I get poked fun by my teammates for being a human pretzel. It's comfortable for me. I get what you're saying, xena.

At the same time, it's pretty great going for a ride with my dad, whom, no matter how we slice and dice it (and he's doing great for 58), there is no way he's going to be slammed/low/what have you. I've tried. His hips won't do it (and that's with an Adamo saddle).

Why is this such a trend?


It makes far more sense to look at whether riders' positions on said bikes works for them or not.

If you can't find a stock bike that fits you without a crazy stem/spacer setup you aren't looking very hard.

Looking at other riders on the road, many riders typically have their saddles way behind the BB centerline. That puts their junk in the way of riding with low enough handlebars, so manufacturers started making saddles with cutouts, and when that didn't work, frame designers started to increase head tube lengths to save on spacers. When that wasn't good for riders who wanted enough reach but less stack, stem manufacturers started to make a greater variety of -17º stems. :roll:

Ok, I'm just mocking here but my guess is that the actual justification probably lies somewhere in the realm of design decisions... To be honest, I don't like nor fit a frame with a head tube that's too tall, so I end up riding a smaller size frame with an unusually long stem (to compensate for something, of course). Naturally, stem is slammed. Hello ape factor +10! :mrgreen:

I just wanted to add. These bikes with taller head tubes should have longer and slammed stems, so that's why compact bars were invented! :smartass:

I am not sure if it's a trend all through! I mean there are several brands running very low and long frames (stack and reach).
Several i looked at which i had to pull away from since they would not work for me.

I also see many guys talk of head tubes, but again it all comes down to leg lengths to.

I am ok with 10mm spacer, but rather not more.

On a bike i had i was force to use 35mm which made the bike ride more twitchy.

I think the bike was a bit to short and somehow my length and position had a bad effect on the handling.

Some guy i have at work is really short and he is really funny when it comes to size of frame.

He rides very very long and tall frames, much over-sized for his length.

But he has raced a 300km race every year for 25 years so i guess he is not off when it comes to his own preference.

Looking at history of bikers, we clearly see that general ideal for a bike fit has totally changed.

Look at the length of the bikes, the reach from handlebar and the drop from saddle to bar.

This is making me wonder how a bike fit really should be interpreted?

No-one could say the very best riders in the -70's or - 80's did not understand bike fit.

But never the less, they would not be fitted like this by recent standards for bike fit.

Also, there must be more of you guys who note that your fit may actually change during the season?

Perhaps not for those who ride active all year, but for us with long off season (and who are not using our trainers as we should)

we surely notice. Clearly interesting this matter!

Not really. The components have though. Today we have more hand positions that are similar in reach then the old bars with deep drop.

Care to elaborate or are you just working on your post count to sell stuff?

while one photo doesn't really prove anything, the guy on the left never seemed to have a problem with power LOL

Yes see my earlier post, on my 1990s Bianchi and Merckx frames the headset adds 45-50 mm to the stack. Allowing for this, but ignoring the differences between quill and modern stems, these two racing frames have around the same stack and reach as my Merida `endurance' frame. In the olden days of 50-75 mm saddle to handlebar drops you got low by simply bending your elbows.

Sometimes the wheel really does need to be reinvented. :)

And there also are riders with a large gut..........that gets in the way of their leg motion if too bent forward...........

(I'm none of the above - I'm 56 yrs old and at 5' 11 have a 130mm drop along with 130mm stem/56cm TT/rearward slammed saddle)

One user here even goes so far as to state that a pro cyclist, who has been a member here for years before that user ever signed up, took their "advice." :roll: That people actually believe everyone's body proportions are the same is only the start of the idiocy. viewtopic.php?f=3&t=136199

I have also read somewhere on this forum that some members believe that if you use more than say 1.5 cm spacers you must be on a bike frame that is too small.
It's all downhill from here, except for the uphills.
