Seat Tube Angle (STA)
is the angle from the ground to the seat
tube, measured from bottom bracket to top of the extended
seatpost. Steeper seat tube angles put the rider in a more
powerful pedaling and climbing position, but too steep will
cause awkward pedaling and steering dynamics.
Reach (R)
is the horizontal distance measured from the bottom
bracket to the head tube. It determines how the bike fits while
the rider is standing up. Shorter reach makes the bike more agile
and playful. Longer reach provides a roomier cockpit.
Bottom Bracket Drop (BBD)
is how far below the height of the
axles your bottom bracket is. More bottom bracket drop means a
lower bottom bracket, which is critical in determining your centre
of gravity. More bottom bracket drop (lower bottom bracket)
makes cornering easier and increases the feeling of being “in”
the bike, while less bottom bracket drop (higher bottom bracket)
makes it easier to avoid pedal strikes.
Head Tube Angle (HTA)
is the angle from the ground to the fork.
A slacker head tube angle allows the bike to plow over obstacles
more easily, while a steeper head tube angle makes the bike
respond faster to steering input.
