View Full Version : Max draw weight

Would like some input on where the limb weights end up when maxed out. My "other" bow has 60-70 lb limbs and maxes out at 72. Trying to figure out what limbs to get. I got a call from the Martin dealer today & they said the 2011's will be in Wednesday. No leftys, but come in and look. They are only stocking the gold series bows. My theory is that a bow is designed to be more efficient at peak draw weight. So does anyone know where these will max out?

I have seen a few peoples comments in various threads & can't seem to find them. Seems to me I seen a comment where a set of 50 pound limbs maxed out around 58. If this is true I could go with 50's instead of 60's. See where I'm going with this?

The ones that I've gottn in so far have all maxed at 1-2# over the marked DW. Exile, Onza, FC 400 and FC 360. I think the one mentioned that maxed 8# over was either an exception or the cables may have been a little too short.

I use the 3lb rule. If it is 3lbs or under its OK. If it is over then untwist the cables and make it right.

To clarify things, untwisting the cables would only work on the hybrid cam bows; on a single cam you would untwist the string, changing cable length changes the cam rotation(timing).

No. I don't see where you are going with this.

If the sticker says the bow is supposed to max at 60#, the bow is supposed to max at 60#.

It's that simple.

If you want to make it complicated, cam timing can make a bow max higher or lower than the sticker says, but it also changes the draw length and if the bow has a stop peg, it will change the valley and let-off as well.

If you want 60#, order 60#.

So basically somewhere between 1-3 pounds variance is the norm with Martin? Looks like 60 pound limbs are in my future.

What are you talking about?

Single cam bows have a cable. Changing it's length does the same thing on them, as it does on any other cam system.

From what I've read and heard ALL manufacturers exceed maximum weight to some point when the limb bolts are completely tight. Was just looking for a guideline to use.

"No. I don't see where you are going with this." If the 50 pound limbs bottom out at +8 I will not need to get 60 pound limbs.

You are correct, most manufacturers bows will max 1-2# over the stated DW. Martins are the same, not sure why the one maxed 8 over. If I had to guess.....the string and cables were probably out of spec. If you want to shoot around 60# with the limbs tightened down, order the 60# model.

Not with the IDLER wheel on top, it's a little different.;) I should have said twist the string and cable.

That bow was my new Rytera Nemisis. I ordered 50# and it maxes at 58# on my scale and the one at Kinsey's Archery. It has 175 Barnesdale limbs. By comparison my Alien Z has 195 Barnesdale limbs and peaks at 53#. This is one of the issues I took up with Joel on Friday and I am being sent a pair of 195 limbs. Now don't use these numbers for Martin limbs. If your bow is sporting Martin limbs they will have a different limb deflection code.

So to answer Nutty's question, if the limbs are the right ones and the rigging (string/cable) are twisted properly to specs most bows will peak a couple pounds over the bows rated peak weight. There is some variance in the industry with plus or minus a couple pounds being acceptable. So a bow rated for 45-60 may end up anywhere from about 58# to 62#. Two pounds either way isn't going to hurt a darn thing. It can be changed simply by changing string and/or cable length a hair.

It's similar to automobiles. EPA rating might be 35 mpg. One might get 38mpg and one gets 33mpg. Both are within acceptable limits.

No, it's not any different.

Shortening the cable, retards the cam.
Shortening the string, advances it.
Shortening both, doesn't change cam timing at all. It just reduces the ATA length.

That is the same for every cam system, on every bow. The only difference with the single cam, is that there is only one cable. That means there is no second cable to adjust for cam sync.

Cam timing, and cam sync, are two different things. They are related, but you need two cams, for sync to apply.

We agree, that's what I was trying to say; I just didn't do a good job between my two posts.:D

And if there isn't a second cam to sync, there is a difference; like I said about the IDLER.

Looking at my second post it should be untwist the string and cable. This whole discussion was about reducing preload on the limbs. My bad.:p

Very informative stuff here. I did not know you can change draw weight by twisting the cables. One to two pounds is very acceptable anywhere. I guess I'm just weird, picky, or anal, but want to make the right choice for what I'm looking to buy. I don't like gaps between the riser and limbs for several reasons, and feel the performance is better on the top end.
We all know five pounds doesn't sound like much but feels very different.
and can make a huge difference to the shooter in fatigue and/or comfortability.
