Allied Echo Rival AXS | Road Bike

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 to a gravel bike - 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 to completely conceal the cables while still 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 system is the simplest and most user-friendly on the market. 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 that effectively increases the steerer clamp length to provide headset preload, much like a threaded headset.
