The bike helmet is designed to protect the head of a shock and attenuated impacts to the skull of a cyclist in drops. If the helmet is apparently not damaged, it can be fragile and cracked in places which aren't visible. Ride with a helmet which has already received a shock can be very dangerous because no longer play a protective role.
- Visible deterioration
If you see with the naked eye deterioration of the Marushin 888RS ET Shivan Flat Black (small cracks, which straps snapped, things that come off) it's extremely important to change the helmet. Only a good helmet can protect you effectively.
- After a few years
Depending upon your practice and the number of outings, it's recommended to change the helmet if it gets too old. A helmet may be too old elements and materials that age less well than others, especially if your headphones are stored in a cold or wet.
- Change in subject
If you wish to address a cycling discipline different from what you are doing today, you will need a helmet which will fit best in your new practice.
- Other possible reasons
A number of other reasons exist: simply the desire to change, the desire to have a Marushin 888RS ET Shivan Flat Black lighter, more design, airier and so forth.
Selection of helmets (Size of bicycle helmets and bike):
The helmet sizes are listed as "53-56cm" which is the minimum and maximum circumference of the head. To find your size, simply measure the head circumference, outline his head in the front, where it's wide, with a flexible meter.
- Choose a helmet for child
Choosing a helmet for child comes first by appropriate sizing. Indeed children grow up fast and many sizes available. Also make sure they have air pockets and that they meet the standard which validates the quality of the bike helmet.
- Choose a helmet for city bike
The helmets for city bikes are often relatively round and include many vents. Check that you can wash the helmet completely, or at least the inner parts detachable foam. Check the standards that validate the quality of the product.
- Select a road bike helmet
Once the size of your head circumference well defined, it remains only to be careful about certain things: the presence of vents, the method of washing the helmet standards and possibly the weight of the helmet if you are looking for a lightweight. Helmets road bicycles are usually lighter all the possible, the greatest difference being in design (aerodynamic shape and color) helmets.
- Choose a bike helmet
In the case of a conventional use of hiking and cross-country helmets are similar to those of city or highway. They must have many vents, must be certified and relatively light. Bike helmets may have shields that prevent rain or the projection of mud.
- Choose a Freeride bike helmet
If you make the bike very involved, with jumps, downhill mountain... etc.. It is quite important for a beginner as well as for an expert to have a helmet. The helmet is extremely interesting because really protects the entire head in a fall, jaw included. The falls in these disciplines can be very serious and very violent, hence the importance of such a helmet.
The helmet must wrap his head well and it should not be open space and play between the two. It should be straight and cover both the top of the forehead and the back of the head. Crash helmet back one must touch the ground.
The strap must not be too tight or too loose. To ensure the helmet is set, turn your head from left to right and from top to bottom: Neither the helmet and the strap shouldn't move or affect you.
A bicycle helmet is designed exclusively for cycling. You may not use these headphones for sports. Similarly, the full-face helmet for BMX or Freeride bike is not intended and approved for the bike, or anything other than cycling.
