The all-steel construction delivers exceptional durability and shift precision that Campagnolo is famous for. This particular ratio combination is highly sought after, offering both comfortable climbing gears and tight spacing in the high-speed range without the maintenance concerns of titanium cogs.<\/p>\n<p class=\"whitespace-pre-wrap break-words\">What sets this apart is the combination of bulletproof steel construction and intelligent gearing range. The 12-30t spread was ahead of its time, giving you proper high-end speed with the 12t cog while the 30t large sprocket provides a bailout gear that many contemporary cassettes don&#8217;t match.<\/p>\n<h2 class=\"font-600 text-xl font-bold\">Condition<\/h2>\n<p class=\"whitespace-pre-wrap break-words\">This Chorus cassette presents in excellent condition with very low miles. Our inspection reveals pristine tooth profiles, bright machining marks still clearly visible on the cog faces, and a complete set of original brass spacers &#8211; all indicating minimal use. The shift ramps and pins remain crisp, and there are no signs of chain wear or notching on any of the cogs. Every component we sell goes through our comprehensive testing protocol before being offered to fellow cyclists. As always, backed by MyBikeThing&#8217;s 30-day return policy because we stand behind what we sell.<\/p>\n<h2 class=\"font-600 text-xl font-bold\">Tech Specs<\/h2>\n<ul class=\"-mt-1 [li&gt;&amp;]:mt-2 list-disc space-y-2 pl-8\">\n<li class=\"whitespace-normal break-words\">Model: CS-401 Chorus 10-speed<\/li>\n<li class=\"whitespace-normal break-words\">Range: 12-30 teeth<\/li>\n<li class=\"whitespace-normal break-words\">Progression: 12-13-14-15-17-19-21-24-27-30<\/li>\n<li class=\"whitespace-normal break-words\">Material: Hardened steel construction throughout<\/li>\n<li class=\"whitespace-normal break-words\">Spacers: Original Campagnolo brass<\/li>\n<li class=\"whitespace-normal break-words\">Compatibility: All Campagnolo 10-speed systems<\/li>\n<li class=\"whitespace-normal break-words\">Lockring thread: 27&#215;1 standard Campagnolo<\/li>\n<li class=\"whitespace-normal break-words\">Construction: Individual machined cogs<\/li>\n<li class=\"whitespace-normal break-words\">Weight: ~280g<\/li>\n<\/ul>\n<h2 class=\"font-600 text-xl font-bold\">Workshop Wisdom<\/h2>\n<p class=\"whitespace-pre-wrap break-words\">Having worked with countless Campagnolo cassettes, we&#8217;ve developed a special appreciation for the all-steel construction of this Chorus variant. While titanium cassettes of the era got all the marketing glory, these steel cogs offer a significant practical advantage: exceptional durability under real-world conditions.<\/p>\n<p class=\"whitespace-pre-wrap break-words\">Steel cogs are far more forgiving of typical maintenance intervals and riding conditions. Where titanium cogs can develop premature notching and accelerated wear (especially if chain replacement isn&#8217;t absolutely perfect), these steel sprockets maintain their crisp shifting through years of regular use. It&#8217;s why many professional teams quietly opted for steel cassettes despite having access to &#8220;higher-end&#8221; options.<\/p>\n<p class=\"whitespace-pre-wrap break-words\">The 12-30t progression provides ideal jumps for maintaining rhythm, especially in the middle range where you spend most of your time. For many riders, the minimal weight penalty of steel (typically 40-60g) is a worthwhile trade-off for the significantly extended service life and reduced maintenance demands.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Notes from MyBikeThing The Campagnolo Chorus CS-401 12-30t cassette represents practical Italian engineering at its finest.
