Method #1: Measuring Inseam Length to Determine Saddle Height

You may simply perform this inseam measurement in the convenience of your own home. The ‘LeMond approach’ is one form of this method (1, 2). Your inseam length is multiplied by 0.883 in this approach.

KernowPhysio’s Scott Tomkinson utilizes a version that we prefer. This person is in charge of providing WorldTour teams with advice on various aspects of bike fit. Here’s how it’s done:

Stand with your feet about the width of your shoulders apart while removing your shoes. To clarify, I’m saying that you should extend your knees. One’s shoulder-to-toe distance is equal to the distance from one’s feet to theirs. Open your feet wide enough to leave a spacing of 50 centimeters between them, if that’s the distance from one shoulder to the other. It’s done.
When you’re sitting on a saddle, apply pressure to a ruler or spirit level positioned between your legs.
Make a note on the wall at the height of the spirit level. If this is done in the living room, a pencil could be utilised.
A measuring tape is then used to record the distance down to the ground. Not to be followed is the leg’s line.
Remove 10 centimeters from the measurement. To calculate the beginning height of your saddle, subtract 10 cm from the size of your inseam leg.

Has your saddle measured from the floor to 66.9 cm in height?

You can use this measurement on any bike now that you have it. The measurement should be taken from the centre of your bottom bracket to the very top of your saddle, following the line of your seat tube.
KernowPhysio’s method will assist you in achieving a close approximation of your ideal saddle height. If you want to get the most out of your saddle, you may wish to adjust the height of the saddle. This is another subject of debate among riders. There are several variables, as Tomkinson points out: “Similar to any other way, there are going to cause the height of your saddle to require a little bit of tuning.”.

If a rider has a leg length difference or a lack of flexibility, or if their posture is scoliosis or pelvic instability, these could all affect their ability to ride a motorcycle safely.’ So, employ KernowPhysio’s Scott Tomkinson approach to come as near as possible to your ideal fielding position. ‘ Then, fine-tune this a bit to get the most out of it. You’ve completed your task.

A Mountain Bike Handlebar Rise Up Method #2: The Heel On Pedal Method RELATED POST

Alternatively, you can use this method. It’s easy to understand and has lasted for a long time. It goes like this:

Sit on the bike or lean against a wall while it’s connected to a turbo trainer. To make sure the bike is straight.
Put one of your heels on a pedal so that it is around six o’clock in the clockwise direction. Basically, one pedal is at the bottom and the other is at the top of the pedal board..
You should have your foot in this posture with your leg totally straight.
If you see a bend in your knee, you may need to raise the saddle farther.
When you place your heel on the pedal and notice any movement in your hips, it’s time to remove the seat.
To double-check, place your foot on the pedal that was previously up and the pedal that was previously down. And repeat the inspections, too. If you have a problem with your hip, you may notice that one leg is shorter or longer than the other. Insoles are a possibility.

At around a 25-degree bend, your knees should be. Similar to standing in an athletic position, this position has a calming effect on the body.
In the absence of a measuring tape, you can use this as a reference to manually adjust the seat height.

2. Determine the length of your inseam.

Measured from the inside of the leg, this is your crotch-to-ground distance. Hold a hardback book’s spine under your crotch while mimicking a seat’s feeling to get an accurate inseam reading.
Take a few steps back with your feet 6 inches apart, and then stand up.
The spine of the book should be measured all the way down to the ground. Your (inseam) is
1.09 times the length of your inside leg. The result is the recommended distance in inches between the top of your saddle and the axle of your pedals.

Get comfortable with adjusting the seat post.

Adjustment is accomplished at the junction of the seat post and the bike’s frame for each seat post. At the base of the seat post, there is a quick-release lever that can be pried out with one hand and adjusted. The seat post has been bolted if a tiny bracket with a screw is visible.

Adjusting the seat’s height to match your height is the fourth step.

You may adjust the height of the seat post by simply sliding it up or down. If the seat slips and you need to have it fixed again, nicking the post can be useful.

Make sure the seat is securely fastened. 5.

Using an Allen key or an adjustable wrench, retighten the bolts until there is no more movement. Alternately, press the quick-release level down to its locked position. You don’t need to make it so tight that you can’t undo it later if you need to.

You can double-check your results by going for a test ride.

You can take the car out for a little spin on the driveway for some practise. Make sure you can easily reach the pedals and climb on top of the bike without locking your knees. As you pedal, get out of the saddle as comfortably as possible by standing up. Ascertain that the seat is positioned so that it faces directly forward. If you don’t do this, your riding position will become awkward and uncomfortable.

As you cycle, keep your heel on the pedal. A slight bend in your knee with the pedal at its lowest position should be observed when doing this action. This is now the ideal height for your chair. “

Use cages or clip pedals on your test ride if you have them. They will have an impact on your journey.
Every person is born with a unique physical type. Your inseam measurement serves as a good beginning point. The bike should then be adjusted to fit you comfortably.
Do you have any concerns? To solve a problem, adjust the seat up or down a tad. If you have knee pain, the most common culprit is likely to be your chair’s height.
The problem is that the seat is too high if the pain is located on the back of the knee.
The problem is that the seat is excessively low, which causes soreness in the front of the knee.
As you pedal, your hips should not sway back and forth. If your pedal strokes cause them to shimmy to the side, you’re sitting too high in your seat.

The forward position and angle of a bike have an impact on your riding comfort.
To determine the ideal saddle fore and aft location,

Make sure one foot is in the 3 O’clock position as you pedal.

Imagine a straight line extending from the front of your knee all the way to the ground.
The pedal’s centerline should be intersected by the line. As a result, in the 3 o’clock position, the knee should be just above the pedal.
To move the seat forward or backward, loosen the bolt located under the seat.
A small bolt is located at the back of the seat, pointing downward toward the rear wheel. There is a little bolt that is used to adjust the position of the passenger seat.

It connects to a bracket in this manner. The seat is secured in place by the bracket clamping onto little metal tubes. Turn the bolt counterclockwise to release the clamps holding the seat in place and lessen the strain on them.

Make sure the seat is far enough forward so that you may enjoy a comfortable trip.

If you are having any of the following issues, the seat should be shifted forward or backward because the bolt is free.

As you stand, your fingers begin to numb as you try to reach for the bars, which could indicate that the seat is too far back.
Comfortable riding down a slope with soreness in the shoulders is a struggle. This could signify that the seat is pushed all the way forward.
Make sure that the angle of your seat is the same as the angle of the floor.
A small adjustment to the seat can alleviate any discomfort, especially in the crotch area. However, no more than a 3-degree swing should be allowed.

Women’s seats should be tipped down slightly for maximum comfort.
The seat should be tilted slightly upwards for men’s comfort.
On the seat’s side, loosen the bolts to modify the seat’s angle.
The bolt is most typically found on the right side of the seat, but this is not always the case. It allows you to quickly and easily adjust the seat’s inclination and then re-tighten it. Seats that are a few years old may have two little bolts located below the seat. One is at the front of the seat post, while the other is positioned behind the Seatpost. To adjust the seat’s angle, these are important components.

To raise one side, tighten one side while loosening the other, somewhat like a seesaw.

You should never make significant changes to the seat’s angle. The seat’s height and forward position should be examined before adjusting the angle, if necessary.
