Product Description

Five different cassette configurations are available for the new CS-R9100 component, 11-25t / 11-28t / 11-30t / 12-25t / 12-28t. Once again, details are scarce on this component but the supplied images appear to show a construction similar to that of the cassette from Shimano's XTR's M9000 group, which uses a carbon spider and a mixture of alloy, steel and titanium cogs.Features : Rider tuned gearing Wider gear combination: 11-28T/12-28T/11-30T (new gear combination) Closer gear combination: 11-25T/12-25T Lightweight CFRP & Alloy spider arm, 5 titanium sprockets Gear combination: 11-25T, 11-28T, 11-30T (New gear combination), 12-25T, 12-28T Weight : 175 g in 11/25Range : 11-12-13-14-15-16-17-19-21-23-25 11-12-13-14-15-17-19-21-23-25-28 11-12-13-14-15-17-19-21-24-27-30 12-13-14-15-16-17-18-19-21-23-25 12-13-14-15-16-17-19-21-23-25-28#shortcode_video .row { display:block; }#shortcode_video .col { padding:15px; }
