I have a set of limbs off a Hoyt Rx1 Ultra. They are 205 Deflection limbs, so depending on what cam number and bow model you have (rx1, rx1 ultra), the weight range will differ.
These will be 55-65 lbs on a rx1 ultra with a number 3 cam. If you call Hoyt and give them your bow specs, they will be able to tell you what draw weight range 205 deflection limbs will be. These will also work on a regular Rx1 Bow. One of the limbs had a splinter that I cut off and continued to shoot with no problems, so you get 3 good limbs and one with a defect(see pic).
