<!--ProdInc[300298150]/Mall:[backcountry_US]-->Its not often that we see the not-so-high level groupset gaining technology thats skipped over throughout the pricier gruppos, but the Campagnolo Chorus 12 Cassette opts to up the gear ranges further than its siblings, showing its true work-horse capabilities through larger cassette options than the rest. It still packs in the same Ultra Shift platform as the Record and Super Record cassettes you see gracing the classics and tours with every ounce of technology trickled directly into the Chorus. The legendary cog tooth synchronization, shaping, and spacing ? theyre all here. The only difference is that Super Record incorporates six titanium cogs in their cassettes, which drop grams (44-grams to be precise), but this comes at a cost in more than one department. Firstly, the price tag jumps up a few notches, and secondly, while we covet titanium for its lightweight properties, it doesnt carry the same durability as nickle-plated steel, giving the Super Record a shorter lifespan for those who ride long, grueling miles, and occasionally shift under load. <h3>Details</h3> Campagnolos Chorus sings in 12-speeds with this lofty cassette Stiff nickle-chrome plated steel cogs provide long lasting durability Aluminum spider on six largest cogs increases stiffness Special coating and tooth profile boosts shifting precision Individual cogs utilize the same spacers for simple instillation 11-29 and 11-32t options are compatible with Record and Super Record 12-speed 11-34t option is exclusively Chorus compatible, adds extra gearing for increased versatility Item #CPGA04E <h3>Tech Specs</h3> Cog Sizes : 11 - 29t, 11 - 32t, 11 - 34t Cog Material : steel Freehub Type : ED <img src=https://www.antpop.co.kr/antMain/AntImgView?CustID=jellymom2&MallKind=US&MallID=backcountry&ProdInc=300298150&MallIDEncodeYes=0&SiteName=PostSelf width=100px height=20px>
