So you're ready for a custom bike? Give me a call:
we can talk about the bike you've always wanted. Before you pick
up the phone, here are a few things to consider:
general overview of bicycle anatomy and geometry.
are some of the most important specifications to consider when designing
your bike. It is very important to choose these measurements in
accordance with the specifications of the components to be used
on the bicycle. Some examples: Stem length/rise; crank length; tire
size; suspension fork height, rake, and travel. If this jargon seems
overwhelming, don't worry, it is ultimately my job to make sure
all of this is right. We can work through it easily through conversation.
If you are a well-versed student of the dynamics of the bicycle,
please forgive the monotony, send me some numbers and let’s
horizontal distance from the center of the headtube/toptube junction
to the center of the seattube. Considered by many to be the most
important measurement of a bicycle. . This measurement should be
chosen in consideration with the stem and seatpost options used.
This will ultimately determine the cockpit length, and therefore
the riders position on the bike.
horizontal distance from the center of the handlebar to the center
of the seat. The ultimate determinant of how the rider fits on the
distance from the center of the bottom bracket to the center of
the rear axle. A short chainstay produces a quick, responsive ride,
and makes it easier to pull up the front end, as well as getting
around tight switchbacks. Freeride and Jumping style bikes generally
have shorter chainstays. A longer chainstay produces a very stable,
smooth ride, excelling in situations such as fire road descents.
Bottom Bracket Height
vertical distance from the center of the bottom bracket to the ground.
A high bottom bracket produces good ground clearance and can make
the bike easier to bunny-hop and get over obstacles. Low bottom
brackets produce a low center of gravity and make the bike corner
distance from axle center to axle center. This measurement is most
greatly affected by toptube and chainstay lengths. Short wheelbases
steer quicker; longer wheelbases are more stable at high speeds.
This is one of the most crucial measurements when designing a bike
because it cannot be significantly manipulated with different components.
