Shimano's 105 group continues to lead the charge where performance to dollar value matters in its road group range and it fully benefits from the technology featured in its Ultegra and Dura-Ace components. The new R7000 group keeps this tradition alive and well and the 105 CS-R7000 Cassette is a shining example of a race-worthy cogset that the self-sponsoring racer can truly appreciate. Shift ramping and tooth profiles mirror that of its top-tier groups which provide nearly-identical shifting performance with only a slight increase in weight separating it from its pricier siblings. Weather and wear-resistant nickel plated steel cogs and an aluminum spider carrier helps boost the durability and creates plenty of stiffness for crisp shifts and it's fully compatible across all Shimano 11-speed road groups. Additionally, the cog ranges on offer are 11-28, 11-30, and 11-32 teeth which provide ideal ratios for tackling long canyon climbs and blistering descents on the other side and please note that the 11-32t needs a long cage derailleur while the other options are designed for medium length cages.
