Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (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 despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

Cube Aerium C:68X SLT Triathlon Bike in Liquid Blue Grid/Chrome

Season:2027

Brand:Cube

Code:1138700BLU

Developed in collaboration with World Champion Lucy Charles-Barclay, the Aerium C:68X is the fastest frame Cube has ever made.

Every detail, from the aero fork design and disc brake integration to in-frame hydration and storage systems, has been designed with zero compromise. Tested in the wind tunnel and under pressure in race conditions, the frame features a high-rise bar for medium and large sizes.

The Aerium C:68X SLT features premium C:68X® carbon construction with flexible, adaptable hydration and storage options, including the ability to add up to two hydration systems for longer races. The Cube cockpit offers a wide range of adjustment, putting everything you need at your fingertips.

A Newmen Streem Aero 80/80 Vonoa wheelset, paired with Continental Grand Prix 5000 TT tyres, provides an aero match for the wind tunnel-tested frame. Shimano's Dura-Ace Di2 groupset, featuring 2x12 gearing, a 4iiii power meter, and hydraulic disc brakes, delivers precise shifts and controlled braking. A cover is included for the front derailleur mounting area if you choose to revert to 1x gearing.

Features:

  • Premium C:68X® carbon construction
  • Integrated hydration and storage systems
  • Newmen Streem Aero 80/80 Vonoa wheelset with Continental Grand Prix 5000 TT tyres
