important: Nuts and bolts on your bike should always be tightened to the manufacturer's specifications.

How to Adjust Your Seat Height and Angle

Correct saddle adjustment is important to prevent knee injury and increase efficiency.

Video updates

  • 00:12 - Seatposts will have a "minimum insertion" marking. The seatpost must not be raised beyond this mark.

Proper adjustment of your seat height, angle and position is important in order to avoid injury and improve your cycling efficiency.

Seat Height

Adjust your seat height by loosening the pinch bolt where the seatpost slides into the frame. Twist the seat to raise or lower the post as needed and then tighten the bolt.

Now get on your bike and place the ball of your foot directly on top of the pedal spindle, when the crank is at the bottom of the rotation. Your leg should be just slightly bent. If your leg is too bent you will need to raise the seatpost, and if your leg is too straight you should lower the post. Another way to check this is place the heel of your foot over the pedal spindle. Your leg should be exactly straight in this position.

Seat Angle

Seat angle and position are adjusted by loosening the seat clamp under the seat. These often have a lot of parts so be sure to only loosen the clamp enough to move the seat around.

Your seat angle should be horizontal, but you may want to play with the adjustment. Women often like to have the nose pointing just slightly downward, while men often feel more comfortable with the nose pointing slightly up.

Front-to-Back Adjustment

You’ll notice that the seat has two rails that the clamp tightens on to. This allows the seat to slide forward and backward, which adjusts your body’s distance in relation to the bottom bracket. For proper positioning, place the ball of your foot on the pedal spindle with the crank arm pointing directly forward. If your seat is in the correct position your knee should be directly above your pedal spindle.

Now tighten your seat bolts and go for a test ride. You may have to play with these adjustments several times until you find the seat position that is most comfortable.

Make a freewheel removal tool

Latest post 7 hours ago

Make your own strong, inexpensive, freewheel removal tool, using a car wheel nut. The most common bikes with gears, use freewheels. There are other gear systems for bikes, but they are used on less bikes. The tool I will describe is for the most common type of freewheel, as shown in the picture. There are freewheels which require different tools, particularly on older bikes.   free...

On one bike I have either the bottom of the range Shimano rear derailleur, or an imitation copy of the bottom of the range Shimano rear derailleur. The spring tension is weaker than many other rear derailleurs. The chain sags more than it should. With a derailleur like this, the chain rides up on the sprockets more than it does with a derailleur with stronger spring tension. This results in the s...

Derailleur causing issues

Hello there, I had managed to replace my inner tube and outer tyre successfully, however since then I have been trying to re-fit my rear tyre back onto the frame to no avail. Initially I thought the axel was at an angle. I have undone the nuts and bolts many times, rode the bike, then either the tyre starts rubbing with the frame, or the pedals become really stiff to rotate. But today I have r...

I have these Chinese freewheels. On the inside are ridges which are supposed to be there so you can use the tool to remove it. With these freewheels, the ridges are very low. I have a tool, also made in China, and the ridges on the tool are also very low. So when trying to use the tool to remove the freewheel, it does not grip properly, and it can't be used to remove the freewheel. The metal on ...

My bikes' front and rear tires are not aligned. By this I mean a straightedge held against the front or rear wheel will show an appromixately 2 inch offset as compared to the other wheel. The dealer says this is "within specification". This is the second bike with the identical situation. So the wheels are in a different track. If this were a car they would call this dogtracking or crabbing. ...

The most common bikes with gears use a freewheel hub. Some bikes with gears have other types of hubs. Axles may bend and break in freewheel hubs. Heavy riders are more likely to bend and break axles than light riders. People riding on rough tracks are more likely to bend and break axles than people riding on smooth roads. Axles are more likely to bend and break in hard tails, than bikes with r...
