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 FX Sport SL 6 Fitness Bike in Buff Beige

Season:2027

Brand:Trek

Code:78354BUFFBGE

The FX Sport SL 6 is an ultra-light and fast fitness bike. It has every performance feature of a high-end road bike, with the added benefit of flat handlebars for additional comfort and control.

A lightweight 400 Series OCLV Carbon frame, wireless electronic SRAM shifting and Bontrager carbon wheels make it the best choice for serious fitness riders with serious goals. A slightly shorter reach and taller stack put you in a more upright, balanced position for smooth power and all-day rideability.

Designed with 400 Series OCLV, the lightweight carbon frame keeps things fast and responsive, so you can accelerate quicker and handle with confidence. A 1x drivetrain means more versatility, simpler shifting and less things to go wrong. You still have a wide range of gears, but with lighter and more intuitive shifting. With SRAM Apex, you get precise shifting and confident braking for a ride that feels quick, fun, and in control.

Wide gravel tyres keep you rolling fast with added traction and control, while increased clearance lets you take on rougher terrain with ease. Mounts for a top tube bag, rack, mudguards and water bottles let you carry everything you need for day-long adventures, fast commutes and anything in between.
