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.

The Troy Lee Designs D4 Composite Helmet is built with an aerospace shell design and materials, achieving a weight of 1050 grams without sacrificing strength. This helmet is a popular choice for downhill podiums and BMX events across the globe.

Safety is prioritised through the Mips C2 rotational impact brain protection system, which adds an additional layer of safety in the event of a fall. The design incorporates an EPP chin bar and anatomical cheek pads with emergency release for added security.

For comfort, the helmet routes cooling air through a front air intake system that flows through the polymer centre and power grid side mesh, keeping the head cooler during the ride. X-static and XT2 anti-microbial and anti-odour padding help maintain a fresh interior.
