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:Core

The Shimano BR-R451 caliper brake has a 57mm reach which offers increased tire clearance up to 32mm.
These road brake calipers are compatible with STI and brake levers that are Super SLR enabled, such as Dura Ace Di2 7970, Dura Ace 7900, Ultegra Di2 6770, Ultegra 6700, 105 5700, and Tiagra 4600. The dual-pivot design realized a lightweight, compact and durable braking system. Dual-pivot caliper brakes have made considerable progress in reduction of tolerance and deflection as well as in durability. They have achieved firm and instantaneous braking response while assuring longer service life. Moreover, the brake pads have an improved durability of 100% to help enjoy high-response braking over longer periods. Use of these calipers with standard SLR enabled STI and brake levers results in a "mushy" brake response.
