a to a or brace height?

[crh]

Which is more important? I have a Rytera BulletX with the vipro cam. I have replaced the factory string and cable with vapor trails. I can adjust it to get the correct a to a of 34" but the BH is 6 7/8". The brace is supposed to be 7 1/4". I have brought the a to a down as far as 33 3/4" but the brace only gained 1/16". Is this ok or what do I need to do to correct this. Thanks.

With single cams I try to get the tiller even and BH to spec. I always end up within 1/8" of AtA that way, if not dead nuts. But don't forget to make sure it makes DW and DL in the process.

Was your bow to those specs BEFORE you repalced string and cables? Then you should be able to get it back. Remeasure your old strings and cables and compare them to the new ones.

Also, what process did you use to get your A2A down?

How is the cam rotation? What kind of poundage are you maxing out at. What is the measured drawlength. Brace height is the most important of the two in my opinion. If it is off then your drawlength will be off as well unless the cam rotation is out of whack to compensate.

Thanks for the quick replys.The cam rotation is correct according to the pics I have seen on this site with 1/4" of the cam groove showing. The draw on the bow measures 29" which is what its supposed to be. I adjusted the a2a down to 33 3/4 by twisting the string 2 turns for every 1 turn on the cable to maintain cam rotation and nock point. I just can't seem to gain much on the BH. I don't know exactly what the draw weight is I don't have access to a scale, but it doesn't seem to be much more than it was when I got it. I didn't think to measure the bow before I took off the old string and cable.

You may want to contact Martin on this one. That is an extreme parallel bow and you will not gain much if any brace by loading the limbs. The cam rotation is the only way that I can think of to get that brace back but you say that the drawlength is spot on so that will change when you change the rotation.

Did you max out limbs before adjusting ATA? Did you change grips? All factory specs are given with maxed out limbs. Correct ATA and cam rotation should bring in brace height

I called Martin Archery as suggested. I talked to Joel. He gave me the measurements of 7" bh and approximately 33 1/2" on a2a. I made sure limb bolts were tight and I twisted the string and cable a little more and was able to get 7" brace and a2a of 33 5/8". I then shot through the chrono and got 286fps with 370gr cx300 which is within 2fps of what OT2 says the speed should be.I am happy. Thanks for the help and suggestions.

Glad you got it taken care of.:wink:
