Bicycles on cast disks are still a rare phenomenon in Russia. Still, hundreds of times more people ride bicycles with regular and spoke rims. Nevertheless, cast bicycle rims have their advantages.

Specifications
The parameters by which casting is selected instead of spokes - as an alternative to the classic spoke - are as follows.
- The number of transitions connecting the sleeve and the rim circle. The more there are, the more confidence such a wheel instills. If it is possible to choose a wheel with 7 supports converging in the center - instead of 5 - prefer this one.
- Rim diameter. Just like the outer dimensions of a regular spoke wheel, the alloy rims vary in sizes: 24, 26, 27.5, 28 and 29 inches.
- Rim material and structure. As you know, the box-shaped double profile of the outer circumference of the aluminum rim is almost the only option. Less commonly used is a magnesium-aluminum alloy.
- Bushing material... If it were 100% aluminum, it would quickly wear out - steel balls and other parts of the bushing drum would have made grooves in it for just a dozen or two kilometers. The use of aluminum ball bearings and a hub is generally not justified - the mechanism, again, would collapse under the weight of the rider. The disc wheel hub has a steel insert - like the one-piece hub that snaps onto a regular bicycle.
- Cyclist weight and riding style, road quality - characteristics, exceeding the values of which will immediately lead to irreversible damage to the disc rim.

Advantages and disadvantages
The advantages of a cast rim over a disc rim are obvious.
- Less wind resistance when driving. Narrow and flat supports (there are several of them) offer less resistance to air flow than 36 or more spokes.However, only riders will fully feel this, for whom 30 or more kilometers per hour on a bicycle is the norm of life.
- The rim will not "eight" over time, if shocks and vibrations are below the permissible values.
- The cast wheel does not need to be serviced. Even when you wash your bike after every ride in mud and mud, removing build-up from the "ribbon" blades is much faster and easier than washing them off each of the many spokes separately.
- High strength of the wheel. It can support a cyclist's weight of up to 110 kg with a quiet ride - this is stated by most manufacturers of "cast" bikes.
- Outstanding design... Alloy wheels for a bicycle bring it closer to the car - in terms of the appearance of the wheels.

Cast wheels are also full of disadvantages.
- Sensitive to strong shocks... In case of a “hard” high-speed hitting tram rails or “cutting” into a curb, support or post, the wheel is not repairable and is thrown out immediately on scrap metal. Driving on rocky roads and dirt, broken asphalt for several tens of kilometers will lead to beats incompatible with normal driving. If the steel spoke "forgives" the owner of the bike for such negligence, then for a cast spokeless rim it is fatal.
- Less weight is still with conventional wheels. By paying for the cast ones, you will get an average increase of 325 g per wheel.
- Increased rigidity... Unlike steel spokes, which absorb unnecessary vibration, aluminum wheels "shake the soul" out of you in potholes. Combined with the aluminum frame, you get even less ride comfort. If it were not for the suspension fork - normal, and not the visibility that is put on inexpensive bicycles under 20 thousand rubles - and the same properly working rear suspension, you would quickly no longer want to ride such a bike.
- Finally, the high price tag will blow your mind. You can reduce your costs a little by ordering a similar bike from a Chinese or European store. If the model is the same, you will save no more than 20% of its cost in Russia. For the reduced price, you will pay with a long wait - from 10 to 100 days.
If a bicycle is not a means of helping you to emphasize your individuality, but just an economical mode of transport, then forget about alloy wheels and go on classic wheels further.

Manufacturers
Unlike dozens of popular companies specializing mainly in bicycles and spare parts for them, bikes with cast rims are produced by popular car factories. Therefore, the cost of such bicycles is much higher. For the amount paid when buying a bike from Mercedes or Audi, Green Bike, Porsche, Audi, Ferrari, Hummer, Lamborghini, you can buy a multi-speed folding bike from, for example, Strida or Dahon, which uses parts of above average quality.
At the same time, you are most likely to protect yourself from counterfeiting. An alternative solution is to buy a regular mountain or road bike with spoke wheels and replace the spoke rims with solid ones.

BMW Due
The BMW Due has a slightly arched frame. Cast rims have 6 blades. The rear wheel fender is sharpened. Despite the absence of a significant number of gears, the bike is able to pick up speed quickly. The wheels are equipped with disc brakes. The fork has a spring-oil shock absorption, which allows the bike to ride on rough terrain with dirt roads. But the color of the frame - neutral white, aggressive red, etc. - does not affect driving performance.

Review overview
Buyers speak differently about the bicycles of eminent auto brands. Some emphasize the elegant - in comparison with the models of bikes with simple spoke wheels - appearance, presentability of both rims in particular, and the entire bike as a whole. Others emphasize that these bicycles are not adapted for aggressive driving with hard braking and bad, "killed" road. Opinions are divided here as follows.
Alloy wheel bike - similar to a car from the same manufacturer: the three-bladed wheels look gorgeous. The subtext here is this: a car owner who has bought an X-6 from BMW is fired up with the idea of buying a bicycle, for example, a model X-, for active "after-work" rest. Or he looks for - and finds - a bike from competitors. Not a bad combination - for example, a BMW-X6 car and a bicycle from Mercedes-Benz. To mention in passing that “I have a BMW and a Mercedes” - to fan myself with an aura of mystery and consistency, to intrigue the listener.
In addition, expensive bicycle models cost from 50 to 100 thousand rubles. - from the same factory BMW or Mercedes really have a good body kit and above average quality. This is also mentioned by the owners and fans of "auto-branded" bikes.

A bike with cast rims is something that, on the contrary, should not be invested in. This is the desire to show off in front of friends, acquaintances and passers-by. It is impossible to straighten the rims without spokes - as soon as the rim is "led" to either side, you will immediately feel the beats and / or vibration while driving. The damaged wheel is replaced urgently. Otherwise, a quick and inevitable end will come to the bushing mechanisms. For an amount of about 15,000 rubles, which costs only cast rims (bicycles in the middle price range emphasize this consumable item), you can get more than durable and wear-resistant spoke wheels that can withstand at least several thousand kilometers of off-road and bumpy roads before there will be "eights".
Or the surplus money spent could be invested in improved derailleurs, brakes, or fork damping. A bicycle with cast rims, notes another segment of users, is nothing more than a waste of money. And what a shame, this money will be spent on something with which it is better not to meddle outside the city streets and avenues in the city center. This situation hits the residents of villages and settlements, where not all street roads are in good condition. Buying cast rims, Russian bikers will sharply limit themselves in the freedom of riding.
Instead of being free to travel wherever you want - from forests to country roads and dachas - they are "tied" to gas-polluted highways, avenues and overpasses. This applies primarily to weekend trips out of town or in the region, multi-day cycling trips in the region or federal district of Russia, cycling trips around the country or abroad.

It may happen that after buying a "cast" bike, you change your mind and immediately sell it. The best way out is a model bike with cast wheels, easily replaceable with regular spoke ones. This "downgrade" will save you the rest of the body kit, and you will continue to ride your favorite bike.
However, if you want to buy a bike with alloy rims, weigh the pros and cons. Common sense will tell you the best solution. If you want something unusual, you always have to sacrifice something.
