When limbs are made for a 17 inch ILF riser and you use a 19 inch riser, do you pick up draw weight? I know you pick up lenght? limbs for a 25 inch riser are used on a 17 or 19 inch riser what are the issues?

If the limbs are rated for a 25” riser and you use on a shorter riser, you gain draw weight.. you lose draw weight if you use on a longer riser.

It should be that simple....but it's not always.
You can go from a 17" riser to a 19" riser and not change draw weight at all depending on the limb pad angle/amount of deflex of the 2 risers.
It used to be that you could fisgure roughly 1lb. of draw weight per inch of riser change, but not anymore. And that's just with recurve limbs.
If you start talking about ILF D/R longbow limbs all bets are off.

I have a white feather 19 inch riser and want to buy a set of das bamboo recurve limbs that are rated for a 17 inch riser. will 35 pound limbs be 35 with the ilf adjustments turned all the way down?

What's the difference in the limb pad angle/deflex of the 2?
If you are buying the DAS limbs from a dealer thay may be able to tell you.
I have a formula that I use to help me get close in those situations, I can PM you and tell you how I figure it if you're interested. But you have to know the limb pad angle and have an idea of the amount of deflex.

thank you!! I forgot about the longer riser issue. Thanks to everyone. I would have bought the wrong limbs thank again.

While I lack experience with ILF limbs, I know when I shorten a bow and cut new nocks it gains weight. Sooo shorter heaver, longer lighter. FDP is right also. Pad/limb angle can make a lot of difference. It can make a little, even if the angle is rated the same. A tiny difference over the pad/limb span is greatly magnified out at the end of the limbs.Plain Geometry. Merry Christmas, >>>>-----> Ken

Best to ask the vendor. I wondered about a pair of TT limbs on a Excel riser. Turns out I only lost about 2 pounds not the 4 I figured using the formula.

In my experience with WFL 19" riser: #50@28" Ex BF - on 17" riser - were #52@28" on it. #44@28" (on 25" riser) are #52@28" on WFL 19".

Depends on whether they are scaled with bolts maxed or half way. I have 2 sets of 50lb medium limbs, but with the limb bolts all the way in, there's a 5lb difference. Trad Tech limbs scales heavier than Greatree limbs.

Seems like with the exception of gain or loss any prediction of how much would depend completely on the geometry of the particular riser EACH manufacturer used to rate their limbs.
