The New Allied Echo Transforms from Gravel to Road with Reversible Dropouts Allied introduces a more technically advanced take on the all-road concept

One bike to rule them all. That’s the aim with the new Allied Echo, which introduces a flippable chip into the dropouts to quickly switch between gravel and road geometries.

This bike, the third gravel bike in the Allied lineup along with the Able and Allroad, is all about speed. In its road form, it features 415mm chainstays, a 368mm fork, a 73-degree headtube angle and 30mm tire clearance. Reversing the flip chips in the fork and the rear dropout changes the chainstay length and fork length by 1cm, which is enough to significantly change the bike’s geometry—while keeping a focus on speed. In gravel geometry mode, it features 425mm chainstays, a 378mm fork, a 72.5mm-degree headtube and 40mm tire clearance.

Allied says the transformation takes just 15 minutes, so if you have a couple sets of wheels this bike could be even more of an all-road style bike than those which offer 35mm or more of tire clearance while trying to balance between road and gravel geometries. While people who like to explore deeper gravel terrain or more technical terrain might miss having a larger tire clearance, 40mm paired with a more aggressive gravel geometry is perfect for the gravel racer.

Gravel racer Colin Strickland has been riding the ECHO.

But Allied hasn’t just designed the frame; the stem, called the ECHO stem, has been designed in conjunction with the fork to hide cables internally in a user-friendly way. It runs cables through a channel on top of the stem, concealing them with a faceplate which also covers the steerer tube. Rather than adjust the headset at the traditional spot atop the stem, the ECHO stem moves this to a threaded portion at the bottom of the stem. The stem, made in Bentonville, Arkansas, just like Allied’s frames, comes in five sizes from 90mm to 130mm in 10mm increments, all in -6 degrees.

The ECHO stem is made by Allied and routes the cables through the top of the stem, beneath a faceplate.

Complete builds start at $6,000 for a SRAM Rival eTap AXS build, going up to $8,000 for a Force AXS eTap build and $10,465 for a Red eTap AXS build. Frames come in six sizes from XXS to XL.
