Reflex Riser's???

[Schme1440]

Why has no one ever mad a reflex riser or why have they never taken off?

[Kae]

Would that not effectivley shorten your D/L, thus shorten the powerstroke and thus be very slow?

Dunno, just guessing, Kae.

No it would make it all longer as it would pus the limbs further forward. It would make the limbs work harder.

Could be something to do with the following:

"202.c.ii (The Arrowrest):

The pressure point shall be placed no further than 4cm back (inside) from the throat of the handle (pivot point) of the bow."

From the Recurve section of the GNAS Rules of Shooting

Where is the pivot point on a reflex riser?

I was looking around and found this on the Merlin site:

"It has always been assumed that a re-flex riser torques more than a de-flex riser."

Its about compounds but I guess the basic theory is the same?

The grip would be the pivot point no?

Dunno, that's why I asked! You're probably right.

Don't Mongolian/Scythian/Hunnic style bows have reflex handles? Any definable characteristics from your knowledge of that type of bow?

But the article goes on to say

"It is not the reflex riser by itself that creates a bow more critical to shoot, it is the brace height that effects the torque of the bow"

and
"A reflex riser with a larger brace height would give...the same characteristics as a deflex riser of the same brace height"

Hmm

Do you mean recurves? There are quite a few reflex compounds around.

Given the same length and angle of limbs, a reflex riser will have a lower bracing height than a deflex riser. The lower bracing height makes the reflex riser faster but less forgiving. You could get past this by using longer or more parallel limbs to push the brace height up, but these measures would pretty much nullify the performance advantages of the reflex riser. So I suspect the reason we haven't seen reflex recurve risers is simply that there's no real advantage over deflex risers.

Ah! So reflex riser = the FX limb of the riser world?
