philosophy on bicycle design
Each JESTER is hand built and custom designed to fit both the owner's individual physique and the owner's particular needs. You as an individual human being, are unique, there is no one else exactly like you, either in personality or physical form. So why would you, as a cycling individual, ride the same bike as countless others do in riding an off-the-shelf model?
A bicycle's beauty truly is in its ride. it should be well finished and a beauty to behold, but if it rides like crap, what good is it? I believe that if one is going to build bicycle frames, then one ought to do the very best possible job of it.

All Jester frames are hand built by Jody Thomas Lee. Jody combines a unique blend of talents in his frame building meticulous craftsmanship high degree of technical skill mastery of metal joinery an artistic eye a scientific mind anthropology background provides rare insight into human physiological variation material science studies utilized in bicycle frame design.
It Jody's love of bicycles and of bicycling, combined with his inquisitive mind and experimental nature that lead him to frame building. Frame building lead Jody to Julian Edwins, (who had an earlier influence on Jody's thoughts on bicycle design)
Jester frames are built in accordance to the Edwins formula of custom frame design and fabrication.
The Edwins Formula was developed by Julian Edwins based upon extensive research into human kinetics and modern materials Edwins frames were built during the 80's and early 90's renowned for delivering an unequaled combination of performance, responsiveness and comfortJulian Edwins has since retired from frame building and has chosen Jody to continue building frames in his tradition.
There is no singular factor that leads to this objective. Rather, there are several equally important factors whose cumulative effect results in the manufacture of the very finest bicycles. These are:
Design to fit the rider
Design to fit function intended by rider
Use engineered material that best meet needs of bicycle
construction at the highest level
Select each individual tube on each frame for each rider
Design each frame joint optimal strength and rigidity
Use metal joining methods that ensure optimal strength and rigidity
Maintain tolerances and quality standards that best meet the
needs of bicycle construction at the highest level
Visually, the finished product should reflect both the
quality of the ride and the quality of the workmanship and
instill pride of ownership and confidence in its rider
The Result: Lightweight, strength, rigidity, resiliency, comfort, control, efficiency, beauty, function and speed.
Every JESTER frame is:
A silver brazed
Can be built with lugs
Can be built lugless-fillet brazed
Construction techniques, tolerances and material choices ensure the greatest possible joint strength available of ANY joining method each joint on JESTER frame is designed and crafted to produce greatest possible amount of strength and rigidity each joint on JESTER frame is designed and crafted to be free of stress risers joinery like this can only be achieved by hand work, it is not possible with production building techniques
The down tube and seat tube are each mitered to on another (double mitered) giving nearly twice the strength and rigidity over the more commonly used single miter method.
On a JESTER, all of the tubes go through the bottom bracket to the inside face of the shell in both lugged AND lugless designs with lugless frames, piercing the shell provides up to SIX times greater joint strength than the more commonly used method of mitering to the outside of the shell
Types of Tubing
Today, there exists a great deal of confusion about bicycle frame materials.
At JESTER Hand Built Bicycles, the science of metallurgy is used as a guide for
selecting frame tubing.
Having researched and experimented with a variety of materials, JESTER currently recommends two different types of micro-alloyed steel tubing and one type of stainless steel tubing. All steels used are high strength and are chosen because they retain their high strength after joining. These are produced by a number of manufacturers as follows:
Nickel-chromium steel marketed and sold as:
Podium HR by Excell
Vanadium steel from a number of different manufacturers such as:
Nivacrom™ by Columbus
Thermacrom™ by Columbus
Zero 18MCDV6HT by Dedacciai
Zero Uno 18MCDV6 by Dedacciai
Cr-Mo-Va 16MCDV6 (formerly Super Vitus 983) by Vitus
Stainless steel marketed and sold as
Nicromox™ by Columbus
of these tubing manufacturers markets their tubes in a variety of tube sets
and as individual tubes, and under a variety of quaint names.
There are some subtle and not so subtle differences between the various
alloys of vanadium steels offered.
