BEST MOUNTAIN BIKES UNDER 500 For EVERYBODY

Among the innovations on the cycles of any type, disc brakes have become a standard for some. But what is their real usefulness according to the practice?Its not that bad to buy the best mountain bikes under 500 besides they are quality mountain bikes that are cheap.

When we talk about ATV, its precellence is indisputable for a long time. The disc brake is incredibly more efficient than traditional skate systems. On the road, where the needs are different, the question deserves to be examined in the light of possible circumstances.

After all, today we make "classic" brakes high-end devilishly effective: the very stiff calipers and various pads, whose specific compositions are a function, not only of the material of the rim (very often carbon for this which concerns the pros) but also the desired compromise between "biting" and durability. We know how to do it. The proof: the Tour de France riders still prefer them to the discs in 90% of the cases.

Nevertheless, discs are more and more common on road bikes. Aside from the pressure from manufacturers wanting to renew the market, why?

First, the disc brake prevents dangerous overheating of the rim. Indeed, in some cases, especially during long descents, the friction of the pads on a carbon rim (which unlike aluminum, very poorly disperses heat) can raise the temperature of the rim until explode the tire. .. or compromise the integrity of the rim itself, it has already been seen.

We must know that in terms of braking, we are all different: and if the pros or the good descenders do not apply their brakes enough, others bring them to a boil in three turns. This is not only a matter of size (the slowing down of a heavier subject, of course, requiring a greater amount of energy, and therefore of friction), but indeed of "style": it is better to brake hard on twenty meters than to keep a finger on the brake at all times.

Its effectiveness is insensitive to the rain: a disc of 140 or 160mm dries instantly, as soon as the pads touch it, which is not the case of a rim of circumference (about 2 meters) important. Disc braking remains responsive in the rain, which can be valuable. In addition, provided it is a model with hydraulic transmission (not cable), the most powerful braking requires no effort of the hand. On the moment this difference may seem negligible, but on a long descent the hand will feel and, above all, the precise dosage of braking power.

In terms of the disadvantages of disc braking, note that obviously, the heat spared on the rim is supported by the disc, which may be burning at the end of the descent. It is also criticized these metal cakes to be potentially cutting, which no biker complains.

To conclude simply, it can be argued that the disc is a real advantage to those who practice a lot in the mountains, and / or in all weathers. In the city where, in wet weather, the responsiveness is appreciable. But in Touraine under the sun, stirrups are perfectly suited, even in competition.


 

Can we have any wild animal at home?


Want to adopt a turtle? A way? A tiger ? Be careful, it is forbidden to build a Noah's Ark at home without having an authorization. And any request is examined by the prefecture according to each species.

NAC. Tuesday, September 8, 2015, the inhabitants of Sourn, a small Breton village near Pontivy ( Morbihan ), have reported to the gendarmes a wandering animal a little special ... a kangaroo! Verification made, it was actually a Bennett wallaby, a marsupial from Australia actually resembling a small kangaroo. The beast is no less exotic in the land of korrigans. Yet she had not escaped from an animal park, but from an individual who had been "offered" the day before as a birthday present. According to our colleagues from Ouest France, the gendarmes have made Speedy the wallaby to the young man in his 50s, who will have to do some work to make a suitable enclosure. And that's all. Does this mean that one can own any wild animal at home as a domestic companion? " No ," says Yves Roussel, environmental inspector at the National Office of Hunting and Wildlife ( ONCFS ) in Vannes, there is a specific regulation .

3 profiles of wild NAC
Problem: this regulation is both little known and complex since it depends both on animal species (large carnivores, reptiles, etc.) and their status (dangerous, invasive species ...). It is defined by the decree of August 10, 2014 . Each person wishing to host a wild animal at home must therefore check before buying or adopting it if it needs a prefectural authorization of detention. In any case, " you should know that the owner of a non-domestic animal will be considered a breeder, even if it only accepts one wild animalYves Roussel says that to do this, it is better to call the department of the prefecture in charge of health and animal welfare to know what to do.In short, three cases may arise.

1) The detention of the animal does not require any formality. This is the case, for example, of the green-col duck insofar as it receives less than 100 individuals.

2) The detention of the animal is subject to a prefectural authorization . The Bennett wallaby is particularly subject to this, as it is considered in metropolitan France as an invasive alien species. The wallaby acclimates well indeed in our latitudes. The future owner must therefore ensure good housing conditions (adapted pens) to prevent the animal from escaping and reproducing in the wild.

3) The animal may only be detained by a professional (animal park, pet shop ...) which is subject to a certificate of capacity and must have a prefectural authorization of establishment opening. " The certificate of capacity is in some ways the equivalent of driving license , says Yves Roussel.The prefectural authorization opening establishment would be the vehicle's gray card ". Both are therefore absolutely necessary before having animals falling into this category.

Finally, most of the time the breeder must have his animal identified. He must also sometimes report his loss or death. If he wants to sell it or sell it, he has to get a Cerfa, just like for a car. It must also take into account allowable quotas for certain species, particularly if it wants to breed its animals. This is for example the case of Hermann's turtle; each breeder can only have 6 specimens. " We also consider their part and their product, especially ivory: the status of the species concerned continues to be applied to them ", adds Yves Roussel. According to the code of the environment a violation of this regulation of detention of non-domestic animals is punishable by one year in prison and a fine of € 15,000.
