Title: Another ILF question
Post by: KyRidgeRunner on November 24, 2017, 08:53:00 PM

Ok guys.  So I have a trade in the works for a VPA riser.  It’s a 13” riser.  When I look at limbs it seems they mostly say the pounds on 17” (i.e 40lbs on 17”) so if I’m going to be dropping to a 13” riser does anyone know what poundage limbs I would need to land in the very low 40’s? I’m assuming something around 30-35lbs but I really have no clue.  Any help is appreciated

Rule of thumb......for every inch of riser you gain or lose a pound. 17" riser 40#.....13" riser 44#. If you go up 19"riser 38#. Plus you have a bit of adjustment + or - about 2 pounds maybe a bit more. Now some risers have different pocket limb angles so that can make this all different. But you won't be to far off.

I have two vpa 13 " risers and find due to limb pad angle you will be close to marked spec on most limbs.

Most ILF limbs are actually rated on a 25" riser so make sure the limbs you are looking at are rated on a 17" riser.

35# on a 25" riser would be 47# on a 13" riser.
