Mein Fang des Tages

[derManuel]

Dei Pedale waren parallel für C-Record und Croce d'Aune geführt.
In den Katalogen sind bei C-Record die Käfigplatten schwarz. Aber so hab ich die noch nie gesehn.

Der rückwärtige Steg für die Schuhplatten ist bei den Croce d'Aune Pedalen vernietet und bei Record verschraubt. Edit: siehe entsprechende Katalogseite.

Dann sind es also Croce Pedale, danke !

Ich habe auch noch nie Record ohne Kappe außen gesehen. Die Croce sahen für mich schöner aus. Genau, wie die Kurbel. Beim Schaltwerk finde ich aber Record schöner, genau, wie bei den Deltas und den Naben und der Stütze. Beim Steuersatz bin ich emotionslos, da sehe ich kaum einen Unterschied. Bremsgriffe und Schalthebel waren ja eh identisch.

Ich habe auch noch nie Record ohne Kappe außen gesehen. Die Croce sahen für mich schöner aus. Genau, wie die Kurbel. Beim Schaltwerk finde ich aber Record schöner, genau, wie bei den Deltas und den Naben und der Stütze. Beim Steuersatz bin ich emotionslos, da sehe ich kaum einen Unterschied. Bremsgriffe und Schalthebel waren ja eh identisch.

Optisch gefällt mir das Record Schaltwerk ebenfalls besser. Mit dem Croce d' Aune Schaltwerk, dessen Konstruktion ich interessant finde, versuchte Campagnolo die Performance ihrer Indexschaltung zu steigern.

Hier ein Auszug des damaligen Tests der Gruppe:
"While the crankset is probably the handsomest piece in the Croce d'Aune group, the rear derailleur easily draws the most stares. Attention centers on the steel linkage rod, which looks to some like an afterthought, and to others an ungainly brace appended to the sleek aluminum castings that make up the derailleur body. One editor likened the rod to external pushrods found on some old British motorcycles before such items migrated inside the engine. Sipay chuckles over that analogy, but insists it's not apt. "The rod is not a step backwards, but a real advancement in technology," he insists. Sipay explains that the rod does for the Croce derailleur what a spring does in most Japanese derailleurs: it makes the derailleur track the freewheel cogs in a precise manner. In other words, as the shift cable tugs at the derailleur body, the rod prods the main body along a calculated path.
The actual mechanics of the Croce derailleur are fairly complex. The derailleur body swings through a compound angle, moving in and out as well as pivoting fore and aft as it works its way down the freewheel cluster (all other derailleurs, even Japan's excellent dropped parallelogram units, move through only one angle). This dual motion, accomplished by an internal spring working in concert with the push rod, keeps the jockey cage close and equidistant to all cogs, which is important for indexed shifting. And since the rod cannot lose tension, there is no likelihood that shifting performance will deteriorate with age, says Sipay. In contrast, the bodies of Campy's traditional units, and that includes the C-Record derailleur, remain essentially vertical as they move throughout their range, so the distance between the freewheel cogs and jockey cage is not as tightly controlled.
Sipay also mentions a curious fact: The Croce derailleur is conceptually more like the C-Record derailleur than a dropped parallelogram design. The C-Record derailleur is not noted for its indexed shifting performance, but a dropped parallelogram design is, which is why Campa- gnolo essentially copied that Japanese design in its Chorus derailleur. The company took quite a bit of heat for that act; apparently, Campagnolo is attempting to show with the Croce derailleur that it can get good indexed shifting performance out of a derailleur faithful to its traditional designs.
Campagnolo succeeded on that score. The Croce derailleur shifted very well for me in both regular and indexed modes, rivaling the Chorus derailleur in performance. I mated the derailleur with a Regina America freewheel, a Sedis chain, and used Syncro 2, an updated version of Campy's Syncro indexing shift lever. Syncro 2 is mechanically much simpler than Syncro 1, having only three internal parts to drop on the floor and lose compared to the older version's nine parts. In terms of performance, the two are similar: Both require a bit of overshift in the lever, just as Campy's derailleurs always have. Campagnolo programmed overshift into the lever to give the rider the feel of shift- ing even though he is really only prodding the lever into the next detent.
However, neither Croce nor Chorus is quite up to the best derailleurs when used in the indexed mode. The problem is not in how the Campy derailleurs execute shifts they can get the job done as well as any derailleur made-but in their repeatability. The best Japanese derailleurs are utterly foolproof during hurried in- dexed shifting and double shifts, whereas the Campagnolo units can trip up and skip cogs or grind the chain if you get a little frantic at the lever. I suspect this is because Campagnolo does not specify or include its own freewheel for Syncro use, and no other freewheel currently made exactly matches the spacing of Syncro's indexed stops."

Ich weiß, technisch interessant finde ich es auf jeden Fall. Deswegen, hätte ich mal (fast) unbegrenzt Platz und Geld, würde auch ein Specialissima Croce hier Einzug halten.
