The human body is a work of art. With precise sizing, your bike will fit and ride like art, too.
In order for your bicycle to truly be yours, it must be designed, and built based on a direct relationship to your many individual measurements. This service is often not provided at the local bike shop. The way too many bike shops size the bike is based on stand over height…you stand over the bike’s top tube, lift the bike up into your crotch, and if there is about 2 ½” to 4” of gap between the tires and the floor, it is supposed to fit. Although this method does indicate whether or not you will high center, it indicates nothing about your flexibility, your ability to comfortably reach the handlebars, to spin the pedals efficiently, or even to breath effectively…all of which are necessary for your chosen sport to be a good work out, and fun. In fact, if your bike does not fit properly, damage to your joints could be the result. Few local bike shops offer individual sizing. In the shops that do, a stranger takes your measurements, usually in a public area like the show floor, or the service department. Most people do not prefer having this done in public. For this reason, we offer you a method to get these needed measurements in the comfort of your own home, with the assistance of a partner of your choosing. The actual measuring method will take about 30 minutes to read and carry out. Accuracy is most important and the provided instructions are very specific…follow them exactly, and you’ll be very pleased with your bike’s fit. When your measurements are received, we will enter them into the Accufit program, and determine the size, and angles of your frame, length of stem, as well as the size of your handlebars, cranks, and wheels. Now we can tell you whether or not you will need a custom, or a semi custom frame. What is the difference? Semi custom frames are mass-produced with specific measurements, and angles that fit most people. Custom builds are for those who desire a more specialized bike, of have a body shape that is not so common. At the conclusion of this stage, you will receive an email of our results that contains your measurements, our frame size recommendation, and even a basic picture of your body position on the bike. Take some time, consider the picture of the riding position…is this a realistic position for you? Do you truthfully believe that you are flexible enough to ride in this position? Comfortably? Once you are satisfied, will we put together your bike package with the quoted price. When payment is received, everything will be ordered, and an estimated time of arrival will be emailed to you. When we receive parts, and during the assembly, you will be sent daily emails with pictures of your bikes progress until it is shipped to you.
Sizing Method/ Instructions We use the Accufit sizing and fitting system developed by bike fitting guru Bill Boston. The Accufit system is the most complete bike sizing and designing system . In the Accufit system, your bodyto bike relationship is looked at from the perspective of being a complex combination of levers. To ride as an efficient system, the specific length, strength, and flexibility of your body's levers is considered, as well as your ability to take in oxygen, and pump blood through your body. All of these variables must be considered in making the final sizing determination. The final consideration to consider is aerodynamics. The following instructions and questionnaire will provide us with the needed measurements of all the key parts of your body. In order to build the perfect bike for you, accuracy in measuring is very important. Please take your time, measure all the needed body parts several times, answer the questions realistically, and by all means, email or call us if you have any questions. Please do the following steps:
Carpenter square Steel tape measure Small level (optional, but really helpful) Roll of masking tape Kitchen stool or piano bench, or any seat with a flat surface, at least as high as your knees so that when you are seated your knees are at the same height or slightly lower than your hips Any round object about the diameter of your bike handlebars, such as a broom stick or dowel Pen or pencil (regular size) Paper Washable marker (optional)
Stand against the wall with the masking tape centered between your shoulder blades Place the carpenter square, short side, gently on your head, with the long side up the wall. Have your partner mark the masking tape at the bottom of the square. Mark this line "H". Measure from the floor to this mark and record as "H". You can make measurements in inches or centimeters.
Your sternal notch is the little dip between your collar bones at the base of your throat. Turn to face the masking tape. Place the level gently in your sternal notch and step forward until the level touches the tape. Have your partner make sure the level is level to the wall and mark the top of the square. Mark this spot "SN". Measure from the floor to this mark and record as "SN".
With your arms hanging loosely at your sides, have your partner feel from the back of your shoulder for the top of your shoulder blade. Your partner should be able to feel the bony ridge opposite of your collar bone if your shoulder muscles are relaxed. Have your partner follow the top of your shoulder blade outward until it ends. With the washable marker, have your partner mark a vertical line along the outside edge of your shoulder blade. Repeat this process for both shoulders. With the position of your shoulder joints established, grasp the dowel or broom stick in one hand. Extend your arm out at your side until horizontal, with the thumb side of your hand pointed up and the dowel vertical. Have your partner assure that your arm is level and that the dowel is vertical. Have your partner measure the distance from the line that locates your shoulder joint and the center of the dowel. Record this length as "AL".
Grip the dowel in your fist. Place your arm in arm wrestlers position on a table.
With your forearm vertical, and the dowel level, have your partner measure the distance from the top of the table to the bottom of the dowel. Record this spot as "FAL"
Have your partner locate the two vertical lines drawn on the back of your shoulders during "Measure your arm length" Stand straight with your shoulders relaxed and arms hanging loosely at your sides. Have your partner measure the distance between the two lines. Record as "SW"
Place the flat seat of your choosing next to the tape on your wall. Measure the height of the top of your seat from the floor. Mark this spot "FSH". Sit on the seat with your back to the tape and your buttocks against the wall. Do not flex your buttocks because doing that will change this number. Place the square gently on top of your head. Have your partner mark your seated height on the tape at the bottom of the square. Mark this spot "SH" , measure up from the floor to the mark, and record.
Angle your seat 45 degrees to the tape. Sit square on your seat so that your legs are 45 degrees to the tape. Again, keep your buttocks and thighs relaxed. Do not flex. Place the square gently in the crease created by the top of your thighs and your groin, as close to your abdomen as possible. The square will be angled along your side, toward your elbow. Have your partner mark the tape at the bottom of the square. You may have to adjust your position on the seat in order for the square to touch the tape. Mark this line "STH", measure up from the floor to the mark, and record.
This one is a bit tricky, but take the time to get it right. While seated, feel for the center of your right knee cap. At that height move your finger to the outside of your knee halfway between the front and back of your knee. You are trying to find a dip between the bottom of your femur and the top of your shin. When you have found this spot, flex your knee. Your finger should not move up or down as you move your shin back and forth under your thigh. If your finger moves, reposition your finger until you find the spot where your finger does not move. Mark where the bottom of your finger rested with a washable pen. Stand next to the tape. Have your partner position the bottom of the square next to the spot marked on your knee. Have your partner mark the tape at the bottom of the square. Label this line "RKH", measure up from the floor to the mark, and record. Repeat all of the above steps for your left leg and mark, measure and record as "LKH"
Place your heel against the wall Have your partner measure the length of your foot Record as "FL".
Have your partner locate the widest part of your foot at the base of your big toe. Mark with a small line. Have your partner locate the widest part at the base of your little toe. Mark with a small line. Have your partner draw a line across your foot with the straight edge from the lines at the edges of your foot. Measure the length of this line and record as "FW".
Have your partner mark the mid-point of the line drawn across the width of your foot. Place your heel against the wall. Have your partner measure the distance from the wall to the mid-point line along the little toe side of your foot. Record as "FB"
This is all of the information we need from you in order to recommend the correctly sized frame and components for you. We will plug your numbers into the Accufit program to generate all of the necessary measurements for your proper bike set-up.
