18. How to Adjust Your Seat Height and Angle
Correct saddle adjustment is important to prevent knee injury and increase efficiency.
Proper adjustment of your seat height, angle and position is important in order to avoid injury and improve your cycling efficiency.
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 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.
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.
So I discovered the saddle on my mountain bike felt funny and discovered when I got home that the spring suspension had snapped and I was missing a piece of bar. I wonder is this normal after 5000 miles of bumpy roads and trail riding, i.e. due to metal fatigue, or could there have been a flaw in the steel? The bars were about 8mm thick. Anyway after grinding the ends of the break down and re-welding with stainless steel rods, the joint has stayed intact after a further 2000 bumpy miles. I could have bought a new saddle but it was a challenge to repair the old one!

My question will probably sound crazy, just bear with me. I have issues getting on and off the bike, a long story why, it seems to be my permanent reality. I like the seat way up so that I may maximize my leg stretch. I get on my bike and raise the seat several times but then must lay the bike down or lower the seat to get off. Hindsight is always 20-20, perhaps I should've bought a step thru frame but when buying, I wanted fat tires, disc brakes and a suspension fork and those were features were not on step thru frames at the LBS, and the LBS already thought I was crazy from my never ending q...

Question about compatibility with a Chromoly Redline laid back seatpost, to be used with a T800 (T1000 reinforced) carbon fiber frame:
My potential concerns are:
1) Will the laid back style be too much stress for the carbon fiber frame?
2) The frame uses a 31.6mm seatpost, and the Redline is 25.4. I have a Shim to convert. From a strength standpoint, is the shim an issue?
Basically, I do not want to... Read more >>
I have a Panther III and the saddle pan is cracked. Do I buy a newly manufactured saddle or buy the vintage saddle on ebay that is a match? My worry is that if I buy the vintage seat the pan will crack sooner rather than later.
Any comments are appreciated.
Hopefully this link will get you to the photos of both bicycles I am cleaning up. https://www.flickr.com/photos/121016477@N03/... Read more >>
The seat that came with my Peugeot is un-comfortable.
I came across a seat this spring at ALDI (Yes, the food store!).
.. for $9.99
It's a Selle Royal seat, and has "Made in Italy" molded into seat bottom, but a sticker written in what I think is German, so I don't know the model number.
I did have to bend the attachment part somewhat for the larger French tubing....
BUT.... It's very Comfortable!
I did a search on Google for Selle Royal bicycle seats, but didn't find this exact model... But it is closest to the ... Read more >>

After several years in storage, my Counterpoint Presto short wheel base recumbent appears ready to ride, with one exception. The elastomer donut that served as seat suspension had melted! Never saw anything like it. Took me an hour to clean off the melted debris from the chain, fender, and brake mechanisms. Anyone know where I can buy this sort of thing? I've been out of riding for about 15 years and simply out of touch. Any help would be welcome. Thanks. Jules... Read more >>

My hubby and I just upgraded our bikes from Roadmaster Fury's to Raleigh Venture 3.0's. He's having a problem though: the native seat on the Venture is irritating his hemorrhoids and we are wondering what sort of seat to replace it with?

The bottom part of the clamp that secures my saddle broke. I have some pictures:
You can see how the bottom clamp is broke and bent. I think someone was trying to steal the seat. Where can I order this part online?
and here is the bike, trek 730
The saddle is from a Canadia firm called spider, it's noseless. Thanks in advance.

I've got two identical road bikes, set-up the same way, with all the same components and everything, except the saddles are different. One is on my go fast bike and it is 160mm wide and the other is 145mm wide. The 145mm saddle bike I use more for touring and have a front bar bag and rear bag with rack. Both of the saddles are the same length, just that one is a little narrower than the other.
My question is:
The measurement on both bikes from the back of the quill to the front end of the seat is the same, but the one with the narrower saddle seems stretched a litt... Read more >>
Hi, I ride with my seat as far back as possible - jammed against end of rails. My present seatpost has a 1" setback and to get my weight more balanced I need at least 1 1/2" to 2". I would appreciate any suggestions regarding possible brands. I am now through with racing so I like to keep my purchases to the lowest possible price, don't care if it's made in Taiwan !!!! I'm cheap too.... Read more >>
Quick question as I've never had this problem before. When I tighten the clamp enough to keep the seat post in place the clamp pops up off the frame, releasing the seat post - not ideal you might agree.
Bike is brand new so stock size post/clamp. Clamp isn't quick release, seat post is an Ritchey alu one and frame is carbon.
I'm thinking its probably the clamp that's the weak link here? I know you can get different clamps depending on whether seat post is alu or carbon - but does a carbon bike frame add further restrictions?

Hi If anyone can help me with this problem that would be great.
On my Mountain bike, the Seat Post Clamp or Seat Clamp that adjusts and holds your Seat Post in place has broken. I have a non quick release clamp and the screw that you tighten to adjust the height of the seat post has worn in the inside of it.
Basically My Problem is that I don't know what I should do to get the clamp off the bike as I am happy to buy a new one but I don't know of the method I should use to take off the Seat Clamp.
I tried Drilling the screw with different sized drill bits ... Read more >>
I am almost done restoring a cherry 1987 Miyata Trail Runner to be a short haul urban errand runner, brief stops at the store/pharmacy. But I worry about the quick release seat post clamp and the Brooks Gel Lite saddle as being easy marks for a thief. I can lock down the rest of the bike using u-locks, but the rest baffles me in terms of effectiveness, cost and usability. And I don't want to ugly the bike. I've thought about a bike chain inside rubber tubing, wrapping and padlocked somehow, but it's not clear to me that would work.
Any engineers, etc., out there?
