Shimano GRX 815 Di2 Bike

We’ve paired the ABLE with Shimano’s top-tier gravel-specific groupset, GRX Di2. It has all of the advanced electronic shifting capability from their best-selling Ultegra Di2 system, but in a burlier package to give it extra durability for gravel-specific usage. Small details go a long way here – and we’d argue that the GRX Di2 shift levers have the most comfortable and utilitarian brake lever design out there. You can brake and shift just as securely on your brake hoods as you can in your drops. When the speed is high and the terrain gets severe, the difference is noticeable, which is why Dirty Kanza champion Colin Strickland changed his ABLE build in 2020 from Ultegra Di2 to GRX Di2.

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.

We offer the ABLE in two stock colors -- Calvary Blue paint with Ecru decals, or Sport Grey paint with Mystique decals. Or you can choose the "Customize" option above and select from an assortment of non-stock PPG paint and decal options -- including Gloss, Matte and Harlequin -- for a $500 upcharge. And if you have a color in mind you don't find there, contact our customer support team so we can discuss the possibilities.
