The best value in a Shimano-equipped Allied ABLE is the 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.
Building 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. By moving the ABLE chainstay up and out of the way we could make it super-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.
