HOW DO YOU CHOOSE THE RIGHT CYCLING HELMET?

By Anthony WalshRoadman CyclingUpdated 9 July 2026

ANSWER

Choose a cycling helmet based on three priorities: fit (it must sit level on your head without rocking, with the front edge 2-3 cm above your eyebrows), safety rating (look for MIPS or equivalent rotational impact protection), and ventilation appropriate to your riding conditions. Price above 60-80 GBP does not buy better protection — it buys lighter weight, better ventilation, and improved aerodynamics. Every helmet sold in the UK meets the same minimum impact standard (EN 1078). Fit is far more important than price.

KEY TAKEAWAYS

Every helmet sold in the UK or EU meets the same minimum safety standard (EN 1078) — a 50 GBP helmet provides the same baseline protection as a 250 GBP one.
MIPS (Multi-directional Impact Protection System) or equivalent technology (WaveCel, SPIN, Koroyd) adds rotational impact protection that the basic standard does not require. It is worth the modest premium.
Fit determines protection: a loose helmet that moves during impact provides significantly less protection than a snug one that stays in place. Try before you buy.
Replace your helmet after any significant impact and every 5 years regardless, as the EPS foam degrades over time.

WHO THIS IS FOR

IS THIS YOU?

Cyclists buying a new helmet and overwhelmed by options

You want to make a smart purchase based on what actually matters for safety rather than marketing claims, brand loyalty, or aesthetics alone.

Riders unsure whether their current helmet still offers adequate protection

Your helmet is a few years old, has been dropped or crashed in, or you are wondering whether newer technology is worth upgrading to.

THE ROADMAN VIEW

Anthony's advice on helmets is direct: do not overthink the brand and do not underspend on fit. The safety standard is the same for every helmet on the shop shelf. The difference between a 60-pound helmet and a 200-pound helmet is weight, ventilation, and aesthetics — not protection. But a 200-pound helmet that fits poorly is worse than a 60-pound helmet that fits perfectly, because a helmet only works if it stays in place during an impact.

The one technology worth paying a premium for is MIPS or an equivalent rotational impact system. Real-world crashes involve rotational forces (your head sliding and rotating on tarmac), and standard helmets are tested only for direct linear impacts. MIPS adds a low-friction layer that allows the helmet to rotate slightly relative to your head during impact, reducing rotational forces on the brain. The premium is typically 15-30 GBP and the evidence supporting it is robust.

EXPERT EVIDENCE

WHAT THE EXPERTS SAY

Virginia Tech Helmet LabIndependent helmet safety rating programme, Virginia Tech University
Our testing programme rates helmets on a 1-5 star scale based on performance in oblique impact tests that simulate real-world crashes. Helmets with rotational impact protection (MIPS, WaveCel, SPIN) consistently outperform those without. However, fit remains the single most critical factor — a well-fitting three-star helmet provides better real-world protection than a poorly fitting five-star helmet.

PRACTICAL APPLICATION

DO THIS WEEK

Measure your head and try multiple brands in-store
Measure the circumference of your head 2 cm above your eyebrows with a soft tape measure. Use this measurement to identify your size range. Then try helmets from at least 3-4 brands in-store — head shapes vary significantly (round vs oval) and the best helmet for you is the one that fits your specific head shape with minimal adjustment of the retention system.
Check fit with the two-finger and shake tests
Position the helmet level on your head with the front edge two finger-widths above your eyebrows. Tighten the retention dial until snug but not uncomfortable. Shake your head vigorously side to side and front to back — the helmet should move with your head, not independently. If it rocks or shifts, try a different size or brand.
Prioritise MIPS or equivalent rotational protection
When comparing two helmets with similar fit, choose the one with MIPS, WaveCel, SPIN, or Koroyd technology. These systems add 15-30 GBP to the price but provide meaningful protection against rotational brain injuries that the basic safety standard does not test for. Check the Virginia Tech helmet ratings for independent safety scores.

COMMON MISTAKES

WHAT CYCLISTS GET WRONG

MISTAKEWearing the helmet tilted back, exposing the forehead.
FIXA helmet worn tilted back does not protect the frontal lobe — the most common impact point in cycling crashes. The front edge should sit 2-3 cm above your eyebrows, roughly horizontal. Adjust the rear retention dial and chin strap to keep it in position.
MISTAKEBuying a helmet online without trying it on first.
FIXHead shapes and helmet shapes vary too much for online purchasing to be reliable. Try helmets in-store first, note the exact model, size, and colour, then buy online if the price is better. A helmet that does not fit your head shape is wasted money regardless of its safety rating.
MISTAKEContinuing to use a helmet after a crash impact.
FIXEPS foam compresses on impact and does not recover. A helmet that has absorbed an impact — even if it looks undamaged — provides significantly reduced protection in a second impact. Replace your helmet after any crash where your head hit the ground, no exceptions.

FAQ

FREQUENTLY ASKED QUESTIONS

How long does a cycling helmet last?

Most manufacturers recommend replacing helmets every 3-5 years due to gradual degradation of the EPS foam from UV exposure, sweat, and temperature cycling. Replace sooner if the helmet has been involved in any impact, the shell is cracked, or the foam is visibly compressed or crumbling.

Is MIPS worth the extra cost?

Yes. The premium is typically 15-30 GBP and the technology provides protection against rotational brain injuries that standard helmets do not address. Independent testing at Virginia Tech consistently shows MIPS-equipped helmets outperforming their non-MIPS equivalents in oblique impact tests. For the cost of two inner tubes, it is a worthwhile safety investment.

Are more expensive helmets safer?

Not necessarily. All helmets sold in the UK meet the same minimum safety standard (EN 1078). Premium helmets are typically lighter, better ventilated, and more aerodynamic, but the impact protection at the basic level is equivalent. Where premium helmets do differ is in the inclusion of MIPS or equivalent technology, which is increasingly standard on helmets above 70-80 GBP.
