3D-Printed Titanium Cranks by Atherton Bikes - Worth It?

"The A.GR.TI cranks are a three-piece system - two separate titanium crank arms bonded to an aluminum spindle - built using the same 3D printers Atherton uses for their frame lugs. The inside of each arm features a ribbed, hollow lattice structure engineered to maximize stiffness while shedding grams."

"This isn't a pretty piece of CNC'd titanium dressed up in the trappings of luxury. It's a genuinely different approach to how a crankarm can be made."

"The modularity here is one of the most practical features Atherton quietly snuck in, with customization options including crank lengths from 150-175mm in 2.5mm increments, spindle diameter choices, and chainline options of 52mm or 55mm."

Atherton Bikes applies its signature 3D-printing and bespoke geometry philosophy to cranksets with the A.GR.TI model. The three-piece system features aerospace-grade titanium crank arms bonded to an aluminum spindle, with internal ribbed lattice structures engineered for maximum stiffness and minimal weight. The design includes closed outer faces for mud shedding and solid pedal thread areas for durability. Available in multiple configurations including crank lengths from 150-175mm in 2.5mm increments, spindle options, and chainline choices, the cranks are tested to Category 5 downhill racing classification. Starting at £845, they represent an over-engineered approach to crankset design.
