A Personal Question of Length?

[NeilM]

Well that one was a faff! Gave me numbers that mostly have no relation to frame sizes you can see on majority of listings or websites. But reach helpful?

Standover height is not really something I worry about, as my frames are all 18", rather than 19.5" that most charts recommend. But the other dimensions are, I feel, all pretty critical.

In respect to those (and other) measurements, all my mtb's are almost identical with only minor variations to allow for slight differences in frame design.

Most should give standover height and virtual top tube length.
But remember that will be modern bikes so long forked and short stemmed relatively.

I think i've shown you the kona charts before.

Nope. . .?

Going by my height, 5'10", I should be on an 18"
Going by my inside leg, 34", I should be on a 20"
Assuming my body was 55% of my height, I should havean inside leg of 29" & I should only be 5'5" Tall & should be riding a 16".

Hmm, maybe I need a custom frame.

I have concluded from this that reach and bar height is more important as there is less adjustment without changing parts etc.

Inside leg varies greatly amongst similar heights but can be accommodated across a range of frame sizes.

Would I be wrong?

 

[NeilM]

Nope, in my opinion you are spot on the button.

Yes exactly, there is one brand of road bikes, where the frame 'size' refers to top tube length rather than seat tube.

There's an interesting article from Cervelo here, where they show that as some frames get taller, they don't actually get longer.

Ok somebody on here tells me I've got short legs for my height. Never gave it any thought until recently looking at frame sizes. What's your inside leg and height?

I am 6'3" with 33" ins leg. Freak?

Please tell me your height/leg for comparison and your mtb and road frame sizes.

Thanks. Picking up 19" mtb at 7pm and wondering.

I'm 6ft with a 32in inside leg; don't own a mountain bike any more but the road bikes I own are 22.5in (race) and 23in (tourer) whilst the CX bike is only 22in to aid dismounting & remounting.
