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

Troy Lee Designs D4 Carbon Mips Full Face Helmet

Push Limits, Stay Protected

The Troy Lee Designs D4 Carbon Full Face MTB Helmet is the latest in the legendary Troy Lee Designs Daytona series. The D4 Carbon builds on the success of the best full-face helmets ever to be the most advanced downhill, freeride, and BMX helmet going. It is sure to continue the legend and pro success of Troy Lee Designs D3 and is the go-to for anyone seeking the very best.

The D4 Carbon helmet has a TeXtreme carbon fibre shell. The carbon has a spread tow construction that uses straighter fibres than standard carbon fibre. This results in a thinner laminate that reduces weight while achieving greater rigidness, increased strength, and improved impact tolerance.

The MIPS Brain Protection System in the D4 means the Troy Lee helmet delivers ultimate protection. MIPS is a layer in the helmet that allows the head to slide relative to the helmet. This reduces any rotational movement that would affect the brain.

A collarbone suspension system improves safety by directing pressure away from the collarbone in case of any tumbles.

As a result, The D4 has the most protective energy system Troy Lee Designs has ever given its riders. The new full-face mtb helmet is certified to CPSC 1203, CE EN1078, ASTM F1952 (DH), and ASTM 2032 (BMX) safety standards.

Top protection, badass looks, and a pedigree that no one can touch. The D4 is set to continue Troy Lee Design’s legacy for years to come.

Key Benefits:

  • TeXtreme® Spread tow carbon fibre shell
  • MIPS Brain Protection System
  • Ventilation channels and headliner promote airflow
  • Lightweight titanium D-rings and hardware
  • Collarbone suspension system
  • Break-away visor screws
  • Quick release XT2 3D cheek pads and X-static/XT2 washable liner
  • Includes TLD helmet bag
  • 1000g
