The Problem: Aero Helmets That Are Fast But Too Heavy to Climb In
The classic dilemma of aero cycling equipment: the helmets that are most aerodynamically effective tend to be the heaviest, and the helmets that are lightest tend to sacrifice the aero profile that makes the difference in a time trial or a fast road race. For riders who need to be fast on the flat and efficient on the climbs, this trade-off has always felt like a compromise that shouldn't have to be made.
The Wildside Ultralight Aero TT Cycling Helmet addresses that compromise directly. Built from EPS with an ultralight construction that keeps the total weight to approximately 450g, it delivers the aerodynamic profile of a time trial helmet without the weight penalty that makes climbing feel like punishment. It's the helmet for the rider who needs to be fast everywhere on the course — not just on the sections where aerodynamics dominate.
Ultralight EPS Construction: Speed Without the Weight
EPS (Expanded Polystyrene) is the material of choice for high-performance cycling helmets because of its exceptional strength-to-weight ratio. It absorbs and distributes impact energy effectively while remaining significantly lighter than alternative impact-absorbing materials. The ultralight construction of this helmet takes that inherent advantage and optimises it further, producing a helmet that provides meaningful aerodynamic benefit without the neck fatigue and climbing penalty that heavier aero helmets can introduce.
At approximately 450g, this helmet is light enough to wear comfortably on long rides and climbs, while the aero profile ensures it delivers a speed advantage on the flat and descending sections where aerodynamics matter most. It's a genuine all-rounder — a helmet that doesn't force you to choose between speed and comfort.
Fewer Than 8 Vents: Prioritising Aerodynamics
The ventilation design of this helmet prioritises aerodynamic performance over maximum cooling. With fewer than 8 vents, the helmet presents a smoother, more continuous surface to the wind than heavily ventilated alternatives — reducing the turbulence and drag that multiple large vents can create. For time trial racing and fast road riding where aerodynamics are the primary performance variable, this is the correct trade-off.
Integrated Lens: Goggle-Free Performance
The integrated lens system eliminates the aerodynamic penalty of separate goggles and the gap between helmet and eyewear that creates turbulence at race speeds. Available in multiple configurations — 1 lens, 3 lens, and no lens options — the lens system can be matched to the light conditions of your race or training environment.
Multiple Colour Options
Available in a wide range of colour combinations — including Black/Red, Black, Green/Black, Dark Green, Silver, Black/Blue, Black/White, and White/Red — the helmet can be matched to your kit, your bike, or your personal style.
Size Guide
- M: 54–57 cm head circumference
- L: 57–61 cm head circumference
Measure your head circumference at the widest point (approximately 2.5 cm above the eyebrows). If between sizes, size up for a more comfortable, secure fit during long efforts.
The Ultralight Choice for the All-Round Racer
The Wildside Ultralight Aero TT Helmet is for the rider who refuses to accept that being fast on the flat means being slow on the climbs. It's for the rider who wants the aerodynamic advantage of a TT helmet without the weight that makes every gradient feel steeper. It's for the rider who takes their performance seriously enough to choose equipment that works across the full demands of the course.
