Do fitting before buying a bike.
Important thing always repeated three times:>
Basically no one (pay attention to the “basically”) is able to find all the accessories and frame size that are fully consistent with their own bodies.
So fitting is a very important step for choosing a bike.
I have seen a store sell a bike frame in 515mm to a girl of 174cm.
I have seen a store sell a TT frame in 540mm to a guy of 176cm.
I have seen a store sell a bike frame in 535mm to a short buyer of 172cm with a stem in 11cm..
The store’ s nonsense , is just an obstacle for you to love this game.
How to buy a road bike for your own? in addition to budget, size is very important, knowledge is very important.
How to buy a road bike for your own is not a simple problem of buying a bike, but rather a choice for a sporting tool / commuter tool.
The utility model relates to a road bike, which is suitable for long distance and high speed movement. It is not suitable for dirt road, stone road, but can climb all proper road slope (asphalt / cement road), and can be faster than mountain bike, even easier that mountain bike.
So, how to choose a suitable road bicycle? A very first question you need to answer is, what do you need a road bicycle to do?
1, The use
Do you need it to commute or to exercise?
Your love is the mountain ride or speed passion?
Are you pretend to ride, or to be real?
Road bike can commute but are not good at commuting. The larger gear ratios and thin wheelsets, as well as brake performance, are not suitable for daily use in urban roads. If you’re just commuting, a mountain bike with flat handbar, mounted with a mountain bike cassette may be better for you.
2, what is a road bike?
Road bike evaluates as the time passes , then do not talk about the road bike of 10 years ago. For the time being just to try to define the current road bike.
The necessary road bike composes with, hand shift (more secure transmission system), 700C*23-28 wheels, correct frame geometry(although each frame geometry manufacturers are not all the same, almost all famous manufacturers have marked data and more than 5 dimensions can be selected) on their basic frame geometry , and be able to adjust the size and the angle of the components (the vertical, seat tube), transmission parts above the level of Shimano 2300, at least 8 speed’s cassette(Merida 902 with 7 speed cassette can not be included in Road Bike Family, because the 7 speed cassette and related accessories are not compatible with other real road bike)
All the above conditions or better conditions of the bike can be called a road bike.
3, the first priority on the choice of road bike.
The first priority for road bike selection is not the material of the frame and the group system.
It’s frame geometry.
The geometry of the frame results to the posture of your ride and the health of your body.
Basically, you need a bike fitting before choosing a road bike. However, given the lack of culture and industry, the following gives a basic height and size selection.
As the current frame is not a horizontal frame, the size of the frame is not the frame length of the riser, but to see the equivalent level of the length of the tube.
Height 160-165, 505cm upper tube
Height 165-170,515cm upper tube
Height 170-173,525cm upper tube
Height 175-180,535cm upper tube
Height 180-185.545cm upper tube
Height 185-190,555cm upper tube
4, the choice of frame material
After you get the size of the frame you should buy from fitting or some kind of black technology, then you should consider the material of the frame.
Frame material is nothing more than steel, aluminum, carbon, titanium four.
Entry level is aluminum frame. For the price of the entry level of the steel, it can not offer very good steel, and too heavy.
Carbon frame of entry level, then, the Giant TCR C frame has an excellent cost performance, but the single frame group should be more than 3000 RMB. The titanium frame, feeling is important, so the domestic titanium frame can not generally compared to the titanium frame made in the United States .It is another story.
The material properties are discussed from several aspects,
Weight: carbon, aluminum, titanium, steel
Strength: titanium, steel, carbon (longitudinal), aluminum
Rigidity: aluminum or carbon, steel, titanium
Comfort: steel, titanium, carbon, aluminum
The above ranking is based on the consistence of the frame of the tube type and the thickness of the pipe wall and the thickness of the pipe.
But basically, aluminum frame cheap light, hard, but life is short, about 5000km or so you can consider to change to another.
Carbon frame, light, hard, but expensive, good comfort, the longitudinal strength is very obvious, the lateral strength not good enough, slightly delicate. Life in accordance with the number of years, there are more than 10 years of use.
Steel is the most high-end, expensive. A good maintenance is the premise of long life, high comfort.
Titanium frame is light, but also hard, high strength, but are built on the premise of good material selection and pumping. Known as a lifetime bike. Talking about the price, not comparable to a good carbon frame, but it is also expensive.
So for beginners, the choice is generally aluminum frame as entry. A little more budget, you can buy the carbon frame of basic level.
Do not believe in big brand’s aluminum frame, in fact. A 100% or even 200% higher price, will not necessarily bring you the same feeling of riding.
5, the choice of kit
Many beginners make a fetish of the group.
Ask 10 Speed as entry, and reject tiagra 4600,only want Shimano 105 group.
I say to all the people who are superstitious about the 105 group, what’s wrong with your brain?
Generally speaking, 2000 RMB is more than a starter kit,basically Shimano 2300 group, and now evolved into a 2400claris group. Shift is mainly changed into the lower position in handlebar , canceled the small trigger, but is still a 8 speed. For beginners, how long will you be able to hold lower position in handlebar? you just want to show your richness?
9 speed kit is basically equipped with more than 3000-4000 RMB’s bike, Shimano’s Sora group. I really do not understand what is the difference between a bike of 2000 RMB and the one of 3000-4000RMB. This is not to say that the Sora is not a good package, but the classification of the bike manufacturer is a shit.
Let’s talk about 105 and the choice of the 4600 kit. Price difference of about 50 RMB, the main difference lies in the hand shift into internal routing.
But you told me that 105 internal routing feels good? It’s one of the worst feelings. This design is a mess, the brake lever is too short, and it’s not friendly to hold the position for a smaller hand of Asian people.
6 wheel group
In general, the beginner’s wheel group is actually nothing to spent money on.
In general, the bike is equipped with a set of wheels suitable for beginners, such as R903’s aluminum wheels is a bit contrary to humanity.
But just on the group of bikes, let’s introduce the wheels of bike of entry level,as the following, according to the classification of the brand
Mavic: the AK wheel group known as Aksium, about more than and 600RMB from domestic builder, about 1200-1400 RMB from original factory, beginners the wheel group is very good. But only in the original factory.
Campagnolo:Khamsin, G3, CX and ordinary hair in two versions, CX version is ruthless, compatible with various roads ,more for climbing. A perfect dynamic balance of the wheels from original factory. Price around 1200 RMB.
Shimano: what? Shimano rs21? Do not tease, Shimano R501, only more than 500 RMB, entry-level most cost-effective wheel group.
Fulcrum:R7, to be honest, rarely seen –0 higher level R3 R0 is very popular.
7, equipment
Riding the necessary equipment are: helmets, glasses, gloves, riding pants.
Helmet, then 200 and the difference between the 300, 500-1000 no difference, no difference between the above 1000.
Should buy as expensive as expensive.
What if the likes of Oakley glasses, very good, but also to buy for your face shape. Shimano or, buy a 200RMB-400 RMB. Also can buy a little better.
What is riding pants, because I only wear braces style pants,the more expensive the better, in order to the lower part of the body and the happiness of life. Basic domestic pants of 200-300RMB, OK.
Gloves, at the beginning we like thick ones, and later prefer the thin.
Other thing, such as riding clothes. Best to buy full zipper cardigan.
About lock shoes
Don’t talk too much, just say, there is non-lock shoes and lock-shoes. More secure is lock-shoes.
