1988 Campagnolo Chorus rear derailleur
As the saying goes: when you are at the top, there is only one way you can go...
I vaguely remember a time when Campagnolo was the unquestioned leader in bicycle componentry. If you were cycling in the sixties and seventies you were either a cyclist that rode Campagnolo or a wannabe that wished you were. Then came the Japanese-led innovations of the 1980s with refinements in componentry design, product integration, manufacturing methods, and mass marketing. Bicycling became more accessible to the general public and the market base exploded. People who had never heard of Campagnolo started to ride bicycles. And, God-forbid, the infidels even started to make inroads into the skeptical, technophobic, Eurocentric professional peloton.
Campagnolo responded. In 1985 they brought out the C Record group which capitalised on the company’s strengths: achingly-beautiful, over-engineered, shop-supported, high-end stuff. And despite being technologically-challenged it hit Campagnolo’s target audience by being both very expensive and highly desirable. At the same time Campagnolo also tried to compete directly with their Japanese counterparts with the introduction of two lower tier groupsets: Victory & Triomphe. Unfortunately all this did was highlight just how much better the Japanese had become.

Campagnolo Victory & Triomphe
By managing to be both aesthetically-compromised and technologically-challenged Victory & Triomphe were met with a poor reception and a swift demise (As always: Be beautiful and stupid and you will still make it in this world. Be ugly and stupid and expect ridicule and rejection).
Towards the end of 1987 Campagnolo introduced the Chorus group followed shortly by the Croce d’Aune then Athena groupsets. By the end of 1988 these three ensembles had lined up neatly beneath C Record (in descending order: C Record>Croce d’Aune>Chorus>Athena). And they didn’t just look good (following the flowing, aerodynamic lines of C Record), they also made some (grudging) attempts at modernity. In particular, Campy’s take on this new-fangled, slant-parallelogram-rear-derailleur-thing.
Ultimately, the concept was for the top jockey wheel (guide wheel) to remain as close to the rear sprockets as possible to allow for faster and more accurate shifts (faultless index shifting requires this plus a lot more and won't be discussed here). Each rear derailleur accomplished this in a different way. Athena did this with a toothed insert engaging a series of detents behind the hanger bolt. This allowed for 5 different positions of the rear derailleur depending on the size of the the freewheel. Chorus had a slant parallelogram with an adjustable body (see figure below). And Croce d’Aune managed to make this a complex maneuver with cable pull angling the derailleur body (and jockey cage) backwards as well as driving it inwards. The peculiar external rod guides the movement by angling the travel of the parallelogram along the profile of the freewheel.

Of the three concepts, I like the Campagnolo Chorus rear derailleur best. It was the first, it had the best solution (essentially attempting to improve on the Japanese idea), and it had that wonderful art deco industrial style about it. It was also the first time the Italian establishment openly copied technology developed by their upstart Japanese rivals. And boy did Campagnolo struggle with this humiliation - they persisted with an antiquated design on their top-level C Record rear derailleur (a design essentially unchanged since the 1950s) and suggested two alternative solutions with Athena and Croce d’Aune. By 1991 the entire Campagnolo range (including their short-lived offroad ensembles) had adopted the slant parallelogram rear derailleur.
For me the 1988* Chorus rear derailleur marked an important turning point for Campagnolo. It was the point that the Italian giant showed the cycling world that it recognised it had fallen behind the industrious if somewhat bland Japanese. Campagnolo ate humble pie, absorbed (ie copied) new technology into their designs and caught up.
And if none of this means anything to you, then I give you this:

Fire steering time
Ah Christmas. That special time on the Christian calender where the troll’s life in the real world gets crazy. Work becomes overloaded as people seek to redress their problems before the break. Add a smattering of late-night Christmas functions, and the daily consumption of Christmas cheer (ie chocolates, cake, finger food, alcohol +/- interesting but not necessarily coherent conversation) and life becomes somewhat messy for a preferentially solitary troll. Not that there is anything wrong with a little quiet time. Or a daily diet of microwaved broccoli. It’s just that the troll seems to need them more than the typical integrated human.
In the real world the troll employs a secretary to order him around from Monday to Friday. She’s from New Zealand. So, as a patriotic Australian, I employed her out of pity and, ultimately, to make fun of her. Just as it is my Australian duty to ridicule the Poms who still rue the bygone days of Australia as their convict colony. (irony is when a population living on a small, cold, dreary island banishes their thieves and vagabonds to a land of sand, surf and sunshine...)
Well, my secretary (let’s call her Kelly, because that’s her real name and she never visits this blogsite despite my pleas for her to increase the traffic by 100%) Well Kelly, has used the phrase “fire steering time” on a number of occasions. I never really understood this and what I can’t comprehend I simply ignore (which, according to Kelly, tends to be quite a lot). One day I made the mistake of responding - which went a little like “what the f-k? How can you steer a f-king fire?”. Returning a phrase after peppering it with expletives and combining it with a resolute lack of eye contact usually means “go away, I’m trying to ignore you” and is usually met by a caustic glare and a stomp back to her desk. But Kelly was having a good day. So she rolled her eyes (she rolls her eyes a lot), sighed (she sighs a lot) and sat down (exactly what I didn’t want, and it makes me very uncomfortable).
“I’ve told you this before but, as usual, you’ve forgotten. (did I mention she’s from New Zealand? Australians don’t need to listen to New Zealanders) Remember back in the caveman days when the man goes out all day to hunt and the cavewoman stays home all day cooking, cleaning, and looking after the baby? (yes, have things changed?) (rolls eyes) Well, anyway, she builds up all these things she needs to let out when her caveman husband returns. So when he comes back after a hard day hunting she bombards him with the trials of her day in the cave - the baby cried and was inconsolable, the seeds are spoilt, the neighbours are bitching again, your mother came round to tell me how to raise a family... To which the caveman responds by putting up his hand and says “fire steering time”. So he sits down on his rock and steers silently at the fire for about 20 minutes. After which he stands up, goes to his wife, and asks about her day. Fire steering time. That’s how me and Dan (Kelly’s partner) maintain our relationship.”
“Oh, you mean fire staring time”
“Yes, fire steering time”
Now it made sense. And surprisingly good advice. A little fire staring time to wind down after work so you can have a fresh outlook on the next series of challenges that daily life brings.

Christmas tree steering time
At this time every year, a group of cycling enthusiasts embrace the Christmas spirit with a ride to the big Christmas tree in the city. This is an inclusive group although you don’t get an invite if you are a pretentious bicycle snob. Having misplaced my invite this year (hey, Jim, you did send it didn’t you...) I present to you a photo of some great guys who have found yet another great reason to ride.
Merry Christmas.
