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.

Deep paint scratch or frame crack?

Lastest post 1 month ago

Hi, everyone! I'd like to ask you about your opinion on whether or not this is just a deep scratch (scuff?) on the paint or a crack on the frame of my aluminium road bike (please see photos below). For context, the area shown on the photos would be the seat tube, right about where it is joined by the seat stays. I already did the "coin soundcheck" test to help me diagnose the problem but I'm still...

Gravity Bike Crank

Disk Brake Spacers

Lastest post 2 months ago

Good morning! I purchased a new mountain bike a few weeks ago and picked up a frame adapter so I could put it on my trunk rack. The problem is that the front wheel is really low. A hitch mount is in the future but for now I figured I would just remove the wheel. My question is whether I should pick up a disk spacer or could I just use a chunk of cardboard? Not traveling all that far but don't wan...

I've tried searching for YouTube assistance but to no avail. Cycled to the shops this morning and the gears weren't functioning, had a look and something has gone horribly wrong.

Weird brake hose

Lastest post 2 months ago

Hi I bought these SRAM force 1 brakes and they seem to be really unusual. Has anybody ever seen a hose like this? I need to shorten it to run it through the frame but I'm baffled by these hose ends. These were sold as "pre-bled", which I didn't notice until I had them. How can I shorten these hose ends?   IMG-2735.jpg (Size: 54.74 KB / Downloads: 41)   IMG-2736.jpg (Si...
