4 important invention in the whole bicycle development history

Different bicycle manufacturers seems introduce a lot of new products and new technology every year, it looks like that it is difficult to keep up with the bicycle trend. However, real innovation is rare, and now these new marketing concepts and technology are actually those historic technology .

1.Disc brake

In recent years, the disc brake appear a lot on the road and develop gradually, but the mountain bike has been using disc brakes for 20 years.in fact, if you check carefullly, you will find some travel bike has been using it 40 years ago. In the middle 1970s, Shimano developed the mechanical disc brake BC-300 and sold the specific hydraulic disc brake BC-200 for bicycle.

In the same period, there are brands such as Phil Wood and BridgeStone also joined the disc brake market.
Prior to this, Schwinn use mechanical disc brake in the Manta-Ray stroller, During 1970s,when muscle car and modern fashion is popular, lever speed, rubber cushion, anti shock front fork and bald tires have been appeared.

2.Synchronous speed

Nowadays,synchronous speed is just like a basic feature of Shimano Di2, which allows the rider to control multiple transmissions through a finger, this design appeared in the 1990s and was still a relatively obscure product. The system uses a single dial to control front dial and rear dial of 24 or 27 speed bike, the two outlet holes show the shift mechanism link the front and rear dial through the internal complex mechanical structure.

3.Anti shock front fork

Although it can not be concluded that this is the first anti shock front fork, but this is definitely the first patent which can be checked for telescopic anti shock front fork (rather than connecting rod), GW Sage designed this front fork in 1922, It uses a telescopic structure, and the spring were hidden in the tube, it has been very close to the current suspension front fork design.

4.Super wide tire with super wide rims

In the past few years, the tires and rims in the bike began to grow in the direction of width, it seems we can see “Plus” signs everywhere, but as early as 15 years ago, Nokian had produced a 3 inch width DH exterior tires, named Gazzaloddi.

For the wide rim, it is generally believed that the width should be about 33 mm, and during that time Sun Ringle has produced, 46 mm width exterior DH rim.

Why not dry cleaning your bicycle ?

Cleaning is a big problem for bicycle, especially the axis,hub may rusted if water penetrated. Why not try dry cleaning your bicycle ?

1.Dry cleaning the chain and guide wheel

In order to avoid useless work, before cleaning the chain, we recommend you to check whether your chain needs to be replaced, excessive stretching of the chain will accelerate wear and tear of the driving system and pull down the riding efficiency. We don’t recommend cleaning chain with kerosene or industrial degreasing agents, they will easily wash out grease inside the chain,the best choice is to clean lint free cotton cloth with specific chain cleaner for bicycle.

First spray the specific chain cleaner on the chain and cloth, wrap the bottom of chain with the cloth, and turn the crank in the reverse direction,you will see dirt on the cloth,if the cloth is too dirty, then replace a clean cloth and continue to wipe until the chain became glory again.

During the cleaning process, it is recommended to clean the guide wheel and plate, to avoid the dirt on the guide wheel and plate stain the chian again immediately,be careful not to scratch your fingers during cleaning.

2.Dry cleaning the flywheel

Remove the rear wheel, spray the specific cleaning agent on the flywheel and cloth.Place the rear wheel vertical stability, embed the cloth into the flywheel gap, pull back and forth, we recommended that to cut the cloth into strips so that it can improve the utilization rate and save cost.If the flywheel is very dirty, you may need more cleaners and cloth.

3.Dry cleaning the bicycle frame and the wheels

Before cleaning the frame, remove the front and rear wheels, remove the code table, lights, tool kits and other accessories, remove large particles sticked during the spare parts gap,pull the stalls to the lowest level to keep the chain relaxed. After the preparation work is completed, spray the diluted cleaning agent onto the frame, and use a cloth to wipe the surface, pay attention to the back and bottom of front fork, rear triangle inner side, bottom bracket, folder and other parts, if the bicycle has electronic speed meter , power meter and other electronic components, you need to be very careful during clean. Using the same method to wipe the rims, spokes, hubs, check the tires, brakes, and so on. If it is a carbon fiber wheel, it is recommended that the wheels should be completely dry and then replace. Otherwise, abnormal sound may occur.

Do you really know how to ride a bicycle ?

Don’t know how to ride a bicycle ? Come on, i learned it when i was very young. Perhaps this is the first reaction you see this subject, but if you buy a sports bike and want it to bring benefits to your body,health,and life, the question is not so simple.

1.Is your bicycle suitable for your body?

Buy a bicycle must be in accordance with your own physical data, buy
the right bike size is the basis of scientific, healthy bike riding. After buying the bicycle,you must do scientific adjustment and setting,
this is not a simple matter, we must ask experienced professionals to
operate for us.

Is the settled bicycle fit your body forever?

No, because your body is changing at any time, when you started
riding a bike, the leg strength is small and the back strength is also
weak, can’t lying riding in a high position like an experienced rider,you must adjust your bicycle settings in accordance with your body change.I have seen an introduction from a magazine that a Japanese
riding a bike, have adjust the bicycle for six times half a year after he bought the bike.

2.How should i ride within the three months after i bought the bike ?

Perhaps the incentive to buy a bicycle is imagine fast speeding as others, and sliding in the electric vehicle driver’s surprised eyes.
But please take care in the first three months,human body is made of meat after all, not steel. Unless you have a good physical basis, often adhere to higher intensity sports. Common people still need to set up a good foundation, and gradually exercise to improve leg strength, back
strength, heart and lung function, tall buildings firstly need a solid foundation.

How to set up the foundation ?I suggest to focus on the following points:

2.1. Control the bicycle

Whether it is a mountain or road bike, control the bicycle is the most basic requirements for new riders, especially high speed cycling and steering, be careful,speed is a very sharp knife, master bad will hurt yourself severely. Control bicycle requirements rider to be familiar and proficient with his own bicycle,and gradually control the bicycle like your own legs.This is easy to say, but hard to do, rider need slowly experience. Control the bicycle is the basis, it can help you to protect your life in critical moment.

2.2. Strength

The strength required to ride a bicycle may be different from other sports, with the same riding purpose, riding a mountain bike and a road bike strength emphasis is different too. So strength exercise for riding a bike must be scheduled, we must step by step. Physical strength exercise is a long process, there is no shortcut, rider need long term insist and pay sweat. Couldn’t be anxious, must not do too much exercise after long time no practice,this can only cause harm to the body.

2.3. Riding Frequency

Riding frequency is important factor that decide how long you can finally ride,riding frequency is closely related with your heart beat, so at the beginning try not to look at the speed table only, but
pay more attention to the frequency table.
