Goal

More of a design excersise and just a fun project rather than a performance machine. A fire road commuter? An urban drunk bike? A long haul adventure bike? Who knows?

Adjustable BB Height

A Phil Wood 1/2 link eccentric BB will provide bottom bracket heights within a 6mm range. A subtle tuning feature that could really help the bike. At the very least it will give the bike a single speed option.

Headshok

80mm Cannondale Headshok DLR. A nice little unit with rebound and lockout adjustment.

Geometry Change with Fork Travel

  • @ 60mm Ride Height - 71 HA, 285.8mm BBH


  • @ 80mm Ride Height - 70 HA, 292.5mm BBH
  • @ 0mm Ride Height - 74 HA, 262.2mm BBH

This is uncharted territory. I have to start with something. This seems as close as anything.
