Shimano Dura-Ace continues the heritage of road performance drive trains with the new 12 speed R9200 series. Shimano targeted the group squarely on the need of pro-tour riders and teams. With this intent, the've kept the gearing range inline with previous iterations, except for slightly expanding the range with the 12 speed rear cluster up to 11-34. Dura-Ace R9200 is only available as a Di2 option which mates perfectly with the ECHO. Shimano greatly simplified their Di2 transmission by going wireless from the shifters and then keeping a wired transmission from the battery to the front derailleur and rear derailleur. This eliminates one of our biggest pain points with the previous generation Di2, which is routing e-wires through handlebars and fitment of clunky junction boxes into the frame.
At the heart of the ECHO’s genetic code is pure unadulterated speed - the ability to transform from a road race thoroughbred to a versatile, agile gravel bike with a simple switch of flip chips at the front and rear dropouts. These eccentric chips and corresponding dropout design allow the rider to easily change the bike geometry, effectively changing the chainstay length and fork length by 1 cm. The difference transforms the bike from a road machine with 415mm chainstay length, 368mm fork length, 73-degree headtube angle, and tire clearance for up to 30mm, to a gravel bike with 425mm chainstay length, 378mm fork length, 72.5mm headtube angle, and 40mm tire clearance - all within a 10-minute switch of dropout chips. Pure road performance one day, gravel race-ready the next. One bike. No compromise.
The ECHO Stem is a fully integrated system designed in tandem with the fork. It conceals the cables while using a standard headset allowing the rider to easily swap stem lengths, and it works with a growing list of handlebars designed with integrated cables in mind. The ECHO stem system is the simplest and most user-friendly on the market today. The cables run through a channel on the top of the stem and are concealed by a faceplate, top cap, and the steerer tube. Headset adjustment is moved from the traditional position at the top of the stem to a threaded portion on the bottom of the stem, effectively increasing the steerer clamp length to provide headset preload, much like a threaded headset. The Echo stem is available in 6 sizes at 10mm increments (80-130mm) and is a -6 degree drop. Like all things designed by Allied, the ECHO stem is made in their Bentonville factory.
