Why is the bicycle tire at the Tour de France bigger and bigger?

Tour de France is becoming more and more technologically advanced, from super aerodynamic frames, lightweight tires, oval chains, slippery outfits, to chains. Sprinkle with flour.

Racing teams will try everything they can to run faster. It is therefore interesting to see a “traditional” change appear in a technologically advanced world of bicycle races. We are talking about increasingly bigger tires with reduced pressure.

This is a new trend emerging at the Tour de France, and it has significant advantages: helping the car run faster and more comfortable in the harsh conditions of the real world. This type of tire has been studied by many experts, most notably the research published by VeloNews. It is also a “slap” to the long-held view that you will go faster if you use layers of narrower width and higher pressure.

This is the tire of Greg Van Avermaet, the reigning Olympic champion, who leads many laps of the Tour de France. It is 26mm in size compared to the traditional 23mm size.

Last week, at the Tour de France, Geoff Brown, head of mechanical engineering of EF Education First-Drapac p/b Cannondale, shared some information about this movement.

When asked about the trend of big tires and low pressure, which was completely opposite to what professional cyclists thought, but now it has become a must-have standard for top racing teams, he said:

“It depends on the surface of the track, but 10 years ago, the standard was 23mm tires with 8 or 8.5 bar pressure, or 115, 120 psi. Today, in normal racing, the tire size is 25mm and pressure 7 up to 7.5 bar for both front and rear wheels, which is slightly lower than the maximum of 100-110 on bicycles”.

It is true that in 2018, we have never seen a 23mm tire. Up to the present time, the most popular tire sizes are 25mm and 26mm. And while it’s difficult to compare tour speed based on width and tire pressure, studies and more and more teams using this type of tire say it all.

Even big riders – like Taylor Phinney, 1.98 meters tall and weighing 85 kg – use low-pressure tires like small, lightweight mountain-racer riders like Rigoberto Uran.

Which sports bike brands we should buy?

Perhaps this is a question that most people ask when they are thinking of finding their first sports bike. This question is really broad and it is hard to answer which one is the best, even for a long-time cyclist.


1. Giant bike:

This is a very famous brand of Taiwan, is a giant in the bicycle industry, has participated in many races around the world and also achieved certain achievements. Giant bikes have been in Vietnam for a long time (about 10 years or so, I don’t remember exactly), with a full range of racing bikes, terrain vehicles to city bikes, children bikes, folding bikes and even electric bike with many rich models.

1

Giant bikes currently have a lot of counterfeit products, you must buy very carfully, so buy in reputable shops that are appreciated by the ae on forums or invested with professional websites, submitted products. clearly displayed, with real photos and especially with the price listed publicly, absolutely avoid shops not clearly priced.

2. TrinX Bicycles:

TrinX is a mainstream bicycle brand in the top 3 leading brands of China along with Phonix (phoenix) or Forever (Eternal). I personally appreciate TrinX more than the other two because of its superior quality and style. The strength of TrinX bikes is the very good price compared to the quality of the bike. Cheap but still spare parts of famous brands such as Shimano, Sram, Quando, Maxis, Tektro, Novatec, Kenda …

2

The design of TrinX is also constantly changing, every year the company releases new beautiful models and improves quality. Therefore, when imported to Vietnam, many products were quickly received. However, the limitation of TrinX is that the high-end models are still diverse and do not have an official distribution system, but are imported and self-guaranteed by shops. Therefore, when choosing to buy TrinX bicycles you must choose reputable and long-term shops with good service to be warranted and maintained in accordance with standards. Avoid home-shop, the price may be a bit cheaper due to the cost of space and manpower, but there will be no after-sales service.

3. Galaxy bike:

This is TrinX’s late-born brother. A part of TrinX’s design team has separated to work for the Galaxy so that you can see the style and style of the Galaxy bicycle bearing the direction of TrinX. However, Galaxy is also shaping its style by hiring European design engineers such as Russia and Italy to come up with ideas and design high-end models according to international standards.
