The heat of the day rose faster than we could climb
to reach cooler elevations. Thanks to the many
water points along the route two large bottles were
sufficient for the two of us.

Tandem restoration tidbits: cable guide

One of the first things I did after taking possession of our tandems was a restoration of the cockpit areas that had been changed by the previous owners. Both, the Peugeot and the Routens came  equipped with three brake systems: two rim brakes and a rear drum brake.

Vintage tandems often come equipped with three brake
systems and the rim brakes on a twin lever.
I decided to restore them in the original configuration with the two rim brakes operated from a twin lever on one side, and the drum from a conventional lever on the other side.

would make for busy air space with all the noodles, if there was no cable

With the non-aero levers of the time, this makes for busy air space with all the 'noodles'. When looking for ideas on how to organize the cable routing I got inspired by the Specialites T.A. brake cable guide (Velobase).

I anyway had already considered to drill the stem to double as brake cable hanger and to do away with the flexy original ones mounted under the headset nut. Combining the two ideas led to the following solution:

from the hardware store was modified to a domes shape and
polished to blend into the classic ensemble.
The stem was modified with a stepped bore (at 17 degrees, so that the cable runs parallel to the head tube) to act as brake cable hanger, a M5 tapped hole for the cable guide stem plate, and another M5 tapped hole for the Crane bell.

(i) to act as front brake cable hanger, (ii) to fix the cable guide, and (iii) to
mount the bell.
To mount the cable guide to the stem, stainless steel bolts from the hardware store were modified to a domed shape and given a high polish finish to blend into the classic look of the ensemble.

As a last little detail, the two brake cable housings coming from the twin brake lever were tied with stainless steel wire, in order to keep them organized without recurring to cable ties.

Tandem restoration tidbits: headlight mount for the Peugeot TM 8


B&M, Busch und Müller EYC
Fender mounted headlight. Modern interpretation of the original.

Our Peugeot Tandem came with a replacement front fender and had lost its original fender mounted headlight in the process. And while I don't really miss the glow of a conventional bulb powered by a bottle generator from a practical point of view, I do like the esthetics of those french fender mounted lights.

Peugeot tandem TM8
Interim solution. The affordable and quite capaple Busch and Müller Eyro
took over until new fenders were purchased, a generator wheel was laced and
a suitable led light selected.
For the creative restoration I was thus looking for a modern solution uniting the original spirit with the performance of modern led lights. Besides the obvious candidates with a classical look (Edelux and IQ-XS), I liked the shape of the EYC which could be taken for a descendant of the aleady modern looking fender mounted lights of the eighties.

Peugeot tandem TM8, B&M EYC
The Busch and Müller is a little gem and fits nicely in the overall esthetics
after some modifications and with an appropriate mount.
And the realization that the upper body shell of the EYC is made from alloy and could be stripped and polished makes it a little gem in my eyes. I felt that the 'EYC' logo was looking too busy and filed it away when stripping the paint. The shell fortunately polished well and came out looking gorgeous.

Fender mount for B&M EYC
Evolution of the light mount from first draft to final shape. I wanted to create
a modern interpretation of those vintage light mounts from folded sheet metal.

What was still lacking is a light and secure mount. There is a commercial solution available from Velo Lumino (here) but I wanted to create a modern interpretation of those vintage light mounts created from folded sheet metal.

burly edge of the EYC nicely mirrors that of the Gilles Berthoud fender.

The holder is securely mounted to the Gilles Berthoud Fender with 4 mm plain alu rivets, which have a low profile on the underside and won't rattle loose. As much as I like 'french fender cuts' I left the Gilles Berthoud fender untouched as the burly edge of the light nicely mirrors that of the fender.

Front view. In the background the quite efficient Weinmann brakes.
The mounting position turns out perfect, as the light has no chance to cast busy shadows from its vantage point. The illumination of the EYC is very even, and the moderate total output compared to the top of the line models has the benefit that its easier to accommodate to dim objects in the surroundings.

Cycles Routens Tandem

Since our first tandem experience and some memorable rides in the Vercors and Chartreuse mountains with a rental from Métrovélo in Grenoble last summer we were hooked.  Already during our holiday we scoured the internet for an affordable used bike made for two. We managed to locate a nice Peugeot TM8 Ladyback in Hannover that we picked up while still on our way home.

The Peugeot needed some work to get back in shape for longer excursions, and when browsing the web to source parts and learn more about tandems in general, we came across this beautiful Routens for sale at Cycles & Go. Although we had little hope it was still available, and we didn't really need a second tandem, we dropped a mail ...

... and were lucky. After my first visit, Cycles & Go were kind enough to reserve the bike, replace some damaged components, and change the rear cassette from 14-26 to 14-28. They agreed to keep the bike for a while until we definitively could take possession of it during our next holiday in the region, and I was able to recover a few parts for restoration.

cables du frein tambour et le frein M.A.F.A.C. arrière.
We had decided, that the handlebars, seat-posts and saddles needed some adjustement for a proper fit and a bit of attention for better looks. Clear shellaced tressostar cotton bar tape, a hole in the stem for the front brake cable, T.A. style diy cable guide, and a shiny Crane bell definitely improved the overall appearance.

Routens tandem Chartreuse

Re- mounting the parts, and the first few small excursions in the foothills of Belledonne and on the plateau du Vercors confirmed both, a nice a ride, but also that a second french tandem meant opening another can of worms. That said, I have to admit that I actually do enjoy the hours spent in the workshop understanding 'french bicycle idiosyncrasies' combined with the particularities of tandem components when the weather does not allow any outside activity.

The bicycle is equipped with a range of nice french components: MAFAC brake levers, MAFAC Racer front and rear brakes mounted on braze-ons, Specialités T.A. tandem crankset, JPR pedals, Huret derailleurs, Maxi-Car tandem front hub, Maxi-Car drum brake in the rear, Mavic and Super Champion rims,  JPR handlebar, aluminum fenders, Cibié lights.

Routens tandem Vercors Moucherolle

But despite the nice looks, Routens decals, and being partially equipped with what used to be high end components - there is some nagging doubt about the frame: the presence of JPR components places the bike in the era of Jean-Paul (rather than Jo) Routens, the fork resembles a Peugeot or Motobecane tandem fork at least as well as the ones with the famous biplane crowns, and the finish of the seat stays and twin laterals reminds the bike boom tandems more than a fine custom frame. At least some of the tubes are seamed, and with close to 23 kg, the bicycle is overall a bit on the heavy side. Could it be that the frame was subcontracted, and the bike 'only' assembled by Cycles Routens?

In the end, this observation doesn't take anything away from our enjoyment, and we decided right away to take the bike on tour at the next best occasion - but this is another story.

Quand il pleut dehors nous voyageons dans les souvenirs.

Around Grenoble 'Cycles Routens' is still a household name and while tandems rarely fail to prompt cheerful comments, its even nicer to hear an "Oh! Le joli Routens ..." and to engage in a short conversation about beautiful bikes made in the region.
