Splitting Vintage

Every once in a while, I'll walk by a seemingly-ordinary bicycle parked somewhere or another and, without knowing why, turn back to look at it.

That's what happened today at a local library branch.  This is the bike that made me backtrack:






At first glance, it seems like one of the current Merciers.  Not a bad bike, but nothing exceptional:  The welded Reynolds 520 frame sports a combination of inexpensive but functional components.  And the color and trim are rather nice but, again, not exceptional.

However, I noticed an interesting little detail upon looking at the bike for the second time:




The model name is "Galaxy."  Why would I notice something like that?

Well, as far as I know, when Merciers were built in France, there was never a "Galaxy" model.  However, another bike-builder--in England--offered a "Galaxy" model:


Dawes was a family-owned bicycle manufacturer based in Birmingham--the center of the British cycle industry--for nearly a century.  They were known mainly for their touring models; the Galaxy was billed as one of the least expensive stock (what the Brits call "off the peg") quality touring models available.

In materials, design and construction, it was very similar to the Raleigh Super Course, though the frame workmanship, in my opinion, tended to be a little better on the Galaxy.  Also, the Galaxy had, if I'm not mistaken, a somewhat longer wheelbase than the Super Course.

While not as popular as Raleigh in the US, many new American cyclists early in the 1970's "bike boom" bought a Dawes Galaxy as their first "serious" bike.  More than a few were outfitted with racks, full fenders (They came with useless half-fenders.) and lights and ridden on the Bikecentennial.  

What's interesting is that Dawes and Mercier--like Windsor--were bike brands that had somewhat-more-than-modest popularity in the US during that time. Now Chinese- and Taiwanese-made bikes bearing all three of those brands--as well as the hugely popular Motobecane--are sold on the Internet.  

Bikes sold under those brands in the US have no connection to the original manufacturers, which no longer make bikes in the countries in which they were founded.  Mercier, which had a successful racing team, went bankrupt in 1985; the same fate befell Motobecane, which became MBK and now manufactures motor scooters.  Windsor used to build bikes in Mexico based on European designs; its "Profesional" (note the Spanish spelling) was a knockoff of a Cinelli racing bike.  Eddy Mercx rode a Colnago bike bearing Windsor decals when he set the one-hour distance record in Mexico City in 1972.

So Dawes is the only one of those bike brands sold on the Internet whose original namesake company still exists. (Dawes bikes in the UK are sold by dealers and aren't the same as the ones in the US.) It's thus ironic to see the name of one of the most popular models in its history appropriated by a "ghost" bike label--that was based in France, no less!

Another Forerunner To A Shimano "Innovation"

For today's post, I'm going to engage in a bit of bike geekery, as I did in yesterday's post.  Fear not:  This will not be a regular feature of Midlife Cycling.  At least, I don't intend it to be.

As I did in yesterday's post, I'm going to write about a long-forgotten component that featured a design used in later, more successful (at least commercially) bike parts.

From the 1920's until the 1970's, many British bikes featured Williams cranks, chanrings and bottom brackets.  That is not surprising when you consider that those parts were, like the bikes, made in England.  

As Steve Griffiths notes in "Classic Lightweights," Williams has been unfairly judged on the basis of its lowest-quality--and, unfortunately, most commonly-used--model, the C34.  It was a cottered steel crankset, and the arms (or spider) onto which the chainrings mounted was swaged (forced).  Willliams also make much nicer models,including some of those thin,elegant cranks you see on British bikes from the 1960's and earlier.  

But their best crankset--and the only cotterless crankset made in any significant quantity in England--was the AB 77. I have seen one of them in my entire life: on a Claud Butler that came into the first shop in which I worked.  

The AB77 was actually quite nice:  the quality of the materials, machining and finish were high.  It had the same chainring design as the TA Cyclotouriste, Stronglight 49D and the Nervar crank that aped them.  That meant the AB77, like those other cranks, could be set up as a road double with a 42 tooth small chainring  or as a triple with a 26-tooth inner ring.  



But the most interesting part of the AB77 was its bottom bracket.  Presaging a trend by two decades, its axle had a splined rather than square end.  In other words, it was a proto-Octalink or ISIS bottom bracket.  

Unfortunately, that bottom bracket was its fatal flaw.  During the period when the AB77 was produced (1962-mid 1970's), only one other crank had such a design.  It was made by Gnutti in Italy and its splines were of a different pattern from Williams', so the two could not be interchanged.  That was especially unfortunate for Williams, because the bottom bracket, which was made by T.D.C. (once a major manufacturer or headsets and freewheels), didn't last very long. 

When Shimano decided to resurrect this long-forgotten idea during the 1990's, it made the splines broader, which was supposed to increase the stiffness as well as the lifespan of the bottom bracket.  However, they, like their TDC/Williams predecessor, wore out quickly.  The problem with the Shimano splined brackets--and the similar, though not interchangeable, ISIS-pattern bottom brackets made by other companies--had narrower axles and smaller bearings than their square-ended counterparts.  Interestingly, Shimano's Octalink and other companies' ISIS bottom brackets had an even shorter run--not much more than half a decade--than the ones from TDC/Williams.  

A few years after Williams ceased production of the AB77, they were taken over by Nicklin,one of their former competitors, which offered only the C34 and a couple of other low-priced models that were fitted to mass-market bikes from Raleigh, Dawes and other manufacturers.  As production of such bikes ended, so did most of the British cycle-component industry, including Nicklin/Williams.
