TSG Technology Glossary

 reliable protection, perfect fit and superior comfort 






Ride with confidence

When you ride with a TSG helmet you’re protected against the inevitable. Each and every model of TSG helmet is rigorously tested in the lab and by our team riders in the field to provide ultimate safety. Learn more about our construction technologies and helmet protection here.

Hardshell construction

Hardshell helmets are constructed from ABS or PP plastic. This outer shell gets bonded to the EPS core for a two-piece construction that provides high durability and ultimate high-impact protection.

In-Mold construction

In-Mold Construction is a technique that connects the shock absorbing EPS liner directly to the polycarbonate shells to create a lightweight and strong structure. In the first step, the flat PC sheet is heated and deep-drawn over the helmet mold. Then the outline of the helmet shell and the holes are milled out. This PC shell is then placed in the helmet mold and the anchors for straps and fitting systems are placed. Then the mold will be closed, and the EPS is injected. Now the polycarbonate shell bonds with the EPS and a super light, yet extremely stable helmet is created.

MIPS protection system

MIPS® is a low friction layer inside the helmet, which allows the head to rotate relative to the helmet in an angled impact. This reduces rotational violence and potential damage to the brain.




Ride better for longer

A snug low-profile fit is key to comfort, protection and enjoying your ride. Fit is the core of our philosophy and is what makes us the best.

Snug Fit

We design our helmets differently from our competitors. We have analyzed the most diverse heads and determined a basic anatomical shape. This allows us to follow exactly the curves of the human head shape. You can see this very well when you look at a TSG helmet from the front: The sides of the helmet shell have more curvature and go clearly inwards. The outline of the TSG helmets at the sides and at the back is round and not straight down like with other helmets. With this production we achieve a so-called contact ring inside the helmet. Here the head touches the helmet all around.

We call this the TSG Snug Fit. Beside the better fit, our helmets with Snug Fit also look less bulky.

In order to lift the TSG helmet from the head, more power is needed than with competition models. This is important so that the helmet does not slip during use and above all remains in the correct position even in the event of a fall.

Low Fit

A helmet can only protect what it covers. Our Low Fit design sits low and fully protects the entire back and sides of your head without impairing field of vision or restricting movement.

Tuned Fit System

Our Tuned Fit System allows a rider to dial in their fit using different thickness pads on the interior of the helmet. Our helmets always come with two sizes of pads. Each size comes in a different color which makes it easy to determine the right pads to fit the helmet to the head. It is very important to adjust the helmet with these included pads. For example, if necessary, the slightly thicker pads can be mounted on the back of the head and the pad for the front of the head can be thinner, or vice versa.

Dial Fit System

The Dial-Fit System makes it easy to dial in a custom fit in seconds. An adjustment wheel on the back of the helmet ensures size adjustment and in­creases stability for helmets that do not have our Snug Fit. Some of our mountain bike enduro/trail helmets also come with a height-adjustable Dial Fit System.




Ride free

A real helmet should feel like your not wearing one. TSG helmets are built to deliver all-day comfort in the most demanding conditions, leaving you to think about your ride.

Air Flow Channels

Our innovative Air Flow vent system delivers optimal air circulation and reduces uncomfortable heat build-up in the helmet. The air channels have been designed to pull fresh air over and around the head while forcing stale air out.

Active Shell Venting

Channels between the EPS foam segments in our FlexTech instant fit helmets allow heat to rise and are then pulled out of the shell.

Screened Vents

Mesh protected vents block insects.

Comfort padding

Premium heat-sealed padding that is pre-formed and quick-drying: Removable and machine (hand) washable.

State-of-the-art body protection

TSG protective gear protects you against the inevitable knocks of riding hard and exceeds the most stringent international safety standards for personal protective equipment. From Hardshell to Pure Softshell, we offer constructions for all conditions and riders demands.


Hardshell covered pads reduce friction against the ground in case of a fall. Maximum protection from impacts often associated with pedals, rocks and other objects found on varied terrain or falls from great heights on concrete or wooden ramps.

Amplified Softshell Construction

Softshell look and feel but Hardshell performance. A thin and flexible pierce-proof insert inside the pad on top of the multi-impact soft foam secures the foam and your joints from crushed rocks or other sharp objects. Your choice when you want comfortable soft but reliable impact protection. (Insert removable for some products).

Pure Softshell

Soft foam protection for the softest and most flexible performance. Your choice when you prefer wearing the most comfortable pad but still want reliable support

ACF impact foam

ACF (Arti-Lage Foam) is engineered to mimic the physical structure of human cartilage with molecular freeflow technology. Flexible and soft in the normal state but when met with impact the molecules in ACF form a hard, protective shell. The remaining impact energy is converted into barely noticeable heat before it can reach the body.

EVA foam

EVA provides great shock absorbing properties, stress-crack resistance and low-temperature toughness. It can be used in multi layers and backed with hard shell caps for a solid performance.

Memory Foam

This smart PU foam gives you a great level of comfort and safety. It absorbs impact, is comfortable and soft to wear and adapts to create an individual fit.


High impact strength and low friction caps for use on rough and concrete ground.




Maximum comfort

We create protective gear that is so comfortable and functional you forget you’re wearing it. And when you do fall back to earth you’re protected against the worst gravity, your bike and  hard earth can throw at you.  

Horseshoe Shape

Our custom Horseshoe shape that greatly surrounds knees, elbows or shoulders. The compression-moulded foam pad with a raised top part sits perfectly around your protected joints. This shape minimizes shifting and down-sliding to keep your pad in place during action.
