and Michael Dante DiMartino. They talk about everything on production, from creating the pilot episode to Nickelodeon approving the final season. You can see and read about their influences and inspiration everywhere, from Buddhism, Studio Ghibli, Gainax, Chinese martial arts, etc. It's very interesting to see how they apply what they learned from research to their drawings and animation.
This is a fantastic art book for the series and fans, which should appeal to anyone who hasn't watch the series. Good art appeals to all.
Highly recommended!
(There are more pictures of the book on my blog. Just visit my Amazon profile for the link.)
