Our best-selling ABLE is our SRAM Force AXS build. It features the same wireless shifting and electronics platform as the cost-is-no-object Red AXS. But by foregoing Red’s costliest upgrades -- think ceramic bearings, extraordinary finishes, and featherweight hardware (the weight difference between groups is 300g total) -- you save a mint.
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.

A 1x drivetrain is quickly becoming the industry standard for gravel: You’ll always find the right gear at the right time. The ABLE is 1x-specific, which allows us to elevate the chainstay for tire clearance without resorting to a super-wide mountain bike-like Q-factor.
The ABLE is designed around a 700x42c: This is the tire size we recommend for optimum BB height and steering (remember: tire size affects steering geometry.) But if you ride in really chunky rocky terrain the ABLE can adapt with 650c wheels and tires as big as 47mm in the rear and 55mm in the front.
Four sets of bottle mounts -- one on each side of the downtube, one set on the seat tube, and a top tube mount ideally suited for a bolt-on bag.
