This part gets confusing so ask for clarification if I don't explain well.
1. Each Manufacturer will rate the poundage of the limbs on a given riser length. For example, most Olympic Recurve limbs will be marked for a 25" riser. Tradtech limbs are marked for a 17" riser. So you need to verify what length riser the limbs your buying are marked for. In this example a 40 pound set of Tradtechs and a 40 pound set of WinWins will weigh very different from each other on a 21" riser.
2. As riser length shortens the poundage of any limb will increase, and as the riser lengthens the weight will decrease.
3. I wish it was a direct science, but each riser manufacturer will increase and decrease at a gi en length differently. This is due to the limb pad angle on the riser and amount of reflex of deflex.
4. A good rule of thumb is 1.25 pounds per inch of riser change. So a set of limbs that are marked 40# on a 25 inch riser, would be close to 50# on a 17" riser.
For what you are looking for, I would reccomend the following. I'll give two scenarios.
If you buy limbs marked for a 25" riser...
I'd buy a 21" riser, long limbs, and have the limbs be in the 35-40# range.
If you buy limbs marked for a 17" riser....
I'd buy a 21" riser, long limbs, and have the limbs marked right around 40-45#.
Man I had to read that several times haha. You explained it well, I’m just wrapping my head around these concepts. So knowing this, manufacturers are marking their limbs for a specific length of riser in order to have consistency in the draw weight and total length for those limbs on that length of riser, correct? So technically, like you suggested, I don’t have to use the recommended length of riser for certain limbs, but I’ll need to account for the draw weight change that happens if I go with a different sized riser than what the limbs are marked for. Am I on the right track?
I’m looking at a 21” cheap riser right now and limbs marked for a 25” riser (they say 70”, so I’d end up with a 66” total length) and the limbs are 34lbs. That sounds about like what you’re describing. I’m guessing the weight I’m actually pulling would be closer to 45lbs by the time I factor in my long draw and the shorter riser.
