The 3D-Printed Atherton A.GR.TI Cranks are Subtly Complex

Welsh mountain bike manufacturer Atherton Bikes calls their new 3D-printed titanium A.GR.TI cranks “the last set of cranks you’ll ever need.” Given that they carry a lifetime warranty and are gravity-rated, that may well be true, though with their hefty £845+ ($1,130+) price tag, they might more accurately be called “the last set of cranks you’ll ever be able to afford.” Read on for a quick overview of the Atherton A.GR.TI cranks.

Made in-house at Atherton’s facility in the small town of Machynlleth, Wales, the A.GR.TI cranks mark the company’s foray into off-the-shelf 3D-printed titanium products. Created from aerospace-grade 23 titanium, they have a sleek, timeless exterior that hides an intricate inner structure with internal bracing and fine-tuned wall thicknesses. Rather than being machined or forged, they’re “sculpted from the inside out.” As a reference point, a 165mm crankset with a 52mm chainline weighs 506 grams, including the axle and hardware but excluding the chainring.

The A.GR.TI cranks are available in a commendable 11 lengths in 2.5mm increments from 150mm on up to 175mm. They’re also offered in three finishes—raw, burnished, and tumbled—to suit a wide variety of aesthetic preferences. In addition, Atherton lets buyers choose from three chainlines (Trail/52mm, Trail Wide/55mm, and DH/56.5mm) and two axle diameters (28.99mm and 30mm). With their modular design, you can buy cranks to suit your current chainline and swap when a future need arises. A self-extracting crank bolt makes installation straightforward with an 8mm Allen key, and with an 8-bolt direct mount standard, there are plenty of chainrings available from various companies.

Low-profile crank tips mean a 5-6mm reduction in material when compared to conventional designs, slightly reducing the likelihood of strikes. In Atherton’s words, “Every contour is shaped with purpose, removing unnecessary material where we can, reinforcing key zones where it matters most.” The video below offers an in-depth look at the design and manufacturing process:

As mentioned, the A.GR.TI cranks are priced at £845 in raw finish (burnished and tumbled add £30 and £50, respectively) in the UK market, including local taxes. Buyers in the United States don’t need to pay UK taxes, so the price is $922.46 (add $30 for shipping), excluding import taxes and duties. Atherton says it can take 4-8 weeks for cranks to be ready to ship after ordering. They’re ready to purchase now, and full details are available over at AthertonBikes.com.
