Bear takedown riser lengths

[ozy clint]

Can someone please tell me the length of each of the risers?

example for numbers sake- A- 17", B- 19", C- 21".

[Orion]

You got the first one right.  I think a B riser is referred to as 21 inches and C riser is two-three inches longer, i.e., 23-24 inches, or longer.  My A and B risers aren't exactly 17 and 21.  They're about 16 3/4 and 20 and 5/8 as I measure them to the end of the limb brackets, which is the longest dimension.   Close enough. 

[ozy clint]

I did a google search and someone mentioned that a B riser is 4" longer than the A riser.

If the A is indeed 17" then perhaps you're right that the B riser is 21".

If so the B is longer than I thought.

[Orion]

I own both risers.  I am right about those lengths.  Don't know about the C. Folks generally have a preference for one riser length over the other.  I prefer the A riser with no. 2 or 3 limbs for a 58- or 60-inch bow.  The B riser with no. 1 limbs also yields a 60-inch bow, but it's a bit heftier.  Of course, you can make a 62- or 64-inch bow with no.2 or 3 limbs on a B riser if you have a long draw length. If you're concerned about weight as well as length, you might look for an older green stripe riser.  Green stripes, built in the late 70s and 80s, are generally a little more svelt and a tad lighter than the B risers being built now.

Not exackely what you are looking for, but handy information nonetheless .

kop.  Given your Bear chart, I have no idea how Bear measures its riser lengths.  I can't find a 14-inch measurement anywhere on my A riser.  I can get 13.5 inches if I measure from the base of one limb bracket to the base of the other, but of course, the bracket bases themselves extend another 1 1/4 each beyond that, and given their shape, the pivot points of the bracket latch another half-inch beyond that.  Maybe Bear is measuring to some imaginary point somewhere in the limb pocket channel.  Don't know.  However,  if one measures the actual physical length of the entire riser, the lengths I posted above are accurate.  Now I'm confused as well.

That's weird .....

An "A "riser measures 15.5" to 15.75" depending on measuring the actual riser length or end to end of the brackets.

The "B" riser is 19.5"  and the "C" riser jumps up another 4"

About a year ago or more, they came out with the Fred Ikler  riser which is 17.5" , but they do not build a 21.5" riser at all.

I have no idea where you came up with that Bear chart, or how they came up with those numbers.     Kirk

I bought the Eichler with # 3 limbs. Makes a 62 inch bow. I took a few measurements. Maybe this will help a little. I guess it depends where you measure from. The riser itself or the end of the limb brackets.

[shick]

Back when,  the A handle was considered 16" and the B was 20";  since the Eichler handle came about,  Bear calls it a 17" riser, making the A 15" and the B 19".   Your call on what you have.

Kirkll.  I get about the same lengths if I measure to the outside base of the limb brackets -- 15 3/4 inches and 19 5/8 inches.  However, the pivot point, which occurs higher up on the latches, adds about another half an inch on either end to the total length.  That's how I arrived on my figures of 16 and 3/4 and 20 5/8. Apparently, Bear doesn't incorporate that into it's calculations.  You may have put your finger on how Bear measures its risers -- to the outside of the limb bracket bases, rounded up to an even number, i.e. 16 inches and 20 inches.

Interesting Shick.  Maybe they're now rounding those numbers down to get whole number book ends to the 17-inch riser, as you suggest. 

Glad we got that solved.

Not sure if its that big a deal overall.The riser lengths are what they are no matter how you measure it.Ther gonna be essentially the same from riser to riser whether its an A riser,B or the least popular C.

The bowstring lengths are typical and or consistant on the Bear A or B riser and any limb for any of the 56,58,60,62 or 64 inch bow lengths going from the A or B riser and paired with the #1,#2 or # 3 limbs.No need to split hairs.   

[Kirkll]

I have built a lot of aftermarket limbs for these risers, and believe it or not, they are all a wee bit different. The riser lengths themselves are pretty consistent, but the brackets mounted to the end of the riser will vary a bit. It may only be 5 or 6 thousandths of an inch one way or the other, but that can seriously effect limb tracking on recurve limbs moving the limb tips as much as a 1/4” off center.

Even the mag risers and the Fred Ichler risers vary from one to the other a wee bit. I would imagine that many guys that have interchanged different limbs on these risers have experienced problems with alignment.

The only way I’ll build limbs for these is having the riser in my shop and adjusting the alignment to that particular riser. It’s the only way to insure proper alignment. And they cannot be interchanged with other risers.    .02 cents worth

Interesting.  I've gone through a few risers and sets of limbs over the years.  Down to one A and a B green stripe riser now and five sets of limbs.  Though I have had some problems with fit -- limb base too long (one set), slot in the limb base not cut deep enough (new set of black white tips) and a bit of sloppiness caused by too thin bases (quite a few sets, particularly newer limbs)-- I can't say as I've ever noticed an alignment problem, and I do check for that.  Perhaps there's enough play between the riser limb base channel and the limb channel cut out to allow the limbs to self center when strung. Did have one riser where one of one bracket seemed a bit off center, almost bent, but it didn't seem to affect the strung limb alignment. 

I test by drawing the bow and letting down  the string slowly, watching for how it returns to the slot cut in the belly side of the recurved portion of the limb.  I also look down the string from one end to the other on the strung bow.   I also check to make sure the limb recurve slots aren't cut off center.  Did find that on one limb of a pair.  Now you've given me something else to worry about.

He hee.  I'm OK.  Really.

I can't remember seeing the charts before. and have a number of the limbs and most of those marked for #1, 2, 3 for A and B risers differ more than 2 lbs,  I am looking at a set of NEW Red tip #1's that are 57# on an A and 53# on a B, but a set of #3 white tip from Grayling are 63# on an A and 59# on a B.  I'll bet they never expected there would be so many variations. I think they have made changes to the recurve and profile of the limbs, not reflected in the charts. Maybe the charts were made up in FL and not MI.  I will look at the other limbs and see what I find, and check the weights on some.

[kopfjaeger]

I can't check a A-Riser and a C-Riser because all I own is B-Risers. But here is one of my B-Risers.  Lot depends on where you're measuring from.

I measured on my 2016 Bear Takedown from end of bracket screw to end of bracket screw it's 20". If I measure from back of bracket end to back of bracket end approx 19 1/4". If I measure from the end screws that go into the wood riser it's 18" like my chart says.

I guess it's a matter of where Bear Archery measures their risers from.

[Orion]

Hud.  There's always been a difference of about 2# for the same limbs on an A vs. B riser, i.e., 2# heavier on the shorter riser.  The 4# difference you note is larger than usual.  Don't know why that would occur.

The limb profile hasn't changed.  I can lay new black/white tip limbs on top of 40 year old red or white tips, and they match.  However, limb width is a little narrower on the newer limbs.

[kopfjaeger]

Lancaster Archery Supply says an A-Riser is 16 3/4", and a B-Riser is 20 1/2". 

I guess the best bet is to contact Bear Archery and ask them how they measure their risers.
