Fit a Bike - Is This the Right Size for Me?

Hi Thrr!!!

I am writing sharing this information so that it might help someone who wants a bike but do not know what to buy and which size is right for them. When I see lot of enthu. riders ridding on the roads with either wrong frame size/ seat height/ handle adjustment. I did some research so that this might benefit someone and save them from some injury... Its important that few of the above mentioned things are done RIGHT.

Is This the Right Size for Me?

For most riders, the first step in getting the right size bike is to stand over the frame with both feet flat on the ground. A properly-sized road bike frame will give an inch or two clearance between the top tube of the frame and your crotch. Not too much, not too little. A mountain bike should have more space - maybe the width of your hand across your fingers.

On women's bikes that don't have the high top tube going between the seat and the handlebars, you can skip this step.

Adjust the Bike Seat to the Proper Height

You want to have the bicycle seat set to a height that allows your leg to extend until it is almost completely straight when you are sitting on the seat. There should be only a slight bend to the knee when your foot is on the pedal in the bottom position. This will maximize power and minimize fatigue.

A common mistake is for people to think that they should be able to sit on their seat and still plant their feet firmly on the ground. Riders should come off their saddles and straddle the bar when stopping the bike. If you can sit on the seat and touch your feet to the ground other than on tippy-toes, your seat is too low.

Adjust the Level of the Bike Seat

For maximum comfort and pedaling efficiency, you want your seat to be pretty much level, so that you can sit on it and pedal without having to consciously monitor where you are on the seat. Too much forward tilt, and you'll feel like you're sliding forward. Too much backward angle, and you won't be able to get any power and you'll have the sensation that you're slipping off the back. Both of these situations are distracting and uncomfortable.

When on a bike seat, your weight should be borne by the same spots on your rear that you feel underneath you when you sit upright on a hard firm surface. In addition to adjusting the tilt angle, you can also move the seat forward and backward in relation to the seat post. This will help make sure you're comfortably centering your weight in the right places.

 

Proper Handlebar Adjustment

The goal of handlebar height adjustment is to find the position where you can ride comfortably without putting strain on your back, shoulders or wrists. There is a lot of personal preference here, and a fair amount of variation between body types, so don't be afraid to experiment until you find the setting that is best for you.

Generally, the following guides may be used for different types of bikes:

Road bike: on a road bike, the top of the bike's handlebars should be a bit lower than the top of the saddle, in the range of an inch or two. This allows for a definite forwarding-leaning, more aerodynamic ride.

 

Setting Handlebar Height - Do What Feels Right

Remember, when setting the height of your handlebars, personal preference and variations in physique will have an important effect. You should feel free to make adjustments until you find the position that allows you to ride comfortably for extended periods of time. In general, the higher the handlebar is set, the more upright you will sit.

NOTE: All handlebars have a minimum insertion mark. Make sure you don't raise your handlebars into a fixed position so high that you pull this mark up out of the frame. Below this point, it means that there is less than two inches of the handlebar stem remaining inside the frame, and the handlebars are susceptible to breaking which will cause a mean crash.

 

Hope this helps!!!

Have a Happy  & a Safe ride...
