also, to run a 58cm top tube at a 75mm saddle height, with a 130mm stem you either ride no setback, no drop or have the proportions of an ogre. seeing as 74cm is nominally seen as a 54cm bike, you probably just run your seat way too low.[/quote]
for me it’s 57.5tt, 110 stem, 8cm dorp but the saddle height and setback are the same. Don’t claim you’re some master of bike fit then go on to say stupid shit and demonstrate your lack of reding comprehension like this btw and ETT is fucking relevant jesus christ[/quote]
so you are quantifying that with posting sagans bike, who rides by far the most stretched out position at his height, he also is 6 feet tall, where most people normally proportioned at that height fall into 76.5-78cm height ime. closest I’ve seen to that disparity is a coworker who rode 77cm saddle height and 61cm of reach, and he looked like fucking superman on the bike, but it worked for him.
and yes, effective top tube is useless. It is not an independent variable and can change wildly with sta and hta.[/quote]
I agree that my saddle height is a bit lower than most for my height (6’) but the setback partially makes up for it. I only brought up sagan because I wish cannondale offered his frame size, although I get by with minimal drop because I bend my elbows a good amount. My reach is 59cm and I also have a 56cm road bike with a 130mm stem, I don’t think any of this is particularly unusual, it’s just that these days it’s more stylish to have less horizontal reach and more drop I guess. Granted my fit/style is pretty old school.
Also if you’re saying the ett changes with the angles of the frame then why is that measurement useless if it’s taking these factors into account? lol…[/quote]
also, keep in mind sagan rides hte frame he does because hte mold was made for a much larger dude, and he prefers a longer front center coming from a mtb background. You would be fine riding your contact points (assuming your saddle isnt super jacked) on a 54cm frame, 130mm stem and a drop more fitting of the reach you like. Should you be more nominally on a 77cm saddle height, or even 78cm (you see a lot of whack shit) a 56cm would be great, but you will be fighting the good fight against the ever raising headtubes. Once again all of this is bogus because everyone’s proportions are the same.[/quote]
Yeah, I’m sure I could get away with riding a 54, maybe I’ll try one out sometime and see how it feels. I can also ride with my saddle 1-2cm higher if I want to but it is less comfortable and there is no increase in power output. I’m planning on sticking to 56cm frames from now on but I think the 58cm frames I have feel as good, but different, I really like the extra room for climbing and sprinting out of the saddle, but I think the 56 has slightly better weight distribution.
