With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.
Your Pre-Order is prioritized (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or dispatch to you — it often never even hits the stock room shelves!
With Prelaunch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Preorders.
So, instead, you can submit your email address for the item you are interested in, and we will email you as soon as stock arrives in the system.
Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indicative purposes only and can change at any time without notice.
The dates we provide are based on information given by our suppliers. Whenever we get updated information from our suppliers we will endeavor to update the Estimated Delivery & Collection Dates provided on product pages.
Season:2024
Brand:Shimano
Code:ICSR910011128
Upgrade your gearing to the incredible dependability and meticulous engineering of Shimano's Dura-Ace CS-R9100 11-Speed Cassette. 9100 isn't a typo there, it is, in fact, a newly reworked version of Dura-Ace. When the brand introduces a new groupset, you can be sure it's actually boasting improvements you don't have to be in the pro peloton to immediately detect.
Since Dura-Ace is the top-tier drivetrain in the Shimano road lineup, you might be surprised that only the largest five cogs are titanium. That's because—though it's lighter—titanium is generally more prone to wear than nickel-plated steel, and the smaller cogs are more prone to wear than the larger. Because of these material properties, Shimano only uses titanium where the softer metal doesn't create a significant negative impact.
