Question Mountain bike frame size question

Thanks for all the replies to which mountian bike for 300ukp thread

OK then taking some advice from the thread s/hand seems to be the way to go.

1 am 5'11" tall, 31.5" inside leg, what sort of frame size would be ideal, difficult to get out to check/test ride at the mo.

I am pretty sure 19-20" frame is right, can anyone confirm, it is for recreational riding with some off roading.

Paul, you might find that size frame a touch on the large side. I'm 6'1 with a 19" frame on my Trek and find it about as big as I can manage - certainly wouldn't want anything bigger and I would probably find an 18" frame fine.

Strongly advise you to try before you buy if you can.

My usual rule of thumb is the smallest frame you are comfortable on. You can always raise the seat and change the handlebar stem to give more reach.

The advantage of a smaller frame is that it's stiffer, lighter, easier to handle, etc. I'm 6" and ride a 15" or sometimes a 17" MTB and 56cm road bikes.

Thanks chaps, that certianly opens it up for me, looking on fleabay and been discounting anything smaller than 19, sound like 17-18 would be just fine.

Many thanks

I think the key is what you'll do with it. A bigger frame is more comfortable pedalling long distances, a smaller frame is more agile as you hurtle downhill avoiding rocks and trees

I'm 5ft 11 and I tried a few sizes, found a 17" frame to be the most comfortable.

it depends how they're measured too, some manufacturers use different methods.
A higher frame usually has a longer reach, therefore affecting your riding position. You sometimes get bigger disks too.

I'm 6' with about 32-33" inside leg, and ride a Large Spec Stumpy (dofferent with full sus, as they squat down when you sit on them), and a 19" Spec Rockhopper. The latter is mainly for commuting, and is if anything a touch small to be ideal.
a 19" Trek though could be totally different.
you do get used to positions, but you really need to try a few. If you like a taller frame (I'd say 19" for you), but the reach is a bit long, you can put a small stem on.

I'm 6ft 2 and ride a 19" Rocky Mountain Element 70, stick with the smallest frame you can get away with, it'll be lighter and stiffer.

If i was you i'd not go above a 17"

It's all about the "bollock-room" not the stiffness of the frame, that just means it's harder when you hit your b.ll..ks...

Trust me !
