Cycling class: purchase and modification of long-distance cycling bicycles [Photo]

Get a good car, long distance ride will be a lot of comfort

Some of the more professional mountain bike shops have a lot of different parts sold separately. You can choose your own combination. Let the boss help you assemble. If you buy a ready-made car, the domestic price of a relatively affordable price may be better for Amini.

Number of gears

At least 10 speeds or more (considering price factors), in fact, the key is the maximum/minimum speed ratio, which is crucial for the efficiency of climbing, gentle slopes, and leveling the road. In fact, the larger the number of gears in general, the greater the difference between these two values.

Width, if riding a more complex road (usually difficult to avoid), my personal experience can not be less than 1.75 inches in the front wheel, the rear wheel can not be less than 1.375 inches. Or else it will be very troublesome to run into bad roads.

Outer tires generally have a deeper pattern, and the more complicated ones are chosen. The more important thing is to look at the curvature of the tangent portion of the tire and the ground after the suffocation, and the arc is small. When riding a flat road, the contact area with the road surface is small and the resistance is small.

Inner tube, choice thick and strong. If you buy a full-loaded car, after you buy a car, it is best to remove the original inner tube and replace it with a solid inner tube. The master of the car repair will recommend the "Zhengxin" card to me. Ordinary thinner inner tubes will be very fragile on complex bumpy roads. Even if they are not tied, they will get up on their own. After the wheel rims have adjusted the spokes, knock out the spokes protruding from the outside of the rims, and then put a circle of canvas tape to avoid the spokes from wearing the inner tube.

Cages

The kettle I suggest is still in the front basket. I don't recommend riding and drinking while riding. This can be a safety hazard. You don't need to do this if you don't have a car and you don't care about time. Take a break every 30-60 minutes.

handlebar

At least one must have a ram-like handle (a deputy). I support it on 90% of my time. It is also preferable to install a pair of forwardly projecting auxiliary arms that allow the elbows to stand on the upper body. It's more comfortable.

Seat

The general mountain bike seats are small and hard, and they must be replaced by a big one with good elasticity. Even the seats of ordinary bicycles are much better. Otherwise, riding around for a long time is not about.

Brake

To select the brake part is easy to adjust the elasticity. If you are riding long distances and you have a lot of bad roads, it is very likely that the rear wheels will be caged. In the middle of the road, you can only use the loosening brakes for emergency purposes. The brake actuator is preferably a metal frame, not just a wire.

fender

Many mountain bikes have short, arc-shaped fenders that are purely look-alike, with little mud. To choose a longer one, in line with the curvature of the wheel, but the installation can not be too close to the wheel, so easily blocked by mud.

Roulette

It is best to have crimped teeth on the teeth so that the chain is not easily tripped.

Rear frame

The general mountain bike does not have to install one. When riding, the luggage bag is tied with thicker ribs, like ribs can be bought in the general motorcycle accessories shop.

Reflector

Reflectors must be installed behind the car, or reflective stickers, and must not be blocked by the bag. In this way, security will be more secure when walking through the night or crossing the tunnel.

Front basket

The screws in the basket are most likely to fall off after a long bump, and can be twisted with two screws.

Of course, the quality of the car does not determine whether a final trip can be achieved. Many people are riding an ordinary bicycle, taking a bad walk on the plateau and traveling all over China. However, in any case, if there are conditions or try to choose better equipment, after all, the quality of the car will have a great impact on the smoothness of the trip.
