Troy Lee Designs - D4 Carbon Frames MIPS Helmet (MTB)
Troy Lee Designs - D4 Carbon Frames MIPS Helmet (MTB)
D4 Carbon Frames MIPS Helmet is a Troy Lee Designs mountain bike helmet built for enduro and bike-park riders. The D4 platform is known for downhill-focused coverage and a locked-in feel when the terrain gets steep and fast. Carbon construction points to a lighter, more premium feel that works well for riders chasing high-end performance. The Frames look adds personality, making it a good fit for riders who care about style as much as function. The MIPS-equipped build adds another layer of confidence for riders who prioritize modern helmet technology.
It carries the kind of mountain bike fit that feels settled when speeds rise, but not so heavy or cumbersome that it becomes a distraction on the pedal back up.
Why We Like It: it fits the way a modern MTB helmet should: secure, ventilated, and ready for real terrain.
Why It’ll Work for You: For riders comparing mountain bike helmets, this one makes sense for technical trails, gravity runs, and all-day pedal missions where comfort still matters.
Variants / Options: multiple sizes and colorways available; check the selector for current stock.
Key Features:- D4 reigns king atop downhill podiums and BMX events across the globe. Available in carbon, composite and polyacrylite. Details are what makes the D4 the most coveted full-face in mountain biking. Prioritizing safety while balancing weight through premium construction and materials, D4 incorporates Mips®protection with an EPP chin bar and anatomical cheek pads with emergency release.
- Mips® C2 Rotational Impact Brain Protection System
- UD carbon fiber shell
- Three shell sizes to more accurately fit a variety of head sizes and rider ages
- Anatomical "3D” contoured cheek pads with emergency release system for EMS responders
- Removable snap-in, washable comfort liner with Coolmax® and Dri-lex® moisture-wicking materials
- Super light titanium D-rings
- 1000g
- CPSC 1203*, CE EN1078*, ASTM F1952-DH, ASTM 2032-BMX. *Varies by regional standards
