Just to confirm that I'm not THAT crazy, I did a quick search and found quite a few photos of similar forum member's bikes. I'm not alone!

Sorry I missed this. Yes, my dislike for the bike had nothing to do with fit. All I can say is it was not a pleasure to ride, as my vintage road bikes are. I never got down to analyzing why.

This is where I am at. I'm baffled at the concept of a bike giving one standover issues, but has half a foot or more of seatpost sticking up. I don't get it.

Answering the Question

To be right for me, my bikes require the low standover height of a 19-20" frame, but a higher seat, and consequently higher handlebars. Finding the right frame size has not been difficult, but I do need to switch out the stem for a longer one. Is this unusual, or fairly common?
I estimated some measurements from the photo: Saddle to crank spindle: 68 cm Saddle to pedal in down position: 85 cm Top tube stand over height: 72.5 cm Saddle to handlebar center: 51 cm Saddle to bar vertical drop: 0 Comparing several other cyclists with 68 cm saddle-to-crank, I estimate that [MENTION=248524]Kross[/MENTION] is around 5'6" in height. I see two questions: 1. [MENTION=248524]Kross[/MENTION] claims to prefer a low standover height, but a high saddle position. The photo supplied indicates that this is the case. Since the estimated saddle-to-pedal distance is ~12 cm more than the stand over height, that's a very large stand over clearance. But is it "unusual"? I certainly wouldn't fit anyone on a traditional diamond frame with that much clearance. 2. [MENTION=248524]Kross[/MENTION] claims to need a long stem to obtain the estimated 51 cm saddle to bars distance. To find out if 51 cm is unusual, let's look at other cyclists preferring the same saddle-to-crank measurement of 68 cm: https://cimg5.ibsrv.net/gimg/bikefor...4957e3c033.png With a 51 cm saddle-to-bars and a 68 cm saddle-to-crank spindle, [MENTION=248524]Kross[/MENTION] is indeed an outlier, with only 3 of the 75 cyclists preferring that distance or longer. |

Yep, other people also have badly fitted bikes. No surprises at all.

I never claimed I needed a longer stem, as in a long REACH stem. I needed a taller stem to get the bars to seat height. I moved the saddle back after this photo was taken. So any measurements made from this photo on saddle-to-bar distance are also wrong. I guess I now fall further from the norm. I'm OK with that. Normal is overrated. When I get a chance I can get you the actual measurements. |

There's the confusion. Long describes horizontal distance, tall describes vertical distance. No matter. Bar drop preference runs the gamut, but regardless of how high or low you want your bars, your saddle-to-bars distance is still quite long for your saddle-to-crank length.

I saw your comment and adjusted the dimensions as if the saddle had been moved to center on the rails. Even adjusted, your saddle-to-bars distance is a high outlier. That would be great. Please include the following: Saddle top to ground, vertical Handlebar top to ground, vertical Saddle top to crank spindle center Saddle nose to handlebar top center I do need to be careful about "tall" versus "long". |

And, unless you measured me, how would you know what my dimensions are and if they are unusual? Come on, don't get goofy! |

Not directly, but definitely you are getting answers suggesting that you are not the norm. But it is hard to say whether anyone is "built like this" when all you have posted that would allow anyone to successfully answer that is a picture of what seems to be a very poorly setup bicycle. If you really want an answer you should provide a pic of you, maybe a pic of you riding the above-mentioned bike, and probably some dimensions (height, inseam, thigh length, lower leg length, torso length, arm length, forearm length, upper arm length). |

"No, I haven't seen one done that way before." "I have seen that before, but not often." "I have seen lots of bikes fitted out like that." Again, it ain't rocket science. |

And I'm not about to open yet another can of worms by posting my photos and dimensions. I am almost certain to be "poorly setup". Because I'm positive there is an arm length and hair color that is or isn't acceptable. Please let it go. |

Again, it ain't rocket science. Here is my answer. Yes, I have seen lots of people who have badly setup and don't recognise (or don't want to recognise) that their setup is poor. Again, I cannot answer your original question (and nobody else can either), because you have provided no information whatsoever about how you are built. At the moment (for lack of any information that tells m otherwise) I am picturing someone with incredibly long legs, incredibly short arms, who is massively overweight and has no flexibility. Given that, my answer is no, I am not built like that, and I don't know anyone who is. |

It's sad that the idea of what is or isn't a "poorly setup bicycle" is so tightly regimented. Are all bike fit enthusiasts prone to OCD?

Anthropometric studies of the human body have been done many times. For a normal person at a specific height, leg length, arm length, hand size, and torso length all fall within a narrow range. Certainly a narrow enough range to fit on a bicycle specified by rider height. Also, I've personally gathered bike fit information and fitted thousands of people on bicycles. You're not special or unusual (at least your physical dimensions aren't). |

The OP's bike fit looks pretty typical for a recreational or endurance cyclist. Handlebars are just slightly higher than the saddle. That's why sloping top tubes are used on nearly every bike produced today.
