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.
Mafac tandem twin brake lever
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.

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.

B&M, Busch und Müller EYC, fender mount, Gilles Berthoud 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.

Routens tandem

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.

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.

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.

Time trial Hamburg - Berlin*

*Curslack - Spandau to be precise - 14.10.2017

Organizers website: HHB 2017
On the Velomobile forum: HHB 2017

The solo and team time trial Hamburg - Berlin is the seasons closing event of the Audax Club Schleswig Holstein. An inspiring mixture between brevet and race.  Its long enough to get brevet riders like myself interested, yet short enough to attract the fast racing crowd and triathletes. The course profile lets recumbents and faired HPVs play out their strength, and the fierce but friendly competition among them makes it feel like their informal championship. Accordingly there was a selection of the finest human powered vehicles on display, ranging from classic randonneur bicycles to the latest velomobiles. For my part, I rode the Pass Hunter. (VO Pass Hunter build). 

Powered by nature.
S21 to Bergedorf. "Powered by Nature"
one of the few rules for the time trial
Hamburg - Berlin.
The rules are pretty simple and leave a free choice of itinerary, as long the propulsion is human powered, traffic rules are respected, and two bridges over the river Elbe are crossed exactly once in the correct direction. 

Velomobiles
There was a selection of the fines human powered vehicles on
display at the start.
The event is characterized by a mixture of nice touches on one side, and professionalism in its complex organization, that is executed entirely by the Audax Club SH on the other side.
Quattrovelo
Quattrovelo.
The inscription is literally worth the money, as it includes a generous breakfast buffet at the start in the Curslacker Landhaus, food, coffee and water at the only control in Dömitz, and luggage transport to the finish, where cheap beer, barbecue, and more excellent food wait to celebrate the days adventure.
Time trial bike.

The landscape along the Elbe has some marvelous stretches, and this year it was possible to actually enjoy it. Hamburg Berlin has a certain reputation for its autumnal weather, but this edition was the exception confirming the rule: The weather was dry, warm, and a steady tailwind procured a feeling of  smooth sailing. A welcome change after last years laborious ploughing into a consequent headwind accompanied by light rain.
Elbuferstrasse
On the road on the first leg. Mainly 'Elbuferstrasse'.
I had a late start at 7h44, and was quickly passed by a number of velomobiles, even though most of them had certainly chosen the latest possible starting times approaching 9h. No surprise, as the fastest hold average speeds around 50 km/h against which my 29 km/h for the first 95 km to the control in Dömitz are ridiculous at best.
Human powered vehicle

After mainly following the Elbuferstrasse, unsure whether the damage of Sturm 'Xavier' the week past had been cleaned up, I headed up the first hill in Alt Garge where I had cut through the forest last time.

had cut through the forest last time (red).
And who wouldn't invest a few hundred additional meters and a little climbing to take advantage of the only real switchback in 285 km?

Approaching Damnatz I decided in favor of the seemingly shorter zigzag through a maze of fields and farms where I had followed the meander of the Elbe last time.

After 3 h of comfortable riding with comparatively little effort, the second mandatory passage south to north over the bridge in Dömitz appeared in sight.
The organizers provided some food and water at the control.
(There even was a surprise feed station on top of one of the
hills close to Hitzacker).

Control.
Velomobiles at the control - for some the only stop.
Being a slow rider, I spent just a few minutes at the control to refill my water bottles, and enjoyed a short coffee and half a banana. Its a single stage event, the clock is always ticking, and it pays to be efficient in average.
Small villages ...

... linked by scenic backroads without traffic.

Most went without any luggage.
After some time I catched up with the well equipped race tandem, that had left the control just when I arrived, and wondered how our weathered vintage Peugeot TM8 that spends the weekend in the shed would fair on this course.
Say hello to the tandem.

I found the way to the dike, that I had missed last time, unsure whether the gravel route continues, and after I had seen other riders decide against. Its one of the beautifully desolate places, and the gravel path on top of the dike was fast rolling in the dry conditions.

Many riders follow a route close to the Elbe for quite some time.

They were much faster, but had a different (longer) route and
longer stops.
I had been passed by many fast riders in the first leg, and to my initial surprise quite some of them now overtook me once again, a few even more than twice I believe, but its hard to distinguish riders with identical jerseys form clubs participating with several teams. They were already greeting me as 'le randonneur' for my conspicuous steel bike, front luggage, leather shoes, and unshaved legs.
Wittenberge, half way out.
Wittenberge - about half-way out.

I was passed by many riders.
Yet it shows, how different equipment-, route-choices and stop strategies can partially even out on a long event. Speaking of strategies, I have to admit, that I didn't have any this time and therefore rode a two stop strategy. I was hoping to find a gas station along the route in Havelberg, and got a little nervous heading into the rather deserted Havelland with little water left in the bottles after none had materialized. The Aldi in Friesack was still a long way to go. Just when I was about to run dry, the NP in Rhinow came to my rescue and  I refueled with  bottle of water, a coke, and a pack of 'Marzipankartoffeln'.
There was a lot going on on 'the course' and at the side of the
road. This handsome gentleman from Stendal happened to have
a track pump in his trunk, right when two participants had need
for it. He kindly took care of the inner tube no longer fit for the
purpose too. Honi soit qui mal y pense.
There were things going on at the side of the road. Cars at cycling speed, following roads that make more sense for participants but not so much for somebody providing support only at the control. May be all of them were vehicles of the organizers? Honi soit qui mal y pense. The organizers seem to have made similar observations...
Beautiful alleys
The Havelland is full of beautiful alleys.
Just on the last stretch, when I already thought I had made it,  a roadsign unambiguously told me that I wouldn't cross the Havelkanal right here because of construction work. I followed the deviation, only to realize it might use the highway.  I turned around a second time laboriously rerouting myself with the tiny screen of my GPS.
Course details.
In Paulinenaue it payed not to follow (blue) the concret slab
farm track, I considered shorter last year (red). I seem to
have been the only one not up-to-date that the bridge over the
Havelkanal was closed. Detour.

After a number of Berlin's traffic lights wearing my patience, I finally reached the Wassersportheim Gatow after 10h33 in the rapidly fading light of a beautiful day.

(Some 'real ones' ride back...)
This edition saw the introduction of a 'starters pass' (not
shown), QR-codes to scan start, passage at the control,
and finish, and a finishers medal. This mixture of nice touches
and professionalism characterized the entire event.

Course
Ok, here are the numbers: A total of 285.82 km (including a small detour via
Brieselang - I was probably the only participant not up to date that bridge over
the Havelkanal was closed) in 10h33. This results in an average of 27 km/h,
stops included. As this year's conditions were perfect with a steady tailwind,
this is almost a bit shabby compared to last year's 11h29 into a consequent
headwind.
