Not sure what size bike you need? No worries, we’re here to help. Before we can do anything though, you (and a helper) need to get some measurements that you can send to us. It is crucial that you try to get these as exact as possible. Also, we’ll ask you some questions about the type of riding you do, your experience level and preferred riding style.
Sit straight up on a stool or bench that is about the same height as your lower legs (you should not feel like you are sitting too low or too high) with your back and pelvis against the wall. Your buddy should place the end of the level on top of your AC (Acromioclavicular) joint. It’s the bony-feeling bump on top just a few inches in from your arm.
Have your buddy measure from the bench to the bottom of the level. Make sure the level stays straight. It’s always a good idea to measure both sides. This will tell you if you aren’t sitting straight or are more than a little asymmetrical. Use the average of the two measurements.
While sitting on the same bench and holding a seat post or something similar like a piece of pipe, have your arm at your side with your forearm parallel to the ground.
Have your buddy measure from the bony point on your elbow joint to the center of the post as pictured. Same thing applies here, take the measurement on both sides and use the average.
Sitting in the same position and still holding the tube perpendicular, extend your arm out, with your entire arm parallel to the ground.
Have your buddy measure from the pivot point of your arm (slightly below the line of the AC joint), to the center of the tube as pictured. Again,take the measurement on both sides and use the average.
While still sitting on the bench with your back and pelvis straight against the wall, hold the level across your kneecaps. Keep your feet and legs apart about 8″ as you did earlier.
Have your buddy measure from the wall to the edge of the level that is facing you. Take the measurement on both sides and use the average.
LOWER LEG LENGTH
Still sitting, place the level on the top edge of your kneecaps.
Have your buddy measure from the floor to the bottom of the level. Again,take the measurement on both sides and use the average.
Yes, this measurement is awkward in more ways than we (or you) can think of, but it’s crucial to do it this way, and to get it right. While standing, set your feet apart about the same width they would be on the bike (about 8″). Straddle a level, applying the same amount of pressure as your saddle would when sitting on your bike.
Have your buddy take the measurement from the ground to the top of the level. It’s important to keep the level straight, and the tape measure as perpendicular as possible. This is easier than it sounds, so if nothing else, make sure the level is spot on.
Stand straight up, preferably against a wall, with your feet about 8″ apart again.
Have your buddy measure from the floor to your jugular notch. This is the point where your collarbones meet in the center. It’s also referred to as your sternal notch.
While still standing straight up with your feet apart, have your buddy place the end of the level at the top of your head, and while holding the level straight, measure from the floor up to the bottom of the level. Again, it’s important to keep the level straight, and the tape measure as perpendicular as possible. This is easier than it sounds, so if nothing else, make sure the level is spot on.
