I love that you mentioned the seatpost slipping and that it's your responsibility as a rider to know your measurements/setup.  Take notes/photos and check every so often, especially if you notice things feeling off, or if you suddenly have pain.  I can't tell you how many times I've done a bike-fit for someone, they complain of issues a month/2 later and when I see them again, the bike comes in the door in a wildly different position than it left the last time I saw it.  Especially with any clamps and carbon parts.  Anyone whose bike has even just fallen over can tell you that's enough force to twist/move brake levers and these are torqued the same/more than most seat post collars.  Even with Carbon paste, things still slip.  I see a lot of people putting tape on their seatpost to mark the position, but they put it against the seatpost collar, so if/when it slips, its just going to slide the tape up and you won't notice it.  For this reason, I leave a 1cm gap between the tape and the collar.  This gives a little room if you ever need to come down 2-5mm, which I do sometimes if I'm riding rougher terrain to give me a little room to lift/cushion vibrations into my butt with my legs.  Also, if the post slips at all, you have a visual cue it's happening.  Also, this still let's you put the saddle back exactly where it was = measure a 1cm gap between the bottom of the tape and the collar.

There's been lots of different methods floating about for years,a common few were when your sat on the bike with your heel over the pedal axel your leg should be straight so that when sat on it with the ball of your foot over the axel it should be slightly bent, there are others but as commented they're designed to get you in the ball park and you tweak from there 😊

Phil's a great guy, sparing his time to deliver free tips & advice. Newcomers & those contemplating "jumping" on 2 wheels may also well appreciate a update brief on saddle types. Pro's & con's, if any, of different types, widths, groove or no groove etc.
Newbies in the bike store facing a myriad of choice  🤔

Method 2 0.883 was an absolute revelation for me… my saddle has come down 4 cms… I know I’m older now and have probably shrunk a bit but thinking back I can’t recall where my old position came from probably heel on pedal. Phil is so right about the window of flexibility in riders. My new position is far better I have reduced saddle pain, have better cadence and less numbness in the hands. Thanks for posting up the video

Would like a chat about the effect of changing crank length and pedal cleat/shoe stack height on saddle height.

That bony outer flare of your hip is the iliac crest btw, the greater trochanter is the corner of your femur as it bends inwards to the hip joint.

I love Phil Burt because he don’t gives someone the feeling he would be totally wrong

I used the 1.09 method and it worked. Rode for years. I did notice that I would rather have my foot a little more horizontal at the bottom of the down stroke, so I lowered my seat about 3mm, and now I seem to get a little more power.

I ran across the seat height to hip bone theory on a PT site. My seat was at a comfortable height and I checked this method by standing next to my bike. I was amazed how it seemed to be spot on! Katie could you possibly ask Phil to explain the cleat position to saddle height ratio the next time you do  a video with him.  Great stuff  you provide on your channel! Much gratitude.

Great video!! Would love a video showing saddle fore aft especially how much fore and high up a cyclist fit should be and why it helps to engage glutes more?

Just took delivery of a Bowflex C6 spin bike and this is exactly what I needed to know. Thank you

Again another easy to grasp master class from Phil...cycling can be intimidating to those of us who are afraid of touching anything on the bike lest we screw it up. Thanks, Katie and Phil!

Great timing. New saddle came in to work office this morning(SMP Well). Closed the door and started fiddling away with old saddle and new to mark as close as I can. Wish I could record trying to hold myself steady on desk saying "yup that feels good" 😂.

Great point about eveyone having a "window"; I found it with my old saddle through trial & error. I could ride for long miles and feel great.  Here's hoping the SMP is in same range to start.  I've always wanted a fitting but money is an issue, being curious isn't so it goes a long way for one to "learn" their bike components and not be afraid to tinker around.

I can't thank you both enough for this video btw, I was on the cusp of jacking cycling in, I'd spent 6 months messing about with fore/aft/saddle height & tilt and nothing I did seemed to do the trick.  I decided to buy a body tape measure and actually do it properly using the Lemond method you mentioned and boom, it was perfect!  Using the zwift ride measurements, I had the saddle about about 2 inches too high!  Turns out I have a small inseam for a 6ft 3 guy and it was turning every ride into an unstable pain fest.  Once again, thank you both.  If you're struggling with the same issues, honestly just try it!  See you in Watopia!

I sat too high for over 15 years. I've now moved the cleats almost all the way back and lowered the saddle by 2 cm compared to before. Additionally, I dropped the cockpit. I adjusted everything until my pelvis was truly stable. Due to years of compensating for the overly high saddle, I developed massive problems, and cycling stopped being enjoyable for me.

Great video!!! I needed this information!! Thank you for posting!!

I just used to guess my saddle height but it was always so I could only touch the floor with my toe on one foot. I heard about the 109% method which is where you multiply your inseam by 1.09. This is measured from the top of the saddle to the top of the pedal so it takes into account the length of the pedal arm. My saddle was very close to that result already so I trust that method. So when I get a new bike I just set it to that number and it saves a lot of hassle getting the seat right.

Good clear advice.

Great info thanks Katie

Many thanks for the video. Very helpful!
