Frame size?

davekdk

Howdy,

Have been off the bike scene for a good number of years but getting back in now and going to purchase a road bike on the BTW scheme.

In the past I always like a 17" frame because for some reason I felt it was more aerodynamic to be bent over on the ride. I am 5'10" in height myself. Some people used say this wasn't such a good idea.

Can anyone advise what the most suitable frame size is for a 5'10" guy?

Thinking of getting a Trek 7.5FX looks like a nice machine!

Cheers.

17 inch, is that a mistake ?

Everything is in metric these days, 17 inchs is maybe 42 cms......


Lance Armstrong is 5''10 and he used a 58cm frame, its not an exact science, go to the bike shop and find out what you are comfortable with

I'm the same height as Lance (and you), and I ride a 56cm.


No point in getting a frame too small (thinking it will make you more aero dynamic)

There are other ways to make you more aerodynamic, like lowering the handlebars or getting a longer stem.

a 17" mountain bike maybe, but a road bike as already said you would be looking at a 56cm frame or there abouts depending on your proportions.

It can vary slightly depending on the brand, i'm about 6'1 and had a good fit on a medium Giant, i now have a 58" cube which is also feels good but am almost maxing out on stem and seatpost.

I'm 5"10 and use a 56cm.

Measure your inside leg, in cms. then multiple it by 0.69 (for a normal frame) or 0.64 (for a sloping tube frame). this will get you close.

There is not definitive chart or size of a frame based on your height as it really all depends on your leg and upper body sizings.

Example. I'm 6'1 and I've a 55 frame one on bike and a M on a Giant CR frame (which roughly equates to a 55. The reason being my upper body size. Technically I should be using roughly a 60 frame but when I do I always find that I'm stretching far too much on the bars and my back does be in bits. I much prefer a 55.

Go to the store and try it and whatever feels most comfortable get it.

i'm 5'10 and my road bikes are 56cm, rode a 58cm for years mind

i was always ttold i should ride a 17" mtb but ended up racing on a 19" could never get comfortable on a 17

I just ordered a Cube SL Cross Comp 53cm today.
Took a spin on the 56 first then a 53 and much happy with the 53.
Sure you can just raise the saddle.
Lower centre of gravity = more power to the back (so the guy in the shop tells me!)
Cheers for all the re plys!
