Compact Road Frame
Compact Litespeed frame sizes are based on the intersection of the
virtual top tube and seat tube. The actual size is based on the virtual
seat tube length. The virtual seat tube is measured from the center of
the bottom bracket shell to the point where the virtual top tube meets
the centerline of the seat tube extending into the seat post region.
The virtual top tube is the horizontal line parallel to the ground and
extending from the point at which the centerline of the top tube meets the
centerline of the head tube.
Standard Road Frame
All Litespeed standard road frame sizes are measured in a center to top format
from the center of the bottom bracket shell to the intersection of the centerline
of the seat tube and top tube.(A) Top tube lengths on our road frames are taken from
the intersection of the centerlines of the seat tube and top of the top tube to the horizontal
intersection on the centerline of the head tube.(B)

Standard Mountain Frame
All Litespeed mountain frames are measured from the center of the bottom bracket
shell to the intersection of the top of the top tube and the centerline of the seat tube.
Top tube lengths on mountain frame are taken from the intersection of the centerlines of
the top tube and seat tube to the point at which a horizontal line intersects the
centerline of the head tube. NOTE: The intersection of the horizontal and centerline of
the head tube will be at the bottom of the head tube but on its centerline in the fork region.
Time Trial Frames
The Saber and Blade are measured from the center of the bottom bracket to the top of
the seat tube, but on the Blade 10cm have to be deducted because of the extended seat tube.
The top tube length is measured from the centerline at the top of the seat tube to the
point at which a horizontal line meets the centerline of the head tube. NOTE: The horizontal
intersection at the head tube may intersect at a point in space above the actual head tube
but along its centerline.
