Here is a quote from a frame builder regarding shaping of blades to fit specific crown shapes: "I reshaped some Prestige blades to fit a different, Japanese-made aero crown, which was actually closer to a real airfoil in that it had a sharper crease down the back. The Col. Air blades should be...

As with your forks, I would have expected the fork decals in the example provided would have had "AIR" decals (looks like those blade decals are original on Peter's bike); your fork appears to be the same design. Those decals are typical for "SL" /"SP" blade designation. (early pre c.'88 version).

I got this photo forwarded to me from a friend who states that it is the crown from a boxed set of "AIR" lugs and tubes. He was told that Columbus did not make the crowns themselves, but they were IC crowns made (contracted) to fit the particular shape of the "AIR" fork blades. Pretty obvious...

They had the lockring (w/tab) and a spacer (no tab). I would have to look at my bike to see what it has for markings; I think my gruppo is c.'74. Not uncommon to find Campagnolo stuff out there that was not found in catalogs.

Speaking of Bernard Carré bikes: late '70s "Type Competition" (per head badge); Super Vitus 971 frame. I do not think it is a racing frame for its era due to ~43cm chainstays which would be fairly long for any racing geometry. Notice rear wheel space even with hub about as far forward as it can...

@AJ 1967 No problem. You have enlightened (and interested) me regarding "newer" Olmos as my present model is substantially older (and also hard to ID), and before they started using more of the various Columbus tubesets on the market in the early to mid '80s and beyond. I am somewhat perplexed...

Again, not disagreeing with your assessment. I am certainly aware of framesets not using a full "type" ("SL" or otherwise) set of tubes. A full "SL" frameset (frame and fork) would have the helical ridges. Many builders would use a completely different fork (no Columbus components), and/or a...

All the Columbus top end tubes of the era that were CrMo ended up being termed "Cyclex" (a patented name, sometime in the mid '80s); later tubes with the same model names (e.g. "SL", "CROMOR", et al.) were made from a new CrMo alloy called "Omnicrom" (I think fairly recently c.2020), "Nivacrom"...

@AJ 1967 here is an "SL" chart I have, not sure of the year; but it is that general period given the single wing dove logo and spec'd weight. I would certainly check the steerer tube for the reinforcement ridges. I think that would tell you that it is "Air/SL" since the "CROMOR" steerer did not...

@TomBag Yes, definitely not an "Olympic" bicycle. Hero has been around for decades ('50s), that bike looks mid '70s "bike boom" style ("safety" brake levers, stem mounted shifters). Not quite the same level of quailty as the Olympic brand (that bike's model is Olympic Spirit), and I doubt the...

Same 25nm as ALAN frames.

I praise @bobby-gg for not voting for himself like most politicians would have done. I would be quite pleased if that "no votes" bike showed up gift wrapped on my doorstep even (though a wee bit large for my size).

Fine win for a very fine trike! Might be my first time going for the winner. Again, all were great entries and I would enjoy taking any of them out for a few days of fun and adventure.

@AJ 1967 thanks for the comparisons. Unfortunately, I do not have an Olmo of that vintage; mine is c. 1978-'80. It is very difficult to judge by weight given that your frame is on the smaller side for sizing. I am pretty certain that the weights referenced were for a larger frame size (56cm?)...

See my previous comment about "AIR" seat tubes. 2 designs were used.

@AJ 1967 Here is what a full "Air" tubeset would be initially: teardrop shaped DT, ST, & S-Stays; oval shaped TT & C-Stays; round HT. Later it had teardrop shaped C-Stays. Also, the seat tube had 2 configurations: teardrop shape to the top requiring the same teardrop shaped seat post, and a...

Great showing folks. Easy pick for me, even though all are great! I will have one to enter next year if I am blessed enough to still be cycling in this "mortal coil".

Funny, but I thought "musette" was a reference to bagpipes and was thinking that those bags were missing their pipes! It must be a UK thing.

I know if I had any say, and without knowing what their product range was before (aside from frames) that they should market branded clothing, kits, accessories, etc. As someone who owns many older model bikes and which I probably have no intent of purchasing a brand new frame/bike at this stage...

You can wish in one hand and $#it in the other and see which ones fills up first. Here's to wishing things go well!
