Geometry

There are a number of reasons to have a custom frame built for yourself. Among them is the fact that no two people are quite the same, and many of these people don't fit into the norm of production frames. Perhaps you want to extract that last bit of performance you feel your not getting from your present frame. Maybe your just looking for something special to express your individuality. Here at Moon Cycles I strive to attain that perfect union between man and machine. There is no standard geometry, each frame is different and everyone is evaluated on an individual basis. Most people who are considering a custom frame already have a pretty good idea what their proper seat tube size is. Where most of the problems occur is in the length of the top tube. It is possible to compensate for improperly fitting frames within reason, but you usually end up trading one problem for another. Sometimes you can compensate for a too long or short top tube by adjusting the seat position and the stem length, but this can result in an undesirable weight shift which alters the handling of the bike. Unfortunately you don't have much recourse for a frame that is too stiff or too flexible other than to buy a suspension post or stem or have someone modify the frame.

Ideally I like to meet with customers personally, take a few measurements, and go for a short ride to evaluate their current frame and riding position, but it is possible to design a properly fitted frame no matter where you are located, given that the required measurements are carefully taken by yourself or a knowledgable person at your local bike shop. Afterward we discuss what you like or dislike about your present bike and discuss options to arrive at a design which will fit your needs. The first of the measurements taken is your inseam which is the measurement from the floor to the crotch. This determines the seat tube length. Next is the overall height, this measurement and the inseam are used together to determine the top tube length. Finally the length of the forearm is taken to determine the proper stem length. Once these measurements are taken and tube lengths calculated, adjustments to the results are made according to the type of riding you will be doing. Once all of the details are ironed out a full size drawing is made which is used during the frame construction.

Another option to consider is a custom stem. Perhaps you prefer a more upright riding position to lessen fatigue on your lower back or past problems with your back prevent you from using a standard stem. In cases like these a light weight custom cro-moly stem can be made at whatever length and angle to accommodate virtually any riding position. The stem can be painted to match the frame or chrome plated.
