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.

Estimated Delivery & Collection Dates

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

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

Assos Mille GT Cycling Bib Shorts S11 Black Series

Season:2026

Brand:Assos

Code:11.10.317.18

As our core endurance model, MILLE GT is often the first touchpoint into the ASSOS world. It needs to make an impact, and it does – every ride, every day. It’s been carefully refined over the years, showcasing the iconic comfort, fit, and durability that makes ASSOS what it is, and the S11 generation pushes the envelope further. The new body textile is lighter, more durable, and has a deeper, true-black color while maintaining breathability, and the overall structure is locked into place with the addition of rollBar bib straps – technology adapted from the Racing Series.

FEATURED FABRICS
The new QUARTZ textile is a lightweight, breathable warp knit with permanent odorControl. The true-black color doesn’t turn white or become transparent while stretching during normal use, and 80% of its content is from pre-consumer recycled polyamide.

CONSTRUCTION/FIT
Our streamlined regularFit and body-contoured shaping reduce seams, eliminating friction for total comfort and easy layering.

ENGINEERING
rollBar:
A patented bracing design adapted from the Racing Series. Stabilizes the insert and locks it in place as your weight transfers while sprinting, climbing, and cornering.

PILtec Plug-In:
A lightweight, ultrabreathable textile band across the leg opening. The microdot silicone treatment is invisible from the outside but stabilizes fit and maintains grip in wet or dry conditions.

zeroPressure Waist:
A soft, highly elastic waist construction that improves comfort and hold at the waist, minus any pressure or pinching.

GT S11 Insert
Shock-Absorb Damping Mono 12: Compressive foam layers in a 12mm endurance platform. Thermoformed shaping reduces ridges and irritation.
3D Waffle: A patented, three-layer, perforated foam that increases breathability and eliminates excess weight.
goldenGate 2.0: A free-floating construction that moves with your body rather than against it. New cut-outs on the wings reduce friction throughout the pedal stroke.
Sundeck Tec: An ultrasoft panel at the front of the insert that minimizes the footprint and eliminates pressure, allowing a more streamlined fit and increasing airflow.
