Machinists extraordinaire, Paul Components Engineering, have reached into the way-back machine and decided to bring back the 100% Pure Cranks. This time around, the cranks will feature an updated design with a 3-bolt direct-mount chainring spline and self-extracting crankbolts.
The Paul Comp Krëw says that it was Paul’s idea to bring these beauties back, but told the gang that he wanted to bring them back with a square taper. They were cautiously optimistic. That’s the benefit of having your name on the building: you get to do what you want.
The team started testing the prototypes and were surprised to find that they could really hone in the q-factor and chainstay clearance of their steeds. It was just as simple as swapping in the right bottom bracket spindle length, just like the good ‘ol days.
They were able to get the chainring close to the chainstay to get the right chainline in the bigger rear cog using chainring offset (0, -3, and -6).
The crank arms are CNC machined in Chico, California, using 2024 American alloy. This allows for “the removal of a lot of material for an elegant design”, while retaining optimal strength and stiffness.
These beauts are available now.
