The bottom bracket spindle end tapered down further than ISO which could cause some problems. That said, I have a couple Avocet cranks here that work fine on ISO spindles. Ofmega/Avocet cranks were nominally 144mm BCD, although the touring cranks sold under the Avocet name were also drilled for 102mm BCD and 74mm BCD inner rings, which mounted to the arms using stand-off bolts.
Ofmega/Avocet also marketed an affordable 41T 144mm BCD chainring and their crank arms were machined to provide the proper chain clearance for these rings.

What length/offset of ISO BBs are you using successfully on these cranks (double and triple)? I've got my pencil handy to write it down for future reference.
The 102 BCD annoyed me, but the 74 is great!

So, will I make big bucks when I sell my black "plastic" rear derailleur ?

The ofmega master components that came on my bianchi were terrible. The modolo brakes were icing on the cake. Look and feel of high end parts, functionality of low end parts. Presumably mistral is better though.

Ofmega mistral (esp. in pink) just looks so awesome on an over the top italian bike. Only to be ridden in a jersey that wouldn't look out of place in the Village People with yellow Briko's.

check out this Affinity 212 frame with custom drillium parts. Cicli Devotion (the builder) used Ofmega Mistral front and rear derailleurs on it:

Actually, it would have been nice if Ofmega made their plastic derailleur in a metal (Aluminum or titanium version) version using the exact same design, anodized in different colors,
I really like the way it looks, specially the black one. I might still get a black plastic version one day just to try it out on my "plastic" Vitus Carbone bike as it will look perfect for it aesthetically, catching the silver and black details on my bike's frame.....

Are those ball bearings in those jockey wheels??.......
Some do complain of stiff shifting with these derailleurs but some don't seem to mind at all........
I heard they make latex rain covers for these derailleurs too.......
DD does not have to work on these, they are already pierced with all sort of metal......
The black version seems to have longer pivot arms......bigger jockey wheels and longer cages.....
If it continues to shift for longer than 4 hours, call your bike mechanic asap!!...

That is certainly making me feel better about the brand...

Nice aero style clipped pedals. I have been considering buying an NOS set from eBay lately. I still remember drooling over those in the 80's, but I could not afford them back then.
How do they hold up? I'm asking because my brother bought Ofmega's CX quill pedals back in the 80's and unfortunately, they were terrible and just kind of fell apart on him. I remember him taking off the black plastic bearing cover caps (exactly like you have on those pedals) to service them and we could not get them to stay on after reinstalling them, no matter what we did. He ended up losing both of them wihich resulted in his outoard bearings and races wwearing out prematurely because dirt got into them all the time.

Ofmega did provide a distinctive looking crankset with their Mistral gruppo:
The crank was one of the first ones to be made that played around with the shape of the forged crank spider arm shapes. It's pretty much the gem of that group which had a sort of weird mix of things in it, including the sometimes questioned "plastic" rear derailleur.....It might have helped if they did not bother making them in pink, but I guess Miami Vice told everyone that pastels and pinks can be manly too!
Forgot to add,....I like this crank except for the overdone curly script they decided to put on it..... What's with that??! Looks like someone got carried away in the marketing department....

I don't know how they hold up over time and use. I bought them to complete the original configuration of the Equipe. I ride the bike regularly but with different pedals.

Avocet marketed them as their "Model III" pedal; Ofmega marketed them as their "Sintesi" pedal.

I recently figured out who made the seatposts. It was an Italian supplier named STM (not to be confused with ITM). It's their 'Super Competition' model, unchanged except for the logo.
