HP-Turbo: A "Lost" Brake From Weinmann?

If you bought a new ten-speed bike of better-than-marginal quality during the '70's Bike Boom, there's a good chance that it came with Weinmann brakes and/or rims.

Most made-in-Chicago Schwinn bikes had one or both until about the mid-1980s.  So did many European bikes, if they didn't have Mafac brakes or Rigida rims.

Nobody ever got really excited about most Weinmann products:  They weren't flashy, but they usually did their jobs and their prices were reasonable.  The best example of this was their "Vainqueur" center-pull brake, which came on everything from the Schwinn Paramount (the touring model) and Raleigh International to the Schwinn Continental and Raleigh Grand Prix.  It was even found on some bikes from French constructeurs and English bespoke builders, who would attach the brakes to brazed-on bosses.

Probably the one product the company produced that was noticeably different from its competitors was their concave rim.  Its unique shape was said to give it superior strength to other rims.  I don't know whether the shape had anything to do with it, but I know (because I used to commute on a pair) it was strong--and noticeably heavier than other alloy rims.

In the late 1970s, Weinmann tried to modernize its offerings.  That is when they brought out the concave rim.  Around that time, they also introduced their "Carrera" brake, meant to compete with Campagnolo.  The quality was excellent and the finish beautiful.  However, it lacked the flats on the center bolt that allowed the brakes to be centered with a hub cone wrench (a nice Campy feature adopted by other brake-makers). Their quick-release device, apart from its finish, was no different from the one on the less expensive models. It had only "open" and "closed" position, while Campy's could be opened or closed partway to allow for wheels that developed wobbles.  

Another attempt to appeal to appeal to the ultra-high-performance (or simply rich and fashionable) market resulted in their version of the "Delta" brake--which, as "Retrogrouch" and others have suggested, may have been made for them by Modolo.  I never used Weinmann's or Campagnolo's Delta brakes, so I won't argue about the effectiveness, or lack thereof, some users claimed. There is no denying, however, that Campy's version may well be the most beautiful brake ever made.  Weinmann's had a more high-tech (for the time, anyway) look, and was available in black as well as silver.

A few years later, Weinmann came up with another interesting and unique brake:

The HP-Turbo was introduced in 1984.   I could find little information about it (I discovered it in an eBay listing), so I don't know how long it was produced.  I also couldn't find testimony from users, so I have no idea of how effective, or not, it may have been.

From what I can see, it's a centerpull brake with the straddle wire coiled around cams to which the brake shoes are attached.  I am guessing that the cams push those shoes into the rims, and that the arrangement is intended to somehow magnify braking power or modulation by increasing the mechanical advantage.

As I said, I am only guessing:  I may have been a mechanic, but I have never been a mechanical engineer.  For all I know, the brake might have been a revolutionary idea for which the cycling public wasn't ready.  Or, perhaps, some people tried it and found that it was complicated and, perhaps, the cams or other parts of the mechanism clogged with dirt or gunked up with grease. (They don't look very well-protected.)  Maybe it cost as much as a good sidepull brake, which came on about 90 percent of new bikes at that time, or cantilevers, which came on most of the rest of new bikes.   Or people thought it was just too ugly to put on their nice bikes.

Whatever its fate, I am curious about it.  

Workin' It

Some bikes look right only when they've got half of their paint missing and look beat right down to their inner tubes.

Well, all right, I didn't see the inner tubes on this one.  But I imagine that they have, if nothing else, the feel and scent of a pair of flip-flops swished and slogged through curbside puddles during a summer rainstorm.

But, really, can you imagine this bike--from Worksman Cycles--new?  The paint job may have been rather attractive, if in a utilitarian sort of way.  Somehow, though, it wouldn't have looked right.

I must say that in my more than three decades of cycling, I've seen only one "virgin" Worksman.  One shop in which I worked was an official Worksman dealer.  Highland Park Cyclery did a brisk business inside a ramshackle building (which was torn down after HPC moved to fancier digs) at the foot of a commercial strip across the river from the college (Rutgers) I attended as an undergraduate.  Some of the stores and restaurants offered deliveries, some of which they made on bikes.  Those shops and restaurants already had their delivery bikes--Worksmans, mostly--before I started working at HPC.

So it was something of a surprise--to me, anyway--when I found myself assembling a brand-new Worksman.  I didn't mind that:  Although it wasn't a bike I'd've bought for myself, it was easy to work on.  Plus, one could not deny that it was suited about as well as any product could be to its purpose.

What surprised me, though, was that it wasn't a business that bought one.  Rather, he was--as I recall--a married middle-aged man who ran a "consulting business" from his home.  He never consulted me about what his business consulted on, but he seemed prosperous and his family harmonious.  

He said he'd wanted his Worksman to use as his "human powered station wagon."  Later, I saw him hauling groceries, building supplies, books, and even furniture on it.  Another thing I find interesting, in retrospect, was that he was looking to become less dependent on his car (which he sold not long after buying the Worksman) at a time when gasoline prices were falling, at least relative to what they were in the days around the Iran Hostage Crisis.

Although I saw that man on his Worksman nearly every day, it didn't seem to wear much.  Granted, Highland Park wasn't as harsh an environment as New York or other urban zones for a bike.  Plus, I'm sure he didn't subject it to the same kind of abuse as most delivery people did to theirs. 


Apparently, in spite of the fact that the bikes never seem to die, there's enough of a market for new ones that the company is thriving, and did even during the leanest of times in the American bike market, and before the current vogue for "cruisers".  I guess that disproves the notion that if a product is so well-made that it never needs replacement, the company making it will lose sales and stop making it, or even go out of business.  (Some old-timers claim that was the story of Weinmann concave rims and Sun Tour V-GT derailleurs.) In any event, the bikes are being made in the Ozone Park area of Queens, NY, about seven miles from my apartment and just off the route of a few of my regular rides. 

Afterword:  I was looking up Highland Park Cyclery.  Apparently, they've moved up the road into neighboring Edison and have renamed themselves Joyful Cycles, in a reference to 1 Thessolonians 5:16-18.  Ironically, Frank, who owned HPC while I worked there, and his wife Wendy were about as antithetical to religious fundamentalism as any two people could be!
