Frameset Geometry Notes

  • All geometry measurements subject to change without notice.
  • All measurements are in centimeters, unless otherwise specified.
  • Top Tube Length, Effective: Measured from the intersection of the head tube and top tube centerlines, horizontal back to the seat tube centerline.
  • Stand over height measured mid-way along the length of the top tube.
  • Toe overlap:  Because the Travelall often has large tires, many of the sizes will have some toe overlap.  Make sure you are comfortable with this before ordering.  Questions?  Contact the Beekeepers.

 

Specifications subject to change as components and technology improve.  If you have any critical measurements for your cycling enjoyment, let the Beekeepers know before placing your order.
