A 1940’s/50’s Mercier Meca Dural

2015-12-31 002

This French Mercier bicycle has captured my attention.  It is made from duralumin – the same stuff blimps were made with – by Meca Dural using a unique procedure to join the tubes with aluminum lugs and wedged steel internal expanders.  The Meca Dural company produced aluminum frames from the 1930’s through the 1950’s on behalf of a number of cycling manufacturers, Mercier being one of them.  A Mercier Meca Dural is included in the Embacher collection (which was sold in its entirety at auction, earlier this year).  The blackbirdsf site also has photos of a variety of duralumin frames of various manufacturers, including Aviac and Barra, as well as Meca Dural.

This Mercier Meca Dural is a “ladies” bike with a step through frame, although it is not a mixte frame as it lacks the set of extra chain stays typically used to stiffen the frame.  Depending on many factors, this may or may not be a good thing.

The bike features a Stronglight crankset with 46 teeth, CLB 700 brakes with useful and ingenious quick release mechanism, Atom hubs, Samir Saminox 700c rims, Huret plunger/pushrod derailleur, a 4 speed freewheel, and a serial number on the left side rear drop out – 16822.  Here are some photos of the components:

Mercier fork

Steel fork with lugged chrome fork crown, amateur paint job, Stronglight headset

The bike has a number of issues which will affect the restoration process.  The steel fork was horrifically spray painted gray  – so the paint will need to be removed.  Upon closer examination, I have concluded that the wheels are not original to the frame.  There is a 1975 date code on the Atom hub, and not only that, their diameter suggests that this bike was built for 650b wheels and not 700c – the fork crown and rear brake bridge daruma bolts foul the 700c tires.  Clearly the bike was built for 650b wheels, which I confirmed after measuring the CLB 700 brake reach.  And, some features are missing –  the fenders show that the bike originally had a rear and front rack, and the fork mount dynamo is absent, as well as the original chain guard.

Even so, I am looking forward to restoring this machine and to its first test ride, as I want to experience the feel of the aluminum frame and steel lugs, and to judge the frame stiffness for myself.  Stay tuned!

Bridgestone XO-5

Bridgestone XO-5

In the past few weeks, I have had the opportunity to see two of my former bikes back out on the road.  This Bridgestone XO-5 was a great bike, and suffered only from low end components.  I originally planned to keep it, after upgrading the drive train with a SunTour Sprint crank (with color matched gold chain rings), adding aluminum fenders and Brooks saddle, and few other features.  But, the frame was a tad too big, so I sold it a few years back.

To my surprise, I  spotted the old XO-5 on my commute route, the first time while riding my Terry.  The bike and rider passed me in a blur of speed.  I started a sprint to try to catch up, but bike and rider were gone in no time, passing ALL other riders out there – even the big ones on their fixed gear bikes.  Then, about a week later I saw her again, and was able to speed up to catch her as she passed me (riding the Meral this time).  I let her know that she was riding my old bike, and I learned that her husband had purchased it (from me) a few years back and given it to her as a Mother’s Day gift.  She rides it every day, and quite well from what I observed. It was fun to connect with her. She loves her bike!

Claud Butler touring frame, 1980’s

Around this same time, I saw a bike photo posted on the Society of Three Speeds blog, with a frame that looked so familiar.  I had donated this Claud Butler Reynolds 531 frame and fork to the Community Cycling Center last summer.  When I originally purchased this 80’s touring machine, the bike looked terrible and had clearly been neglected.  After dis-assembly and cleaning, the frame looked fantastic, but the steerer tube’s threads were damaged beyond repair, having been fixed with brass filler once before.

So I decided to let someone else have a go at this nice old frame, and here is the result.  This is another great example of a thoughtful reinterpretation.  The new owner used an internal hub for the gearing, and a front dynamo hub to provide lighting, plus a nice new chrome fork.  It looks fantastic, and I hope to someday meet the owner of this great bike.

The joy of seeing these bikes being put to daily use, and treasured by their owners cannot be surpassed, except maybe when I am riding one of my own lovely machines.

 

Riding the Old Peugeot 650b Mixte

Peugeot 650b Mixte

I have put off making some final adjustments to this vintage Peugeot 650b mixte, knowing that I needed to dial in the Jeay brakes and work out the other little bugs that always come up during a frame up build.  But with today’s unnaturally warm weather, I decided to take the bike out into the wiles of Portland.  Even though this Peugeot is positively a city bike, Portland’s traffic scene and “bike culture” are in no way conducive to safe and leisurely riding on this type of machine.  So, a weekend trip along Springwater corridor and through the Eastbank Esplanade is the most enjoyable way to learn the handling characteristics of a new ride such as this.

I am not sure why it is so tempting to think of a 70 year old bike as clunky and incompetent, but riding this machine today reminded me again how well the cycling industry had developed by the time the Germans occupied France in 1941.

First of all, this is no clunker.  It weighs 28 lbs as pictured (without bag), and that includes the fork mounted dynamo, fenders, and heavy Gauthier leather saddle.  Not bad!  The frame is made with Vitus Rubis tubing, which was used on higher end models in the 30’s and 40’s. The front end had no unpleasant “wobbly” feeling as can exist on some mixte frames, and handling was easy at all speeds.  Maybe the long wheelbase and super slack seat tube angle provide for the comfortable ride – but it is really fun to corner on this bike.  Kind of like riding on a roller coaster.  Whee!

The Simplex Tour de France rear derailleur works perfectly out on the road, with accuracy, and no trimming.  Of course, there are only 3 gears here.  And what big gears they are, ranging from 54 to 75 gear inches.  I have to wonder about these giant gears on older machines that I encounter.  Were people stronger then?  Did they simply walk up the hills?  Is France totally flat?  Ha.  I can lower the gearing a bit by going up to 24 teeth, which is the maximum that this derailleur can handle.  Or maybe I’ll just tough it out for now.

Simplex Tour de France

It is very difficult to find builder information for bikes manufactured in France during the occupation years.  Based on some reading, I have learned that the cycling industry in France actually experienced a “bike boom” because petrol was unavailable to the populace, so driving was no longer really an option for most people.  And, there is a lot of shame surrounding those businesses who benefited financially during those terrible times, even though they may have been among the resistance on a moral and intellectual level.  The disruptions to normal business practices during the Nazi occupation, as well as this shame and possibly the need for secrecy has meant that it is nearly impossible to determine what exactly was going on in some of the cycling shops in France during the time.  I have found it interesting that there were sudden innovations (Simplex derailleurs) and new companies emerging (Mafac) right after France was liberated.  I suspect that research and innovation was in fact occurring during the occupation years, but went on, undocumented.  (Jan Heine has an interesting blog post about this topic here.)

Correctly dating this Peugeot has been challenging.  Peugeot catalogs during the late 30’s and 1940’s cannot be found.  There is very little information about what was happening at the Peugeot factory during the occupation, with the implication that they actually shut down.  Some websites claim that the factory did shut down during the occupation, but I think they may be referencing only the automobile factory, as by this time the bicycle factory had been separated out as a distinct division, located in Beaulieu (Mandeure), France.  So, my best guess based on its original components and on the frame characteristics is that this bike dates to sometime in the late 30’s through the 1940’s.

I was worried that the wood grips, which are very comfortable, would fly off the handlebars during vigorous climbing, as they are connected to the bar only with a conical cork insert located inside the grips, which I tapped into the bars with a mallet.  They held fine.  The Gauthier ladies leather saddle was shockingly comfortable – no changes were needed there.  I was also concerned that while the brake levers are quite lovely, the shape would inhibit emergency braking, with their slight arc in the middle restricting the movement.  As it turned out, braking was quite noisy!  This alerted others to my presence.  I had installed Kool Stop orange pads on the front, but had left the old funky Mafac pads as is on the rear.  Big mistake!  This bike needs Kool Stops front and rear, plus a complete cleaning and sanding of the rims to eliminate braking squeal, which I have now done.

Thank you to Shawn at Adventurepdx, for this nice old Carradice bag which goes perfectly on this Peugeot.  I don’t use saddlebags much, and was shocked just how much you can jam into this thing.  It is the perfect addition to the bike and adds all the utility needed to make this a useful commuter and weekend rider.
