2002 Mercatone Uno Time Trial frame

Hey! How goes? I'm doing ok - been a while huh?

Lest you think I've abandoned bikes for motorcycles or cars, or whatever it is people spend their time on, I'm still very much collecting. Picked up a few cool things over the last, oh, year or two since I posted anything actually bike related on here. I figure it'd be ok to show off a little.

We'll start with this frame. It's a 2002 Wilier-Triestina time trial frame, issued to Roberto Savoldi of the Mercatone Uno team. It was his last year with the team he got his start in as a stagiaire in 2000.

Not a lot of documentation on these frames. It's labeled as an Izoard, but it's not - and doesn't really match up with anything I've seen in catalogs. Custom? Likely. Built by Wilier? Maybe. It's aluminum - Easton Aero if we're to believe the label. The carbon is a wrap on the tube - Wilier did this on the actual Izoard of the same timeframe. The claims were stiffer than, more dampened than mumble mumble mumble. I suspect it was a majority marketing and aesthetics.

I suspect these frames were used the prior year by the Liquigas team - maybe even literally the same frames.

Savoldi, and if we're honest, the entire Mercatone team was largely anonymous in 2002 - they barely left a mark on the Giro, and didn't get a Tour de France invite. They'd limp on - sans Savoldi - for another year before Pantani died in 2004.

Cool tools

I'm a big proponent of the idea that the correct tool can make even the most painful job a little easier. There are certain tools that, while I suppose technically are the right tool, I rarely use. Socket wrenches are a great example - I find them to be heavy and awkward to use on a bike. That's totally not the case with thumbwheel ratchets, palm ratchets - whatever you want to call them, I've found myself using them frequently since I acquired them. The above are the ones I went with - I like the large rubberized grip, but there are all metal and gimbaled versions available.

Because there's no extension, there's no leverage - so you can't generate a ton of torque. But because you can put force parallel with the fastener, you're less likely to strip a bolt head or nut. Their diminutive size also means you can chuck one with a few frequently used sockets in a small saddlebag.

3/8" drive, 1/4" drive and a 3 piece set that also includes a 1/2" drive. If you have any, or pick some up, let me know what you think - are they as useful for you as they've proven to be for me?

Mavic's 640 Pedals

Picking a favorite Mavic component is a lot like picking which of your children is your favorite. It's unseemly, when we should be celebrating the unique beauty of all of them. But in the recesses of our minds, we all know there's one we favor just a tiny bit more. Sometimes it's rational, sometimes it's just because.

If you pushed me - and I mean really pushed me, it's possible I might admit a slight bias towards the 640 pedal, which is a little odd given that I never ride quill pedals. It's just one of those irrational loves for an unorthodox design. A design which probably isn't Mavic's at all.

The Mavic 640 is a traditionally shaped quill pedal, with a finish quality that has few rivals - with the innards to match. The more common version was intro'd in the early 80's, though a version was available in the 70's as well. Similar inside, but with a riveted (or maybe domed/hammered on, I don't know) cage.

This generation of 640 has replaceable, hard anodized cages, secured with hex head screws. They varied somewhat over the years, with slight color variations in the anodization color, and slightly different logos. I believe the one labeled 'Made In France' on the same side as the Mavic name is the older one, with the other two cages in the picture above being later.

Inside things get get interesting. After removing the the aluminum dust cap, removing the spindle nut and spindle, the inner roller bearing and a traditional sealed bearing are exposed. Roller bearing on the inside bearing surface, traditional on the outer.

If you think the 640 bears an uncanny resemblance to the Specialites TA pedal, you're not alone. While I can't find definitive proof, I think it's a given that the 640 is at least based on the TA pedal. It's possible that Mavic licensed the design, worked from forgings provided by TA, or had TA do everything - the latter two possibilities all things they're known to have done with other components and manufacturers. By all rights, the TA version is nicer - grease port in the end cap, replaceable flip tabs, curvier cage. A very elegant quill pedal - if you're in to that sort of thing.

Parts explosion for those who find themselves with 640's in need of a rebuild.

Kids, if years from now you're reading this, know that it's totally you (whoever is reading this) that is my secret favorite. I never liked that other kid.

Mavic's other flight of fancy

Besides electronic shifting, that is. The scale of this, however, was a little grander...

Apparently, around 1984, Mavic opened their Air Department. Bruno Gormand, head of Mavic and the driving force behind their innovation since the mid-60s, was, it would seem, something of a modern renaissance man, pushing Mavic beyond the earth-bound limitations of bicycles. Those limitations would return following his death in 1985, and the dissolution of the Air Department.


The top image is of the 'Airplume' plane, an open cockpit 2 seater. The 2nd image is its spec sheet. The third shows photos and specs for the 'Avid Flyer' variant Mavic made, which is simply labeled 'Avion Experimental' in the photocopied sheet I have. I haven't included the cover as the quality is fairly low - but would be happy to if requested.

Patent Searching

Patent searches are tons of fun. Here are a couple of patents I found that I wanted to share:

Online patent searches provide a wealth of information about the workings of some of our favorite equipment - as well as the innovations, successful and otherwise, that preceded them. The slight variations and changes that happened from patent submission to real world implementation (note the spring setup on the Syncro patent, for instance) are really cool. Even cooler are the abortive attempts - take for instance this patent from Campagnolo, which was issued around the same time - it seems to be a slip-proof shift lever where the hinged part sort of acts as a brake on the spring (???), the need for which was probably negated by their "success" with Syncro. WTF indeed.

The pictures are truly worth the thousands of words that comprise the patents. If you come across anything cool, leave it in a comment below.

The picture-linked patents above are for the Mavic 571 face-pawl cassette hub, the Campagnolo Delta Brake, the Campagnolo Syncro 1 shifter and the original Shimano STI shifters

Photographs Lie - The Mavic gruppo that didn't quite exist

Mavic's last hurrah in the complete gruppo market came in the early 00's. Mektronik, introduced in 1999, seems to have cowed Mavic enough that I can't imagine we'll ever see them market a complete group again. Expensive, quirky, and downright troublesome, Mavic was looking just a little too far ahead when they pushed their even more futuristic replacement for the Zap to market. As Shimano and Campagnolo have demonstrated, today the world is ready for electronic shifting. 10 years ago, not so much.

But a gruppo isn't a gruppo without a full array of components. Mektronic provided the integrated brake levers and electronic rear derailleur. Lesser known, but also present was the Mektronic front derailleur - a mechanical derailleur, a pretty significant departure from their 810/860 design to work with the narrower 9 speed drivetrains that were popular at the time. Mavic also introduced their leaf-spring R3 brake at the same time. All were available, for a price, with the brakes still available up until the last couple of years.

But what about a crank and headset?

Mavic clearly had plans to offer Mektronic as a complete group. And to do that, they would need a crank/bottom bracket, and a headset. Their 2000 catalog showed just such items.

The headset, a threaded model, would be de rigueur, with 1" threadless headsets appearing on most high end frames right around that time.

The crank looks to be ISIS. It looks familiar, but I can't put my finger on what other vendor's crank it looks like. My guess? It's an FSA crank, or one of the closely related companies in Taiwan, who was probably also the source for the brake calipers and front derailleur.

Regardless of who was going to make the crank, it seems that it never happened - or if it did, it certainly never happened in quantity. I've never seen the crank (and associated bottom bracket) or headset, other than in the catalog. Everything else was produced, though certainly not in the quantity of earlier Mavic components. If you have a crank or headset, please send me pictures!

Huge thanks to John Liu for providing me the images from the 2000 Mektronic catalog!
