Well the new stem hasn't arrived yet, but here's a picture update showing leg extension after the saddle/seatpost adjustment. Feels quite better. Holding my upper back a lot straighter now, and the elbows are more relaxed. I tried taking the seatpost even a bit higher after I took the picture, but then I felt like I crossed the threshold of comfort. Took it back to where it is in the pic.



And here's the horizontal position again

Glad you feel good! The first picture you foot in not parallel to the ground. If it was, I would say you are the the max height for extension. Once you get the new stem, mark you current position and fiddle around a bit.

I would say your KOPS is still ab bit forward. Get a seatpost with some more set-back and you will be happier in the long run. Or try a Fizik saddle with longer rails for more adjustment.

Again, fit is very subjective and fiddling with it can sometimes yield great or worse results.

Good luck!

+1
On the 2nd pic I feel like ur knee is still much in front of the center of the pedal. Is the saddle currently as far as it could go on ur seatpost?

Wow. What a completely ignorant statement. I'd wager I've been riding bikes since before you were an itch in daddy's pants.

If you have had any experience with fitting you'd know that the cockpit length is the primary driver for a proper fit. That doesn't mean other factors aren't in play.

Yes, on most track frame with really short TT you would know that it most likey a very short cockpit length. Unless is a 48cm frame with a 5'2' rider.

How many 56cm + plus frame have you seen here with 60-70mm stems? Think those4 are fit right? 53cm and a avg rider and a 70mm stem give the right fit? Most likely not.

I have been riding for a long time myself.

Yes you are right: "If you have had any experience with fitting you'd know that the cockpit length is the primary driver for a proper fit. That doesn't mean other factors aren't in play."

Now how many are fit right overall here?

Oh ok, let me ask you a very straightforward question.
Why would you post information that won't in any way answer the OP's question or help his situation? He clearly asked for help on fit, so you go and post something that is, like you said, IRRELEVANT to his situation?
Very helpful.

No I did not know everything about bikes. But I do clearly know more than you.
What more do you know exactly? So far no one else here has disproved my suggestions to the OP, and in fact, have supported it or says it has helped.
I can't say the same about your "advice" (aside from others not accepting it).
Sorry to burst your bubble.
Maybe you should go back to your little imaginationland where you know so GD much.

I don't need that video and form that photo you cannot his seat was too low. That's you uneducated guess.
Again to solidify my speculation and prediction from appearance , I ADDITIONALLY posted a video for him to confirm a correct fit.
I never suggested he solely follow my assumption.
If you say that's uneducated, that's your opinion, but if I predict that it is too bent, that's my opinion.
We can argue here all day but there is no wrong/right OPINION.

(and for the record, my speculation was in fact correct)

I never rejected you suggestions.I just rejected on how hight that the OP should possibly raise his post. You advice was basic. But you argued about SO and overall hit where you are full of useless info.
And where did I indicate a specific enough of a measurement for you to judge that it's "too high". How can you judge the "extent" without a specific value?

I try to help with what I know on this FG/SS board. In my observance, lots of newbies are here that never owned a properly fitting bike or only have any real knowledge of bikes in general.
Am I not doing the same?
You disagree with my speculation and opinion from the pic that his saddle height is too low. Now you say you don't reject it, but don't agree to the "extent" I have taken it.
I said:
1. Raising your saddle height.
(With the crankarm at 6 o' clock, your leg should be nearly straight, there should be a very slight bend.)
And you are to judge that because "slight bend" automatically means its not within the 15-25 degree range?
The video I provided explicitly states a 10-20 degree range. Yet you didn't "need" to watch it to jump to insult our members here, imply your unlimited knowledge on bikes, and accuse me of giving "false" information.
Maybe you need to rethink your perspective on yourself and other people, and lose the narcissism as well as the "I'm better than everyone" attitude.

Here's a picture I took 2 years ago. Close enough?

woot. The new 100 mm stem arrived today. Doesn't look as purty as the short stem, but huge difference in riding position. Felt slightly awkward at first, but definitely much more open.



BTW it's colder than a mother****er. Was riding the bike to and from the LBS to get the stem properly installed and get new cabling for the brake, and was numb all the way. Not a fun ride.

I think it looks better than that short, negative rise stem you had on there before.

From your latest pictures, I think you should bend your elbows more and support yourself more with your core. Looks better, but still not quite there. Ideally, you should be able to lift your hands off the bars while riding and maintain nearly the same position with just your core for support. Might take some conditioning, but that's what you should aim for.

I was thinking about this when I installed the longer stem the other day. As i mentioned, the bike feels heaps better comfort-wise, but felt a bit unstable in terms of control. So, placing the stem lower on the steer tube would give me more stability? I'm guessing doing something like this would affect comfort negatively again... yes/no?

your stem will be plenty stable as long as you have the right amount spacers on and the steerer and it's clamped down tight. it's most important that you have an angle that feels comfortable, and if that means you've got spacers, so what? They make them for a reason, of which having an unstable cockpit is not one of.
