The Liberation Fab Empty Bee yoke allows framebuilders to create a tasty chainstay sandwich with 2.6” tires on one side and up to 34t boost chainrings on the other. A minimum chainstay length of 420mm is recommended. This yoke is additively manufactured out of 316 stainless steel and is an experimental design.

Currently only sold pre-mitered for T47 51mm bottom brackets and Ø19.1mm x 0.9mm wall chainstays.

There may be fitment issues with some Shimano boost chainline cranks.
