Our best value in a Shimano-equipped ABLE is our GRX 810 build. You save significant cost by foregoing electronic shifting and going with traditional mechanical shifting instead. Shimano is the industry leader for drivetrain reliability and in the tried-and-true mechanical shifting configuration, Shimano is unmatched for “set it and forget it” precision. The GRX design is based on Shimano’s best-selling Ultegra 8000 road system, but built in a burlier package to give it extra durability for gravel-specific usage. This build includes Industry Nine GRCX tubeless wheels and an Easton cockpit.
The ABLE is a high-performance off-road machine that tilts more towards the “mountain skinny” side of the gravel segment. It prefers a big tire but keeps a short rear end - in fact, it’s the same as the ALLROAD at 420mm. This is achieved by the most striking feature on the bike - the elevated drive-side chainstay.
Getting a chainstay this short with high tire volume is a packaging exercise because the chainring, chainstay, and tire all compete for space behind the bottom bracket. On mountain bikes this problem is addressed by widening the bottom bracket -- but that affects Q factor in a negative way. When we made the decision to make the ABLE 1X-specific it opened the design envelope and ultimately led to the decision to elevate the chainstay. By moving it up and out of the way we could make it extremely wide resulting in an incredibly responsive ride.
While our award-winning ALLROAD is a Swiss Army knife for a majority of mixed surface riding, when the path gets rambunctious its road-racing genes might seem lacking. We found ourselves on occasion wanting a bike that was equally engineered, but felt more at home on steeper, rockier and more rugged terrain. It was from this desire that the ABLE was born. It’s lightweight, tight, durable and agile. You can point it in any direction and go.
The ABLE begs to be ripped around on singletrack, fire roads, hardpack dirt, and chunky gravel. Proven on the brutal roads of the 2019 Dirty Kanza where ALLIED athletes Colin Strickland and Amity Rockwell piloted their ABLEs to overall victory.
The ABLE comes standard in the stock color combination of matte black with silver logos. However, you can customize to the color combo of your choice for a $300 upcharge with any standard gloss or matte combo. If you have a color in mind you don't find there, contact our customer support team so we can discuss the possibilities.
