BICYCLE HELMETS

Bicycle Helmets for MTB: Full Face, Trail & BMX Lids

A bicycle helmet is the one piece of protective equipment no rider should go without. This category at Foxracing.si gathers MTB helmets for every riding style – from light, well-ventilated half shells for trail and cross-country to certified full face helmets for downhill, enduro and bike park laps, plus lids for BMX and dirt jump. Whether you ride flowing singletrack after work or race bike park lines at the weekend, you will find a helmet with the right coverage here.

What you will find in this category

Full Face – helmets with a fixed chin bar for downhill, bike park and gravity riding, where face and jaw protection matters most.
Speedframe – the popular Fox trail half shell family, built for everyday riding with good ventilation and an adjustable fit system.
Trail – open-face helmets with extended rear coverage and a visor, ideal for all-mountain and enduro rides with long climbs.
Proframe – lightweight, heavily ventilated full face helmets for enduro riders who want chin bar protection without the weight of a DH lid.
Dropframe – open-face helmets with deep cheek and ear coverage, a half-way step between a trail helmet and a full face.
BMX / Dirt – rounded, hard-shell helmets for dirt jumps, pump tracks and skateparks.
Rampage – full face helmets built for the demands of downhill and freeride.

How to choose a bike helmet

Size and fit: measure your head circumference with a tape about 2 cm above the eyebrows and compare it with the size chart. The helmet should sit level, roughly two fingers above the brows, and stay put when you shake your head with the straps undone.
Coverage for your discipline: half shell for trail and XC, extended coverage or a chin bar for enduro, a full face for downhill and bike park.
Rotational impact protection: many modern helmets use a low-friction liner such as MIPS to help manage angled impacts.
Ventilation and weight: more and larger vents keep you cooler on climbs; lighter helmets reduce neck fatigue on long days.
Goggle and eyewear compatibility: check the visor position and goggle strap retention if you ride in goggles.
Certification: look for helmets certified to European standard EN 1078; gravity models are often tested to additional downhill standards.

Brands

The category is built around Fox and its well-known helmet lines – Speedframe, Proframe, Dropframe and Rampage – covering trail riding through to downhill. Bollé rounds out the selection with its own helmet models.

FAQ

What size bicycle helmet do I need?

Measure your head circumference in centimetres just above the eyebrows and ears, then match it to the size chart of the model you like. If you fall between two sizes, choose by feel: a correct helmet is snug all round, without pressure points.

Do I need a full face helmet for trail riding?

For classic trail and XC riding a half shell is usually enough. If you ride steep, fast bike park or enduro tracks, a full face or a lightweight ventilated full face gives you chin and face protection where crashes happen faster.

What is the difference between Proframe and Dropframe?

Proframe is a lightweight, well-ventilated full face helmet with a chin bar. Dropframe is an open-face helmet with extended cheek and ear coverage but no chin bar, for riders who want more protection than a trail lid.

When should I replace my helmet?

Replace any helmet after a significant impact, even if there is no visible damage, and whenever the shell, liner or retention system is cracked or deformed.
