Mumbai, India – more traffic than you could shake a stick at

I was in Mumbai yesterday. 


Now there’s a city I wouldn’t dare cycle in, though some brave souls do. 

Given the traffic is so heavy and slow, the commute time by bike is probably equivalent to that by bus or car. 

Life expectancy would be significantly shorter though…

This man deserves a medal. Or even better, a helmet and some lights!

Velobrico Workshop: 1999 Colnago Tecnos Soft Paint

After looking for a number of years, an opportunity presented itself and… I just bought my first Italian bike!

Here’s the photos from the advert, mostly looking complete and in sound condition. 

The Tecnos is a steel framed road bike, made by Colnago in the second half of the 1990s and I understand to be the lightest steel frame they ever built. The tubing is made by Columbus, with a special alloy, made only for this bike. 

I presume this was one of the last frames to be made in Italy before work was outsourced to the far east. The frame is painted in Colnago’s Art Decor style, a somewhat psychedelic, vivid paint scheme, done entirely by hand. It’s really something special. 

On getting it home, for once I managed to contain my excitement and took some close-up photos before I did anything to it, though I was itching to get to work!

Non-original saddle. 

The bell really adds to the look, and the reflective tape on the head tube. 

A little cable housing rub on the head tube. 

Damaged chrome on one fork leg, not good.

Rims are sound and true, no cracks. 

Really nice lug work. 

Lovely brakes. 

The other fork is fine. 

Some pretty spectacular paintwork. You either love it or you hate it!

The paint was a surprise. I expected it to be glossy, but it’s actually a matt, soft, slightly tacky finish. Quite unusual and I have never seen this before. 

Chain rings are good, no shark teeth. 

Quick release put in the wrong way round. 


Cleats that don’t work with my cycling shoes. 

I spent the rest of the day washing it, removing stickers, the bell, the saddle bag, the lock, and various bits of sticky tape. 


…and servicing the gritty and grimy rear derailleur, cleaning the chain, adjusting the saddle, brakes, installing some new Michelin Classic tires and switching out the pedals to Ultegra SPDs for a test ride. 


Some blue grease, to go with the blue frame šŸ˜. 

As there’s still some more to do, I’ll keep the photos for another day, but I took it for a shakedown ride on Sunday and it greatly exceeded expectations. 

My overwhelming first impression was how smooth it is. Very little road vibration, smooth shifting, everything is tight. At speed it just flies with very little effort. Gearing ratios are little odd, and didn’t give us much range as I would’ve expected for a triple chainring, though climbing was no problem. Steering is very precise, without being twitchy and nervous. I had never ridden Campagnolo before, so the shifting took a little getting used to, but it has a good, positive, clicky feel.

It’s amazing how well this 18 year old bike rides, a real cracker.

Watch this space for updates and photos of the finished project!

Oh yeah

Finally the wait is over. I bought my first Italian bike. 

And what a bike! 

Can’t wait to pick it up…

Tandems

I thought tandems were pretty straightforward.

Then I saw these!

Velobrico Tinkering: Dynamo lights

Though I have absolutely no experience with dynamos, nor any real idea how they work, last Sunday I decided to tackle the non-functioning rear light from the Tigra ladies’ bike.

This bike has a dynamo installed, even though it is not such an old machine. I was recently told that in Germany it is illegal to ride a bike with battery powered lights. I’m not sure if that is true, (German cycling laws here…) as it does sound pretty nonsensical, though I’m pretty certain you are allowed to ride in Switzerland with whatever lights you want.

Once I figured out how to engage the dynamo so it would work from tyre rotation (this seriously took me a few days of prodding and pulling to figure out), the front light functioned fine but the rear refused to shine.

img_3041

First, I removed the plastic housing and checked the bulb. Filament looked ok. Checked continuity with the multi-meter, all good. Screwed it back in. Crossed my fingers. Nothing.

img_3053

Then I had a look at the wiring. The dynamo has two wires coming out of it, one for the front light, another for the rear. Not sure how this can make a complete circuit, but I guess that’s not necessary for DC power. The bulb socket seems to be connected to the mudguard itself, so presumably being grounded is sufficient for a DC circuit. My lack of electrical knowledge is by now apparent.

The wire hanging out of the bottom of the dynamo seemed loosely connected, but I noticed a spring-loaded connector in the bottom which holds it in place just fine. The wires head into the rear mudguard, then follow a crimp in the side until exiting through a hole in the rear, into the light fitting. This wire is then connected to another metal clip, basically wedged into a bent flap, held in place only by the “springy-ness” of the metal itself…

The wire going into the rear light fitting looked a bit corroded, so I took it out, sprayed some white vinegar on it (helpful for oxidation), dried it, rubbed it with some steel wool. The copper colour shone nicely, so I “re-twizzled” the strands, rubbed the metal clip with the steel wool and reinserted the wire. Crossed my fingers. Tested it it again. Nothing.

Then I removed the bulb and filed a tiny bit off the bottom to ensure good contact. No joy.

I now removed the wires from the dynamo and did the vinegar, steel wool and “twizzling”. Crossed fingers. Tested again. Nothing.

img_3062

Not to be deterred, I removed the bulb again, and found bits of spider eggs or some other insect leftovers. Blew those out. Another round of vinegar, steel wool, scraped a bit with a screwdriver, dried it, sprayed a bit of WD40 on it.

img_3065img_3066

While I was at it, I sprayed a bit of WD40 on the metal clip and the wires at the dynamo. A bit of WD40 often works wonders.

Screwed the bulb back in. Crossed my fingers. And it worked!

A well earned cup of tea followed. If only every Sunday were so productive!

Velobrico Workshop: Tigra ladies’ bike

Another stray joined the workshop recently. 

Actually, as you can tell from the photos, this was a while back, when there was still sunshine and no snow!

Tigra is a historic Swiss manufacturer (I understand they disappeared in 2001, bought by Villger, another Swiss brand), which adds another local bicycle to my collection.

This one was left by the bins with flat tires, lots of cobwebs and wrongly adjusted this and that. Nothing major missing though (like saddle, wheels, pedals, handlebars etc.), so all it needs is a little TLC.

I love the frame colour. It’s a really electric blue-green aquamarine which almost looks cromovelato. Really nice. The pictures here don’t do it justice.

The lugged steel mixte frame has the usual mistreatment scratches, but from being badly stored rather than well ridden. The “Tigra” decal from the down tube has disappeared, but the lettering is faintly visible.

I haven’t done any research, but judging from the components I would say this is an early 90s bike. STI shifters. Shimano STX hubs, no-name aero rims. The pedals seem to have been replaced relatively recently (these are the Decathlon urban flat variety, cheap but decent pedals).

Gear shifters and brake levers were oddly inverted, which must have made braking tricky. Gears didn’t shift correctly (WD40 sorted that). One tire pumped up fine, the other needed a patch. One wheel needed a bit of truing, but nothing major. Re-greased the hubs and gave it a wash (after taking the “before” photos for once!)

With very little effort, this middle-aged lady is back on her feet. I bet she’s glad I rescued her!
