Title: High performance bows w/high brace heights?
Post by: Nathan Bowen on April 20, 2011, 08:11:00 PM
Can you guys help me make a list of high performance bows with high brace heights. I know the widow td recurves have recommended brace heights of 8.25-8.75" are there others and how high?
Thanks
Nathan

If a bow is built for high performance then a high brace height is extremely counterproductive. Its basicaly like losing an inch of draw length for every inch of extra brace height over what is needed to give wrist and fletch clearance.

Depends what you consider high. I also disagree a bit with Sixby. Bows with real forward risers naturally have higher braceheights and if you lower them to much it effects the bows performance. I have an RER Arroyo that will shoot with the best out there as far as speed and I have it braced at 8"s. Shawn

I understand that in "general" that lower brace heights help with faster arrow speeds but I also know that the taller brace height makes for a more forgiving bow. Also if you can get both all the better. Any one know of any other examples?

Then again... if the design was to be fast (which is what I am interpreting as "high performance" in this thread) and IS fast at a high brace... then that would mean it would also be somewhat forgiving because of the high brace... which is never a bad thing... and we all know that the Habu is definitely on the fast side.

I once had my first Hill longbow set at 8+", before I knew any better. It still smashed some goats.

Our Annawaekee Addiction recurves and my bob lee, 15" riser and 64" limbs have 8.75" or therabouts, Annawaekee Addiction LB in 8.25"  This is not an absolute and depends on a myriad of components: Riser shape, limb length, bow length, personal preference etc. Most deep riser bows will run over 8". I have shot over 9" some with the BobLee.  For what its worth!?

The only way a higher brace height makes a bow more stable is by increasing center shot and slowing down the arrow.

Forward-handle bows tend to be more stable, but it's not because of the brace height.

The reason so many bows have a higher brace is because the design of the particular limb is not verticaly stable at a lower brace. If you have a limb design that has stabiliy both horizontaly and verticaly at a lower brace and it is still a hight performance limb that bow will shoot faster at say 7 inches brace than 8 12/4 in brace. When you talk performance it has to be pulled from every part of the bow without compromising the shootability or integrity of the bow. I build a belly mount recurve bow with a 7 in brace It took a lot of r and d to get the limb to work and to get good stability at that brace but it is and it shoots great with a 7 in brace. Jeff I agree to a degree with your statement . It gives the arrow more room to bend. Actually the right way to take care of that problem is to build a riser with 3/16 past center cut.
God bless you all and Happy Easter. Steve

So bows with a high brace height have a flawed design?

So is that to say that a bow's brace height is a byproduct of it's design and not relative to it?

I was under the impression that using a brace height on a bow that is outside of the normal parameters of it's design was what caused unstable or noodly limbs.

  :dunno:

Actually the last statement is exactly what I said. It is outside the parameters of its desing. So design it to have good stability at seven inches instead of eight. That is my point. Thanks and God Bless you, Steve

That's why Olympic recurve bow shooters shoot bows w/ a 7'' brace?????? but what do they know!
So why wouldn't you design a bow w/ a higher brace that will perform w/ bow's w/ at a lower brace.
