Let’s face it
Just a few examples will suffice. The weight of a conventional disc without rubber is on average 1100. 1200 g, and the weight of alloy discs, which is declared by the manufacturer itself, is 1465 g (Grimeca Wheels, 26 “, made in Italy).
It is also a very common myth that alloy wheels are stronger than spoked wheels. Also Not quite true. In terms of strength, only carbon fiber discs for a bicycle can compete with ordinary wheels. But their price cannot be put next to the price of a spoked rim.
Alloy wheels cannot be repaired and are subject to destruction during mechanical overloads. one specific curb is enough for the casting to be permanently out of order. Abroad, the situation is somewhat different. no one there will even think about leveling or rolling out a cast wheel. straight to non-ferrous metal, because health is more expensive. And one more point, Not entirely clear for those born in our open spaces. On the most budgetary MTV over the hill, they try to put it in the casting. Why? Right. It’s cheaper. And we have him canonized and hung up the corresponding price tag.
A spoked wheel perfectly holds impacts in all planes and can be easily repaired. tightening the spokes, straightening, in the end, rolling out the rim. The spoke will allow you not to survive on the road that the wheel can crumble at any time and the trip will end in disrepair.
Advantages and disadvantages of alloy wheels for a bicycle
Very emotional and cocky. Extravagant and extraordinary. Such thoughts come to mind first of all when you see a bicycle on alloy wheels. We will NOT draw any conclusions yet, but consider the cast wheel from a pragmatic point of view. Let’s omit the aesthetic component for now.
Who needs alloy wheels?
First of all, athletes. And they are needed, like air. The fact is that in single races on a cycle track, carbon or fiberglass discs are used. They are made in a variety of ways, from hydroforming to injection molding. When used on tracks, a blade is placed on the front wheel. 2-3 ribs, and the rear wheel is made solid. On closed tracks, where there is no need to deal with windage, they put solid wheels in front and behind. Casting in track racing cycling is a must. That’s why:
- Ease of construction;
- Sufficient rigidity for the track;
- There is a need to install brakes;
- Reducing the coefficient of air resistance;
- Improved handling.
With the emergence of an unhealthy trend, it puts molding on any bicycles, such manufacturers as HED, HSon, Lightweight offer them for free sale. On bike tracks, a cheaper version of the fight against air resistance is also used. shields, which are worn over the spokes.
Everything is so bad?
Alloy wheels are rarely produced with a single rim, knowing their susceptibility to destruction. Therefore, the double rim will give strength and confidence.
The design of the blades of the cast disc allows for better aerodynamic properties. Let it be noticeable This is not immediately, but the fact will warm the soul when you remember the spent 120.
Structurally, it is possible to configure not only disc brakes, but also V-Brake. Such an opportunity, of course, will expand the casting halo.
We should also mention the beautiful fables on the cast wheels of BMW. We will not announce the for them, but you can admire.
Here’s a snippet from the manufacturer of how great it is to ride Teny Rims in the USA.
Every bike rider has the right to decide if he needs alloy wheels. That this is unusual is an indisputable fact. But whether such unusualness is good is a moot point.
Sometimes people say. if I now buy a bike from 26 “wheels, then most likely I will not be able to upgrade it in a few years, because manufacturers will stop producing components for this size.
For example, despite the fact that the standard steering 1 1/8 “has long been completely squeezed out by the new standard, there are still a lot of proposals for forks with the old steering rod diameter, so there will be enough wheels and forks for 26″.
It is clear that the assortment will dry up from year to year, but it is unlikely that a person, having in his hands, in general, an outdated bicycle, will think about a top fetishistic configuration.
Therefore, if you are now in the selection process, and cannot decide on the diameter of the wheels, then the complexity of subsequent upgrades is the last thing that you should worry about.
So which bike to choose. 26 or 27.5
First, a tip for practical people: if you need a bike to ride. close your eyes to the diameter of the wheels, and choose exclusively in terms of price / equipment ratio. You should care what kind of mechanics you get for your money.
We must accept that the new standard is not a momentary marketing ploy, which will soon be replaced by something else. I think 27.5 “- this is serious and for a long time, therefore, if the question of money is not too acute, choose this size, simply because it is the present and the future.
Does it make sense today to buy a bike from 26 “wheels
An important question on the agenda is whether the 26-inch size will disappear completely in the near future, and is it worth buying a mountain bike with such wheels now. In 2019, the question is already on the second. and where to find a decent bike with 26 wheels?
Seasoned cyclists remember how slowly and gradually the niners gained popularity: first the need for hybrids ripened, then the first clumsy 29ers began to appear on their basis, and only at the end of this evolution the bicycle world began to massively switch to a new wheel standard.
But with wheels 27.5 “marketing made a very rapid revolution, in just a few years many bicycle brands decided to transfer their model range to this size.
Are 27.5 wheels really better than 26
Let’s be honest. many decades size 26 “suits millions of cyclists, remember yourself. have you ever wondered that a mountain bike should be somehow Different? The difference between These two sizes is on the verge of feeling and faith, on the one hand, wheels 27.5 “slightly heavier, but on the other. they should roll a little better off-road. Claiming that one of THESE two standards is clearly better than the other is from the evil one.
If the difference between 26 “and the 29er lie on the surface Pros and cons are visible to the naked eye, then with regard to question 26vs27.5, I would recommend readers to stock up on healthy skepticism.
However, on the other side of the scale is the axiom that a larger wheel size is almost always a good thing, and a new size is exactly the middle ground between small and large diameters. 27.5 “suitable for all cyclists, both tall and short, plus a slightly better roll rate compared to 26”. Marketing by marketing, but the main thing is that it is still a step forward, not backward.
So far, my opinion is: the new standard is the normal development of modern bicycle marketing, creative search. I love everything new. # 128578;
Will size 26 be missing “quite
In fact, it’s already gone, try to find 26 in the range of top bike manufacturers. A few years ago, I thought that marketing would spread these standards across different niches: 26 would remain in the hobby class for beginners, and 27.5 would become a “sport” type. But it is clear that the industry has decided to completely bury the good old standard.
Perhaps some brands targeting the mass market will NOT stop releasing 26 “, they will simply be equipped with entry-level equipment for the very beginner cyclists.
These are my thoughts on the near future size of mountain bike wheels, it would be interesting to know what my dear readers think about this.
What do you think will be 26 inches? Are you going to switch to this standard when buying your next bike?

26 ” Bicycle Cameras
A bicycle tube is usually made of butyl rubber or latex and is located inside the tire and inflated with a pump. Often there are situations when a bicycle tube is punctured, but it is easy to replace it. The material of the product is selected depending on the type of bike: mountain, road, children.
There are many different types of cycling tires, so it is important that you choose the right size for your bike, this will determine how much the tube costs on the bike, for example, the price of 26 ”wheels will be lower than 28”.
How to choose the material and size of the bike tube?
The tube must match the tire of your bike to avoid overstressing or pinching, which can cause punctures, and the material is chosen based on the type of ride you prefer. Butyl rubber chambers. A more common option and are suitable for road / road bikes, and latex, due to their resistance to damage, will be an excellent solution for mountain bikes.
When it comes to replacing a bicycle camera, the question immediately arises: how much does it cost and how do you know which size you need for your bike? There are many sizes of wheels for road, BMX, mountain and kids bikes. The BMX wheels, in particular, can be divided into 26, 27.5 and 29 inches. B do not forget that all tires have different widths.
These two parameters: wheel diameter and tire width are the most important when choosing, and you can find out them from the bike‘s registration certificate, they are also almost always written on the sidewall of the tire. There will be two numbers, for example: 26×26, 26×2, 26×0, 17×26, 26×4, 26×3, 26×18, 26×1, 10×1 inches, the first digit. This is the diameter of the wheel, in this case the 26th, and the second. Tire width. If you buy a 26×2 camera on a bicycle with 10 mm tires, then it simply will not fit into 26-inch tires, and if the rubber is larger than the stated size, it will dangle and quickly deteriorate.

Types of valves for bicycle cameras
There are two main types of valves: Schrader and Presta.
Schroeder valves are typically used on low pressure tires such as kids’ and mountain bikes. These are the same nipples that are used on all car tires and are often referred to as automotive type valves. Schrader valves have a spring loaded core, and the center pin can be pressed in with a thin object to release air from the tube. Spring mechanism keeps the nipple closed.
Presta nipples have a thin diameter, sometimes threaded to accommodate a retaining ring that holds it tightly in the rim when the tube is inflated. They are usually found on high pressure tires such as a road / road bike. To inflate or deflate the Presta nipple, the top must be unscrewed to allow the valve core to move freely. This will allow it to open and close. In this type of nipple, it is the air pressure that closes the valve, and then closing the upper section keeps it in this position.
Another option. Dunlop valve, which is rarely used in modern bicycles. They look like a cross between the aforementioned two nipples, with a wider bottom section, like in Schroeder, with a collar and a narrow top section, like in Presta. Since the inflation principle is the same for Dunlop and Schroeder, old valves can be easily replaced with more modern ones.
