I am working on a UK built 1981 Raleigh Record Ace and it needs long reach sidepulls. It came stock with Weinmann 605s with 27 inch wheels but it will need longer reach brakes if I decide to go with 700c wheels. I do want to stick with sidepulls though. Who makes quality long reach brakes? I assume campy is the go to choice but is there something else out there I should look at? I do want to stick with vintage sidepulls brakes though on this build (no dual pivots).

Usually short reach is 39-49 mm, "standard" reach 47-57 mm, and "long" reach is more than 57 mm.

The Weinmann 605s have a max reach of 60 mm per velobase. I'll likely use these if I stick with 27 inch wheels as they'll work fine with kool stop pads.

Campagnolo NR brakes have a reach of 65 mm again per velobase.

I like the first gen Dura Ace sidepulls but they only have a reach of 57 mm.

Anything else out there I should think about?

Not vintage, but I have used Tektro R559 [ Long Reach Road Calipers (55-73mm) ] on several builds and they work great, giving you a LOT of room. They're dual-pivot as well, so they work with great stopping power.

Tektro R559 is what I use.

They are pretty awful to be honest but they will eventually get you stopped.

Weinmann 730 should work

There are several on ebay at the moment

Mr. 66

I'm not sure if you are right about the Dura Ace calipers, I have those with more reach than the Campy. I have a bike from '72 that the standard reach Campy was not enough yet the Dura Ace is enough.

The info is from velobase but it could be wrong! I'll measure a set.

...Weinmann made something called "the 810" that is the longest reach side pull brake I've seen. I used them once, when converting a Raleigh Sports over to standard 26" mountain bike rims. The only ones I could find at the time were anodized in gold, but for my purposes, this was not especially problematic. I guess you can find them on ebay, but they will be overpriced. They got used on a lot of lower end department store bikes, that were sold with 26x1 3/8 wheels.

I think I have Weinmann 810 side pulls on something in the fleet, but they are very poor stoppers. Arms are just too long to provide good leverage.

Here's a page from Velo Pages (https://www.velo-pages.com/main.php?g2_itemId=29007) I found when checking Weinmann 500 info.
It's from the 1981 catalogue - look at the top left corner

How about Dia Compe BRS 202. 57mm to 75mm length.

I've been using a DiaCompe 806 on the front on my Peugeot for a while but it flexes alot and the arms are way beefier than the ones on the 202. Not liking the cable pull with a Sram lever either.
I'll swap mine as soon as I find a suitable dual pivot caliper with a 60-62mm drop, but most likely going to be a centre pull caliper.

I think they stop great and I'm 210lbs. Must be different than mine or maybe I have really low standards.

GhostRider62

Ok. Worst brakes I have ever owned. They are fair at best. Flexible as hell. TRP RG957 are better but these are only good to 59 mm reach but they can be extended 4-5mm with pad droppers.

NOT vintage, and dual pivot, But this info may help someone. Tektro 900a nutted road bike calipers. 72mm-92mm long reach. I looked alot for the 810,890 calipers and couldn't find any, These Tektro's are still available. I have two sets on older Raleigh bikes using 650 b wheels. One set on a '56 sports and one set on a 70's international. They work pretty good, but not great. Kool stop pads help a bunch. I also ran across some HUGE Tektro C324 dual pivot side pull brake for extra long reach applications.98mm-116mm .As the reach gets longer, the braking force gets lower and the bending moment is greater. Thus performance goes down.

Another vote for the Tektro dual-pivot route over any long-reach sidepull.

The R559 is the nicest looker and accepts cables from the left side of the caliper. The 800A or 900A are more budget oriented, do not have built-in quick releases, and their finish is "mid-1980s Weinmann entry level" - but if you need right-hand cable entry, they're the ones to choose. You can sometimes find them in black as well:

Dia Compe FS-E

These are on my Performance Parabola. The max reach is about 75 mm and they are dual pivot.

Dia-comp makes a double pivot sidepull, DL800 with 79mm reach, It has a traditional nut., and does not have a quick release, They also make a recessed nut version with 75mm reach and quick release, They are on the Soma fab site .For some 27' to 650B conversions, the 73mm reach Tektros aren't quite long enough. I personally prefer centerpulls. Weinmann or Diacomps are okay.. MAFAC Raids and the copies are better. Brazed on centerpulls are the best.

Vintage Schwinn

As branko 76 mentioned the WEINMANN 730...........****THIS WEINMANN 730 is EXACTLY THE SAME AS the Weinmann sidepulls marked L.S. 2.4 , seen on all 1969 and later 27" wheel(630mm) VARSITIES and Schwinn SUBURBANS.
---------What Schwinn did was place their own internal code on to these sidepulls beginning with the 1969 MODEL YEAR.
For example, look at a 1968 VARSITY and they will be 730 and the 1969 VARSITY will say L.S. 2.4,----------------they are exactly the same!!


Now the 26" (597mm) 26 x 1 3/8 S5/S6 (37-597mm tire) Collegiates, Breezes, etc and similar variants do have the WEINMANN 810 in 1968 and L.S. 2.8 in 1969!!!
They are all the same!!!

1969 and later Chicago SCHWINNs have this internal Schwinn code marking on them.

Here is what that internal 1969 & later Schwinn code mumbo jumbo when deciphered tells you:
For Example: the L.S. 2.4 (weinmann 730) from '69 on VARSITY & '70 on SUBURBAN
The L letter (first letter tells you what type of Schwinn bicycle that it is applicable for, here L means for "lightweight" Schwinn models....)
The S letter(2nd letter being S tells you it is a SIDE PULL)
Okay about the NUMBERS SEEN THERE (it isn't what you might be thinking......follow along and you'll get it even if you are Jethro Bodine and a 6th grade grad-gee-ate:
NUMBER to the LEFT of the decimal INDICATES in INCHES the Distance from Mounting Bolt to Center of Brake Slot Area....BUT WAIT You Gotta ADD MORE!!! :
NUMBER to the RIGHT of the decimal GETS MULTIPLIED by 3/32 inch...........................Don't Get Confused so for this example it will be 4 x 3/32..........
Okay 4 x 3/32 = 12/32 , 12/32 reduces to 3/8...............yeah you know from 4th grade math class that 12/32 = 3/8
.....Okay now what the hell do you do with this 12/32 or 3/8 ??
.....YOU ADD 3/8 to that 2 inches that the number LEFT of decimal TELLS YOU.
................So 2 3/8 inches from the mounting bolt to center of brake slot on the normal* 27(630mm) wheel VARSITY Weinmann SCHWINN L.S. 2.4 (weinmann 730).
* = does not include the juvenile-young boy's 24 inch wheeled VARSITY that was available for some model years!!!
I TOLD YA THAT IT WASN'T WHAT YOU PROBABLY THOUGHT THE CODE MEANT, KINDA FUNKY CODING FOR INCHES & 3/32 inch for each number to the right!!!

.............Now you know, hey check it out though, it is an accurate enough funky code though, go ahead and measure an old Weinmann 730/L.S. 2.4 from a Varsity or whatever bicycle and I think you'll come up with 62mm if you are using a metric ruler..... 62mm is pretty damn close to 2 3/8 inches
So say its 62mm to center of brake slot, and so maybe 53mm to highest point and so maybe 71mm to lowest most point in the brake slot of the L.S.2.4(weinmann730)



Now for EXAMPLE of the L.S. 2.8 (Weinmann 810) from the COLLEGIATE/BREEZE and similar 597mm twenty-six wheel variants:
You know that L stands for "lightweight" Schwinns, and S stands for SIDE PULL
NUMBER to LEFT of DECIMAL, tells ya that 2 inches, but WAIT, BECAUSE YOU GOTTA ADD MORE.....you gotta add (8 x 3/32)....you gotta add 24/32....
That makes it 2 24/32 or 2 3/4 inches because you know from 4th grade math class that 24/32 = 3/4.............so it works out to 2 3/4 inches for Collegiate ..etc
..........So 2 3/4 inches from the mounting bolt to center of brake slot on Collegiates/Breezes and similar variants with 597mm wheels.
.....................so hell, my guess is that if you were to measure a Weinmann 810(L.S. 2.8) with a metric ruler that you'd probably get something pretty damn close to 70mm for that distance from mounting bolt to center of brake slot on the Collegiate's/Breeze's side pull Weinmann 810/L.S. 2.8 .
I am certain that you are not a dummy, and that you can figure out what the highest and lowest points in the Weinmann810 / L.S. 2.8 would be, just knowing the center point and extrapolating what you know off the top of your head on typical brake slot size area.




Now, certainly the old Weinmann 730/L.S. 2.4 (VARSITY) sidepulls and the Weinmann 810/L.S 2.8 (COLLEGIATE) sidepulls ARE VINTAGE ANCIENT TECHNOLOGY but might be perfectly fine for low technolgy and vintage bikes where you aren't gonna haul azz down the 11 miles of Tail of The Dragon in Western NC and East Tenn........but oh wait they don't currently allow bicycles, though people have done it on bicycles before.
Unless you're gonna go all kamakazee , going down very steep grades(hills) at speeds approaching 40 mph or greater.........................lets just say that you'll be fine with said ancient antique WEINMANN side pulls if you are gonna just ride something Varsity like from the '60's/'70's/'80's at a typical cruising speed of 14mph to 18mph.
IF HOWEVER THAT YOU DO FEEL THAT YOU HAVE THE NEED FOR SPEED, THEN YOU SHOULD POSSIBLY CONSIDER CHOOSING THE BEST-MOST MODERN BRAKES THAT ARE PRACTICALLY APPLICABLE TO YOUR PARTICULAR BICYCLE.

I've seen those huge tektros a couple of times at the local non-profit. As far as I can tell, they were designed for beach cruiser frames. Kind of fitting really - they were veritable boat anchors. Great first post!

dddd

Altenberger Synchron long-reach calipers extend from 65mm to 85mm and feature a true dual-pivot design.

The shorter version reaches from about 55mm to 75mm.
