For maximum safety RUMBLE must fit tightly and be correctly and

securely fastened, so it cannot be taken off neither by pulling it nor by

rotating it around the head (see figure 1).

If it is too big it may slide down over the eyes or turn in a lateral direction

due to movement during riding, thus blocking visibility.

Do not use scarves or neck guards which could make the strap slide and the helmet fly off in case of crash.

The function of the helmet is to reduce stress on the user’s head in case of crash; this happens through a partial destruction and/or deformation

of its components (mostly the external shell and the internal polystyrene shell). In this way, part of the energy generated by the impact is

absorbed by the components of the helmet, thus reducing the vibrations on the user’s head, eliminating or limiting the risk of traumas.

The protection capacity of the helmet is not endless and certain crashes may generate such high stress that even the energy absorbed by the

helmet is not enough to protect the user from injuries: no helmet, even top quality helmets, can protect the head against the forces

generated by any type of crash.

The integrity of the shell and of the inside is essential to assure maximum performances in terms of safety. RUMBLE was designed to absorb

crashes through a partial destruction of the shell or some of its parts that could be damaged after a crash even if it is not readily visibly. If the

helmet suffers further stress it might not be able to offer the maximum level of protection.

Do not use a helmet that suffered severe blows even though the damage is not readily visible; if the helmet is damaged it must be

replaced.

It is extremely dangerous to modify the helmet by sticking or gluing anything on it.

Do not cut or punch the helmet’s shell, do not insert screws or paint it.

Do not change the internal lining of the helmet, particularly never cut or change the inside polystyrene padding: changes to the shape of the

internal polystyrene shell can affect the safety features of the helmet.
