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 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

Trek Madone SL 5 Pro Road Bike in Gloss Dark Star/Matte Deep Smoke

Season:2027

Brand:Trek

Code:92145BLK

The Trek Madone SL 5 Pro Gen 8 is a lightweight aero road bike that brings elite racing technology to a more approachable price point.

Full System Foil tube shaping and 500 Series OCLV Carbon construction save weight where it matters most, while IsoFlow comfort tech lets you ride stronger for longer without sacrificing aerodynamics. Shimano 105 delivers clean, reliable mechanical shifting, and Aeolus Elite 48 carbon wheels help keep the ride fast, efficient, and ready to race. Trek's lightest Madone SL Disc ever uses light-yet-economical 500 Series OCLV Carbon, making it an ideal climbing bike. Revolutionary Full System Foil aero tube shapes improve airflow over the whole bike while maintaining the lightness that climbers crave. The bike’s entire rider system was meticulously designed and rigorously tested to be faster everywhere.

Trek refined its race-focused comfort tech to be lighter and have nearly double the vertical compliance so you can ride stronger for longer. The Madone SL was informed by feedback from Lidl-Trek's fastest sprinters and climbers. The Madone Gen 8 features an adjustable aero cockpit with hoods that are narrower than the drops, allowing you to adjust your positioning to prioritise aerodynamics or power. The two-piece design lets you quickly and easily dial in your fit.
