When Paul suggested we bring back our classic 100% Pure Cranks, but with an updated design featuring a 3-bolt direct-mount chainring spline and self-extracting crankbolts, we got excited. When he suggested JIS Square-Taper for the bottom bracket, we were like, “Uh, square-taper in 2025? I dunno…”
But a funny thing happened once we started mounting and testing prototypes. We realized we could really fine-tune the Q-factor and chainstay clearance of the crankarms via BB spindle length, then we could get the chainring nice and close to the chainstay for better chainline in the bigger rear cogs via chainring offset (0, -3, -6). Q-Factor nerds rejoice!
These crankarms are CNC machined in-house from ultra-strong 2024 American alloy. This allows us to remove a lot of material for an elegant design, while retaining excellent strength and stiffness. In stock now on our website or from your favorite local bike shop!

Yes! There is a Santa Claus! Finally somebody making cranks at 180mm!
Note, they are square taper. If you recall, Campagnolo used to produce Record alloy cranks during the late 1990’s / early 2000’s in 180’s.
